Unable to assign a value in LightSwitch 2012 project - lightswitch-2012

I'm trying to implement the following code into a LightSwitch 2012 project. I'm getting an error when I try to assign the this.ExpenseReport to a value. The error reads "Property or indexer 'LightSwitchApplication.ExpenseReportDetails.ExpenseReport' cannot be assigned to -- it is read only".
partial void ExpenseReportDetails_InitializeDataWorkspace(List<IDataService> saveChangesTo)
{
// Write your code here.
if (this.ExpenseReportId == -1) // -1 means new Report
{ // Create a new ExpenseReport
this.ExpenseReport = new ExpenseReport();
}
else
{
// Get existing Expense Report
this.ExpenseReport = this.DataWorkspace.ApplicationData.ExpenseReports_SingleOrDefault(this.ExpenseReportId);
// Set the name of the Tab to the default field on the Entity
this.SetDisplayNameFromEntity(this.ExpenseReport);
}

The implementation of ExpenseReport does not have a set property, only a get propery. THis means that you can not run the following line:
this.ExpenseReport = this.DataWorkspace.ApplicationData.ExpenseReports_SingleOrDefault(this.ExpenseReportId);
Can you change ExpenseReport to be writable?

local rest api controller does not receive data from repository function-call

Our VS-2022 development project is Blazor WASM Core-6 with local REST-API for data. Using Postman, my testing is not getting data from the controller call to a repository function -- using breakpoints and local debugging -- as one would expect.
The repository function return statement is return Ok(vehicleTrips);. The IEnumerable vehicleTrips data variable contains the correct four records as expected from the DB fetch.
From the controller the call to the repository function is:
var result = (await motripRepository.GetMOTripsByDateRange((int)eModelType.Vehicle, pVehicleList, pDateFrom, pDateTo)!)!;
The controller function signature is:
[HttpGet("byDateRange/{pVehicleList}/{pDateFrom}/{pDateTo}")]
[ActionName(nameof(GetVehicleMOTripsByDateRange))]
public async Task<ActionResult<IEnumerable<MOTRIP>>> GetVehicleMOTripsByDateRange([FromRoute] string pVehicleList, [FromRoute] string pDateFrom, [FromRoute] string pDateTo) {
This is my problem. The result return value from the repository has a return.Value of null -- NOT four trip records as we should.
Additionally, the VS-Studio's 'local'-debugger shows that there are other properties of return such as .Return and .Return.Value.Count as 4 (four).
My question is "what could be causing this"? All of my other rest-api calls and controller calls with Postman work correctly as one would expect.
Did I select the wrong type of "controller" from Visual-Studio? I am not experienced at all in coding classic MVC web-applications. VS-Blazor offer a number of controller-types. In the past, I "copied" a working controller and "changed the code" for a different "model".
Your assistance is welcome and appreciated. Thanks...John
I found out what actually happened to cause the result.Value is null and had nothing to do with the controller-type -- it was in the interpretation of the return value from the repository function.
I found an SO link Get a Value from ActionResult<object> in a ASP.Net Core API Method that explains how to respond to a ActionResult<objecttype> return value in the reply/answer section with the word "actual" is first defined. You will see this word "actual" in my revised code below.
My revised code is posted here with comments both inside the code section and below the code section. My comment inside the code begins with "<==" with text following until "==>"
// Initialize.
MOTRIP emptyMoTrip = new MOTRIP();
MOTRIP? resultMoTrip = new MOTRIP();
IEnumerable<MOTRIP> allTrips = Enumerable.Empty<MOTRIP>();
int daysPrevious = (int)(pTripType == eTripType.Any ? eDateRangeOffset.Week : eDateRangeOffset.Month);
// convert DateRangeOffset to 'dateonly' values.
DateOnly dtTo = DateOnly.FromDateTime( DateTime.Today);
DateOnly dtFrom = dtTo.AddDays(daysPrevious);
// Fetch the vehicle trips by date-range.
var result = await GetVehicleMOTripsByDateRange(UID_Vehicle.ToString(), dtFrom.ToString(), dtTo.ToString());
if ((result.Result as OkObjectResult) is null) { **<== this is the fix from the SO link.==>**
return StatusCode(204, emptyMoTrip);
}
var statusCode = (result.Result as OkObjectResult)!.StatusCode;
if (statusCode==204) {
return StatusCode(204, emptyMoTrip);
}
**<== this next section allows code to get the result's DATA for further processing.==>**
var actual = (result.Result as OkObjectResult)!.Value as IEnumerable<MOTRIP>;
allTrips = (IEnumerable<MOTRIP>)actual!;
if ((allTrips is not null) && (!allTrips.Any())) {
return StatusCode(204, emptyMoTrip);
}
<== this next section continues with business-logic related to the result-DATA.==>
if (allTrips is not null && allTrips.Any()) {
switch (blah-blah-blah) {
**<== the remainder of business logic is not shown as irrelevant to the "fix".==>**

You might be looking in the wrong place. Check if there's an unit test written for this thing (there should be one, especially if it's deployed to production), it should help you understand how it's supposed to be used.
You're inserting records of QMBDataLogging__c but then it seems they're immediately deleted in DeleteDoAsLoggingRecords.deleteTheProcessRecords(processdIds). Whether whatever this thing was supposed to do succeeds or not.
This seems to be some poor man's CSV parser or generic "upload anything"... that takes data stored in QMBDataLogging__c and creates QMB_Initial_Letter__c out of it.
QMBLetteTypeToVfPage__c.getAll() suggests you could go to Setup -> Custom Settings, try to find this thing and examine. Maybe it has some values in production but in your sandbox it's empty and that's why essentially nothing works? Or maybe some values that are there are outdated?
There's some comparison if what you upload into Field1__c can be matched to what's in that custom setting. I guess you load some kind of subtype of your QMB_Initial_Letter__c in there. Record Type name and list of fields to read from your log record is also fetched from custom setting based on that match.
Then this thing takes what you pasted, looks at the list of fields in from the custom setting and parses it.
Let's say the custom setting contains something like
Name = XYZ, FieldAPINames__c = 'Name,SomePicklist__c,SomeDate__c,IsActive__c'
This thing will look at first record you inserted, let's say you have the CSV like that
Field1__c,Field2__c,Field3__c,Field4__c
XYZ,Closed,2022-09-15,true
This thing will try to parse and map it so eventually you create record that a "normal" apex code would express as
new QMB_Initial_Letter__c(
Name = 'XYZ',
SomePicklist__c = 'Closed',
SomeDate__c = Date.parse('2022-09-15'),
IsActive__c = true
);
It's pretty fragile, as you probably already know. And because parsing CSV is an art - I expect it to absolutely crash and burn when text with commas in it shows up (some text,"text, with commas in it, should be quoted",more text).
In theory admin can change mapping in setup - but then they'd need to add new field anyway to the loaded file. Overcomplicated. I guess somebody did it to solve issue with Record Type Ids - but there are better ways to achieve that and still have normal CSV file with normal columns and strong type matching, not just chucking everything in as strings.
In theory this lets you have "jagged" csv files (row 1 having 5 fields, row 2 having different record type and 17 fields? no problem)
Your call whether it's salvageable or you'd rather ditch it and try normal loading of QMB_Initial_Letter__c records. (get back to your business people and ask for requirements?) If you do have variable number of columns at source - you'd need to standardise it or group the data so only 1 "type" of records (well, whatever's in that "Field1__c") goes into each file.

Dynamic list box parameter on jndi datasource in BIRT Report

I made dynamic list box as parameter. if I set data source directly in birt report then list box parameter is coming but if I set the ODA data source on beforOpen event this list box parameter is not working. Please help me.
.
**- Follwing code on beforeOpen event of datasource
var dsName =** reportContext.getHttpServletRequest().getSession().getAttribute("DataSource");
vector = util.getConnection(dsName);
var flag = vector.get(0);
if (flag == '0')
{
this.setExtensionProperty("odaDriverClass",vector.get(1));
this.setExtensionProperty("odaURL",vector.get(2));
this.setExtensionProperty("odaUser",vector.get(3));
this.setExtensionProperty("odaPassword",vector.get(4));
}
else
{
this.setExtensionProperty("odaJndiName","java:/"+dsName);
}
Note- this ODA data source working in report level but it is not working in parameter level

Trigger works but test doesn't cover 75% of the code

I have a trigger which works in the sandbox. The workflow checks the field in the campaign level and compares it with the custom setting. If it matches, then it returns the target to the DS Multiplier field. The trigger looks as follows
trigger PopulateTarget on Campaign (before insert, before update)
{
for(Campaign campaign : Trigger.new)
{
if (String.isNotBlank(campaign.Apex_Calculator__c) == true)
{
DSTargets__c targetInstance = DSTargets__c.getInstance(campaign.Apex_Calculator__c);
{
String target = targetInstance .Target__c;
campaign.DS_Target_Multiplier__c = Target;
}
}
}
}
However, I had problems to write a proper test to this and asked for the help on the internet. I received the test
#isTest
private class testPopulateTarget{
static testMethod void testMethod1(){
// Load the Custom Settings
DSTargets__c testSetting = new DSTargets__c(Name='Africa - 10 Weeks; CW 10',Target__c='0.1538', SetupOwnerId = apexCalculatorUserId);
insert testSetting;
// Create Campaign. Since it would execute trigger, put it in start and stoptests
Test.startTest();
Campaign testCamp = new Campaign();
// populate all reqd. fields.
testCamp.Name = 'test DS campaign';
testCamp.RecordTypeId = '012200000001b3v';
testCamp.Started_Campaign_weeks_before_Event__c = '12 Weeks';
testCamp.ParentId= '701g0000000EZRk';
insert testCamp;
Test.stopTest();
testCamp = [Select ID,Apex_Calculator__c,DS_Target_Multiplier__c from Campaign where Id = :testCamp.Id];
system.assertEquals(testCamp.DS_Target_Multiplier__c,testSetting.Target__c);// assert that target is populated right
}
}
Such test returns the error "Compile Error: Variable does not exist: apexCalculatorUserId at line 6 column 122". If I remove that ApexCalculator part System.assertEquals then the test passes. However it covers 4/6 part of the code (which is 66%)
Could anyone help me how should I amend the code to make the coverage of 75%?
Yes, apexCalculatorUserId has not been defined. The code you were given appears to be incomplete. You'll need to look at the constructor DSTargets__c and see what kind of ID it is expecting there.
At a guess, you could try UserInfo.getUserId() to get the ID of the current user, but that may not be the ID that's expected in the constructor. It would be worth trying it to see if the test coverage improves.
1) Replace apexCalculatorUserId with UserInfo.getUserId()
2) I'm not sure what kind of field is Apex_Calculator__c on campaign. If its not a formula you want to insert a new line before "insert testCamp". Something like:
testCamp.Apex_Calculator__c = UserInfo.getUserId();

Crm 2011 - How to set a default form depending on attribute value (without using Javascript)?

I have a little requirement that is making me crazy:
We have 8 different forms for the Contact Entity.
We also have a pick list with 8 options.
The idea is that based on the option selected we could open that Contact record showing by default a particular form WITHOUT USING JAVASCRIPT in order to avoid performance problems (each record has to be loaded twice). Example:
Forms:
Form 1
Form 2
Form 3
Pick List Values - Default Form:
Form 1
Form 2
Form 3
If Form 3(pick list value) is selected then, the next time I open that record, Form 3 should be displayed by default.
If Form 1(pick list value) is selected then, the next time I open that record, Form 1 should be displayed by default.
I've trayed registering a plugin at the systemform entity, in RetrieveFilteredForms message, updating the userentityuisettings table and I've been able to set a "DEFAULT" that is displayed every time the records is opened regardless the last opened form.
I've trayed registering a plugin at the contact entity, in Retrieve message, updating the userentityuisettings table but I found that Crm only consults the table Once if there is no attribute updated, the following times Crm take the the default form to open value from the cache.
This is an old question but since it's coming up in my searches for this problem I wanted to add my solution.
We use Dynamics CRM 2013. To my knowledge, later versions of 2011 also support this technique.
The form that is displayed when an entity is opened is determined by a few things - the default form, the security roles and fallback settings for a form and the last form used by the current user for that entity. We had a similar problem to the asker where we wanted a different account form displayed based on the value of a form. We were also tired of the constant reload/refresh that javascript techniques are subject to.
I found some blog posts (in particular this one: http://gonzaloruizcrm.blogspot.com/2014/11/avoiding-form-reload-when-switching-crm.html) which mentioned that it is possible to write a plugin to the Retrieve of the entity that allows you to read out the value (LastViewedFormXml) from UserEntityUISettings that stores which form was last used. If it's not the form you want, you can write in the desired value. This avoids the javascript form refreshing.
I had to modify some code from the samples I found to get it to work, but I'm happy with the results. You need to generate an entity class using CrmSvcUtil and include it in the project. You can get your form guids from the url of the form editor.

}
And to address the asker's issue with it only consulting the UserEntityUISettings once, I'm not sure why that's happening. But why not use javascript to change the form when the triggering attribute is changed? That what I do and I haven't ran into any problems with the plugin not displaying the desired for.
EDIT: the OP specified after that he needs a solution without javascript, I leave this reply for future references.
You can use javascript, inside the OnLoad event you check the picklist value and navigate to the desired form. Check this code as example
var value = Xrm.Page.getAttribute("new_optionset").getValue();
switch(value) {
case 100000000:
Xrm.Page.ui.formSelector.items.get(0).navigate();
break;
case 100000001:
Xrm.Page.ui.formSelector.items.get(1).navigate();
break;
case 100000002:
Xrm.Page.ui.formSelector.items.get(2).navigate();
break;
/// ... other cases here
default:
// default form to open when there is no value
Xrm.Page.ui.formSelector.items.get(0).navigate();
}
This is an oldy but a goody... I use CRM Rules to generate Hide Tab and Show Tab actions that essentially show each user role a different form.
Steps:
Create one, massive form with all of the fields you want to display (if you already have many forms, this would include all fields across all forms).
Organize the form into TABS, with each tab showing 'one form' worth of data. (You can also have many TABS for each user group). Typically, I create one 'General' tab that has the key option set that will set the rest of the form up, and any fields that are common across roles / user groups / forms, like status, name, etc...
3) Hide all of the tabs except the General tab by unchecking the visible box on those tab form property forms in the Admin UI.
4) Using CRM Rules (crm-rules.com), you can then bring in the metadata, with the form, and all of the tabs and sections in there. Then you just have to write one rule for each 'form' you are trying to show... Each rule is of this format:
IF User_Role contains 'Sales' THEN Show Tab: Sales
IF User_Role contains 'Marketing' THEN Show Tab: Marketing
You can also do this, of course, with an option set, or any field on the form as the condition... One of the benefits of this approach is that if users cross role boundaries (or some users were part of security roles that could access multiple forms), this technique shows them both forms at once...
HTH somebody, CRM Rules (www.crm-rules.com) generates the JavaScript to make this happen...
