I've created a workflow utilizing the script task (exam_result as integer, exam_grade as integer, remarks as string) job. In the user task, i created a form reference (with textfield) that will handle the data entry of exam result.
The exam result text field should be passed to the exam_result variable which will be evaluated thru decision table task.
What is the best practice to send data from form field control to script task variable or vice versa?
Your help is highly appreciated, thank you.
Store these values into execution variable and you should be able to access them across all the tasks.
You can use task listeners to read the form values and store them into execution variables like below.
execution.setVariable('exam_result',task.getVariable('exam_result'));
execution.setVariable('exam_grade',task.getVariable('exam_grade'));
execution.setVariable('remarks',task.getVariable('remarks'));
If you want to access them in another task listeners,
var examResult = execution.getVariable('exam_result');
var examgrade = execution.getVariable('exam_grade');
var remarks= execution.getVariable('remarks');
This is on the delegates side, you can access them like below.
int examResult = (int) executionVariables.get("exam_result");
int examGrade = (int) executionVariables.get("exam_grade");
string remarks = (string) executionVariables.get("remarks");
Hope this helps you.
Please let me know if it not clear to you.

I am trying to inject agents from a database into a specific source block. The database consists of 2 columns of "OrderType" & "OrderAmount". I wish to inject "OrderAmount" of agents of their corresponding "OrderType" into this source, while retaining the differentiation (I.E. by storing a parameter attribute ID of each entry/agent in the corresponding agenttype of the source block).
I have saved the entries from the database in collections and constructed a table as such (For both arrays; type = double):
double [][] ArrayCustomerOrders = new double [coll_CustomerOrderType.size()][2];
for (int i = 0; i < coll_CustomerOrderType.size(); i++) {
ArrayCustomerOrders[i][0] = coll_CustomerOrderType.get(i);
ArrayCustomerOrders[i][1] = coll_CustomerOrderAmount.get(i);
}
I tried playing around with the source block calls of inject() function in the same event as I constructed the order table in, but was unable to inject eligible arguments.
Does anyone have a suggestion on how to go about this?
In your case, you can simply replace the Source block with an Enter block (named "myEnterBlock"):
Create an empty agent population pop_Orders with an agent type that has 2 parameters p_Type and p_Amount.
In your for-loop code, when you have the current order type and amount, create such an agent and push it into the Enter block directly:
myEnterBlock.take(add_pop_Orders(currentType, currentAmount))
I would like to make a call into the ServiceNow SOAP webservice to start an instance of a specific web service.
I can find the WSDL for functions like incident.do but seem to be missing the step needed to find the proper table/endpoint for workflows to start.
If you want to start a Workflow via SOAP I think the only way to do this is to create a Scripted Web-Service or a Custom Processor.
In there you will have to define a script which starts your Workflow.
var w = new Workflow();
var context = w.startFlow(id, current, current.operation(), getVars());
In this wiki article you can find API Methods for Workflows.
The tricky bit is getting the variables into the Workflow.
While this sounds easy, in fact it isn't.
If your workflow runs on the table sc_req_item (which is likely if you are dealing with Request Fulfillment), you first need to set the Property (sys_properties) glide.workflow.enable_input_variables to true, because otherwise, you will not be able to add normal Input variables to your workflow.
Then, add the Input variables to the workflow. Note that you have some nifty datatypes available there. Note for example the "Data Structure" type.
All Input variables are treated like custome columns (in fact they are columns of a workflw-specific table). That is why the names start with u_.
Lets say, you define an input variable called u_dynamic_vars (Datatype "Data Structure").
Here is how to call the workflow:
var wf_name = "Name of your workflow";
// Instantiate JSON machinery
var parser = new JSON();
//Declare an instance of workflow.js
var wf = new Workflow ();
//Get the workflow id
var wfId = wf.getWorkflowFromName (wf_name) ;
//Start workflow, passing along object containing name/value pairs mapping to inputs expected by the workflow
var vars = { } ;
// Prepare the JSON Datastructure
var obj ={"name":"George",
"lastname":"Washington"};
// Encode the data
vars.u_dynamic_vars = parser.encode(obj);
vars.u_new_email = "inject#new.com";
// Get a specific RITM
var gr = GlideRecord("sc_req_item");
gr.get("18d8e9740f4013002f504c6be1050e48");
gs.print(gr.number);
// Start the Workflow with a "current" record
wf.startFlow(wfId , gr , "update" , vars ) ;
// You may also pass null, then current is null.
wf.startFlow(wfId , null , "update" , vars ) ;
In the workflow, you then unpack the data like so:
// Let's unpack it. For some reason, intantiating the parse won't work here...
payload = JSON.parse(workflow.variables.u_dynamic_vars);
gs.print("payload.first_name:" + payload.name);
Also note that a workflow does not necessarily need to run on a table.
To achieve this, choose "global" as table name when defining the workflow.
I am trying to create some joblets in Talend that will speed up some processes.
I have an input from a MSSQLInput, the results are then sorted and filtered a little. Then I have a tMemorizeRows and a tJavaFlex, the purpose of this is to memorize the rows in a column to preform a count. The count is based on a customer ID, once the the id changes the count starts back to 1 and the proccess begine again and continues to the end. I have refactored this as a joblet but it does not work, the error is:
ID_tMemorizeRows_1 cannot be resolved to a variable
I have a tJavaFlex which starts with
int counte = 1;
The Main code is
if(ID_tMemorizeRows_1[0].equals(ID_tMemorizeRows_1[1]))
{
counte = counte + 1;
}
else
{
counte = 1;
}
context.Enqnum = counte;
The Enqnum variable and is created correctly and added into a tMaps component.
Does anyone know why this is happening, one person told me it is because when you move something to a joblet it gets a new/different name so it has to be specifically called in the Java, if this is the case how do I find the name out?
Thank you
Rich
I do have a resolution. I have tried to add images however my reputation is not high enough.
When using joblets we know that Talend essentially recycles the code used in the joblet by inserting it into the code for the main job.
This is the joblet I have created, i know it works because I have refactored it to a joblet instead of building it from sctatch. What its doing is simply memorises row 0 and row 1 in an ordered data set, the java performs a count and the tMap appends the result to the job (as Mentioned above).
(I will try it inser image in my question, I do not have enough reputation point to insert it into a question).
When the job is run it runs fine. But problems occur when I want to reuse the same joblet in another part of the job. What Talend does is it assigns names within the source code to each component depending on the name of the joblet.
For example, if the Joblet was called ThisJob, then tMemorizeRows_1 would be called ThisJob_1_tMemorizeRows_1.
The row within the component (in this example ReferenceID) would renamed as:
ReferenceID_ThisJob_1_tMemorizeRows_1.
But when you add a second joblet to your job it gives it a new name, eg ThisJob_2. This name will be different depending on how much you have been altering your job before you add the second joblet. Therefore the number within the name will depend on this activity.
If you add the joblet into your job immediately then the joblet would be called ThisJob_2, if you have added 5 other components before you add it in then the joblet is likely to be called ThisJob_6 etc. (I'm not 100% sure how talend renames components)
When you add a joblet, You can see the name of the joblet on the joblet component, this then reverts back the the original joblet name when you create any links/joins to other components.
Its also important that each component within the code is assigned to a variable called currentComponent.
Resolution
What I did was used the Java code to split the name using the code below. This way I can get the current name of the of the joblet and use this name in my Java.
String string = currentComponent;
String[] parts = string.split("_");
String part1 = parts[0];
String part2 = parts[1];
String joblet = part1+'_'+part2;
String newrow = "ReferenceID_"+joblet+"_tMemorizeRows_1";
I hope this makes sense.
Thanks
I have a form called 'detail' which shows a detailed view of a selected record. The record is selected from a different form called 'search'. Because I want to be able to open multiple instances of 'detail', each showing details of a different record, I used the following code:
Public detailCollection As New Collection
Function openDetail(patID As Integer, pName As String)
'Purpose: Open an independent instance of form
Dim frm As Form
Debug.Print "ID: " & patID
'Open a new instance, show it, and set a caption.
Set frm = New Form_detail
frm.Visible = True
frm.Caption = pName
detailCollection.Add Item:=frm, Key:=CStr(frm.Hwnd)
Set frm = Nothing
End Function
PatID is the Primary Key of the record I wish to show in this new instance of 'detail.' The debug print line prints out the correct PatID, so i have it available. How do I pass it to this new instance of the form?
I tried to set the OpenArgs of the new form, but I get an error stating that OpenArgs is read only. After researching, OpenArgs can only be set by DoCmd (which won't work, because then I don't get independent instances of the form). I can find no documentation on the allowable parameters when creating a Form object. Apparently, Microsoft doesn't consider a Constructor to be a Method, at least according to the docs. How should I handle this? (plz don't tell me to set it to an invisible text box or something) Thanks guys, you guys are the best on the net at answering these questions for me. I love you all!
Source Code for the multi-instance form taken from: http://allenbrowne.com/ser-35.html
Inside your Form_detail, create a custom property.
Private mItemId As Long
Property Let ItemID(value as Long)
mItemId = value
' some code to re query Me
End Property
Property Get ItemId() As Long
ItemId = mItemId
End Property
Then, in the code that creates the form, you can do this.
Set frm = New Form_detail
frm.ItemId = patId
frm.Visible = True
frm.Caption = pName
This will allow you to pass an ID to the new form instance, and ensure it gets requeried before making it visible. No need to load all of the results every time if you're always opening the form by Newing it. You let the property load the data instead of the traditional Form_Load event.
This works because Access Form modules are nothing more than glorified classes. Hope this helps.
You could try applying a filter:
frm.Filter = "[ID] = " & patID
frm.FilterOn = True
The Record Source of the Detail form will need to be set to the table to which the ID belongs.
UPDATE
As you requested, here is the code to set the RecordSource:
frm.RecordSource = "select * from TableName where [ID] = " & patID
This is probably cleaner than using a filter given that a user can remove the filter (depending on the type of form).
After a few hours searching, I couldn't find any solution to this little problem I'm having.
I have a query that retrieves one of its criteria from a form. I have referenced correctly the value on the form from the query, and it works, but what I wanted to do is a bit more complicated: when the form is closed, I want to launch the query with a "default value".
I tried to do it in 2 different ways:
a) Defining an "IIf" at the query criteria: I would need a function that checks if the form from which I retrieve the values is open.
b) Defining public variables with a default value, which would be changed from the form: I don't know where/when to initialize the value of the variable.
Does anyone have a better idea on how to do this?
TL;DR: Query gets criteria from form when it's open. If form is closed, query uses default value. HELP!
You can create a VBA function in a module to do this :
Function MyCriterion() As Long
MyCriterion = 1234 ' default value
If CurrentProject.AllForms("MyForm").IsLoaded Then
MyCriterion = Forms("MyForm").MyControl.Value
End If
End Function
