Instead of hardcoding the value of formName in the task extension property of modeler, I need to place the formName value as a variable(e.g., ${formname}).
This is implemented in one of our listeners i.e; FormConnectorListener to get the extension property value in dynamic. Please refer https://github.com/AOT-Technologies/forms-flow-ai/blob/master/forms-flow-bpm/src/main/java/org/camunda/bpm/extension/hooks/listeners/task/FormConnectorListener.java
You can add a java listener that should implement org.camunda.bpm.engine.delegate.JavaDelegate and can access the extension property with the general xml api.
public void execute(DelegateExecution execution) throws Exception {
CamundaProperties camundaProperties = execution.getBpmnModelElementInstance().getExtensionElements().getElementsQuery()
.filterByType(CamundaProperties.class).singleResult();
Collection<CamundaProperty> properties = camundaProperties.getCamundaProperties();
for (CamundaProperty property : properties) {
System.out.println(property.getCamundaValue());
}
}
In the above overriden method you can get the variable by using:
execution.getVariable(StringUtils.substringBetween(property.getCamundaValue(), "${", "}"));

I tried to use the Generate() function only if a variable has changed without having to check it every frame. I used the following tutorial to achieve this. but for some reason, whenever i try to set the variable, I get this error:
ArgumentException: GetComponent requires that the requested component 'List`1' derives from MonoBehaviour or Component or is an interface.
the script:
public GameObject CEMM;
private int ListLength;
public static int ListLengthProperty
{
get
{
return JLSV.instance.ListLength;
}
set
{
JLSV.instance.ListLength = value;
JLSV.instance.Generate();
}
}
private void Awake()
{
instance = this;
}
I tried to set the value like this: JLScrollView.ListLengthProperty = JLScrollView.instance.CEMM.GetComponent<List<JLClass>>().Count;
The generic type parameter that you use when calling GetComponent must be a class that derives from Component (or an interface type). List is a plain old class object, which is why you are getting the exception from this:
GetComponent<List<JLClass>>()
I'm not really sure what value you are trying to assign to the property. If you are trying to get the number of components of a certain type on the GameObject you can use GetComponents.
JLScrollView.ListLengthProperty = JLScrollView.instance.GetComponents<JLClass>().Length;
I need to make some changes on closeOk of SalesEditLines form. As I know, I am not able to change the standard methods, so I need to create an event handler for closeOk.
[PreHandlerFor(formStr(SalesEditLines), formMethodStr(SalesEditLines, closeOk))]
public static void SalesEditLines_Pre_closeOk(XppPrePostArgs args)
{
FormRun sender = args.getThis() as FormRun;
Object callerObject = sender.args().caller();
}
The question is - how can i access a SalesFormLetter through SalesEditLines form formRun using PreHandler?
You can see the following line in init method of SalesEditLines form
salesFormLetter = element.args().caller();
So your callerObject is an instance of SalesFormLetter class, you need just cast it to proper type.

I'm using CSLA latest release and trying to add a row with default items to the collection. What I've noticed is the default constructor of the Foo class is called instead of the AddNewCore in the FooList Class. I am unable to get the AddNewCore or the Child_Create methods to get invoked when a new row is added in a XamDataGrid row. (A row is added, but it is from the default constructor of the FooLine Class--i.e. no default values and no MarkAsChild attribute.) Here is the code snippet that is in the FooList class:
protected override FooItem AddNewCore()
{
var item = DataPortal.CreateChild<FooItem>();
MarkAsChild();
Add(item);
return base.AddNewCore();
}
protected override void Child_Create()
{
var item = DataPortal.CreateChild<FooItem>();
MarkAsChild();
Add(item);
base.Child_Create();
}
What am I doing wrong?
AddNewCore() method exists in client side CSLA class 'ExtendedBindingList' with 'void' return type and same method is exists in server side class 'ObservableBindingList' with return type 'ListClass'. So we required to call run time client side method from server side.
Please refer below code for the same.
#if SILVERLIGHT
protected override void AddNewCore()
{
var item = DataPortal.CreateChild<FooItem>();
Add(item);
}
#endif
For information: The reason the above code does not work has to do with the way WPF invokes the New method. Typically, in other frameworks it is possible to hook on to that event, intercept it, and return with default data. With WPF, it is necessary to check the RecordAdding, or RecordAdded trigger events and process the invocations by hand.
In my case, the WPF would look like:
<i:Interaction.Triggers>'
i:EventTrigger EventName="RecordAdded">
<ei:CallMethodAction TargetObject="{Binding}"
MethodName="CreateDefaultAddressValuesCommand" />
</i:EventTrigger>
In the view model:
var idx = FooInformation.FooAddressList.Count - 1;
var address = await FooAddress.CreateAsync();
FooListing.FooAddressList[idx] = address;
I wanted to know if there exist a way of retrieving the actual method name associated to a rest service provided. Lets suppose my url is http://localhost:8080/v1/mytesturl now i want to retrieve the actual method name that is associated with this url.
Actually we are maintaining some key/value pair specific to the method that we have created and i need to make some checks based on the method name that gets executed using these values.
Plz let me know if there exist some way to do that..
Simply get the method name from the Object class.
#RestController
#RequestMapping("")
public class HomeController {
#RequestMapping("/mytesturl")
#ResponseBody
public String getMethodName() {
return new Object(){}.getClass().getEnclosingMethod().getName();
}
}
i got the solution by using this
Map<RequestMappingInfo, HandlerMethod> handlerMethods = RequestMappingHandlerMapping.getHandlerMethods();
HandlerExecutionChain handler = RequestMappingHandlerMapping.getHandler(requestr);
HandlerMethod handler1 = null;
if(Objects.nonNull(handler)){
handler1 = (HandlerMethod) handler.getHandler();
handler1.getMethod().getName()
}
this provide me with what i wanted..
what happens if you implement an automatic property
public string Foobar { get; set; }
and then code the corresponding variable
private string foobar = string.Empty;
Will the automatic property use this variable or does the compiler generate
an additional variable?
No, the automatic property will not use your variable. It would be just like any other field called foobar.
The name smilarity does not influence the compiler in any way.
The compiler will generate a field behind the scenes but you do not have access to the backing field of the automatic property in any way.
This post shows how things work at the IL (Intermediate Langauge, Assembly of C#) level.
The compiler won't use that variable, no. To use your variable you will have to write
private string foobar = string.Empty;
public string Foobar
{
get { return foobar; }
set { foobar = value; }
}
If you have Resharper, you can set up templates to do this. Resharper will also generate a getter from an unused private variable for you.
Why would it? Backing field doesn't have to be (and often isn't) named this way.
