Elements added to an Activity Diagram don't appear

[Jeronimo]

Hello,
I try to write a Jscript which adds an activity diagram to every class and adds for each method of the class an activity to this diagram. Unfortunately the added activities don't appear at the diagram...

[size=10]for(var n = 0; n < methods.Count; n++)
{
    // Get the current method
    var currentMethod as EA.Method;
    var newActivity as EA.Element;
    currentMethod = methods.GetAt(n);
    
    // Create an activity for this method
    newActivity = currentElement.Elements.AddNew(currentMethod.Name, "Activity");
                        
    // Add the activity to the diagram
    var diagramObjects as EA.Collection;
    diagramObjects = activityDiagram.DiagramObjects;
    var activityDiagramObject as EA.DiagramObject;
    activityDiagramObject = diagramObjects.AddNew("l=200;r=400;t=200;b=600;", "");
    activityDiagramObject.ElementID( newActivity.ElementID );
    activityDiagramObject.Update();
    diagramObjects.Refresh();
    Session.Output( "Added activity '" + newActivity.Name + "' to
                             diagram '" + activityDiagram.Name + "'");
    currentElement.Update();
}[/size]

What I'm doing wrong?

Jeronimo,

I think you'll need to user Repository.ReloadDiagram (long DiagramID)
to refresh the contents of the diagram.

PS. I don't think diagramObjects.Refresh() is usefull in your context.

Hello Geert,
thank you for your quick reply! Unfortunately reloading the
Diagram by Repository.ReloadDiagram(activityDiagram.DiagramID)
doesn't help... the diagram is still empty...

P.S.:
I wish you all a merry Christmas and a happy new year!

Looks like you aren't saving the Activity before trying to add it to the diagram.  So the ElementID will still be zero.

Add newActivity.Update();

I'm also no sure why you are doing currentElement.Update();, as it hasn't been modified anywhere in the loop.

Hello Simon M,

unfortunately saving the activity doesn't help... The activities are just still appearing in the project browser but not in the diagram.

Jeronimo,

Could you post an update of your code?
We might be able to spot the error.

Dear all,
i found out whats going wrong... My fault was before the code fragment:
I created a new Diagram, but I didn't save the diagram using the activityDiagram.Update();  -method.
After creating the Diagram I have to save the Diagram before adding elements to it!

Thank you all for your help!
