Title: Adding ActivityParameters to ActivityDiagram via EA API
Post by: vrieg on May 25, 2024, 10:32:14 pm

Hello all,

I want to use EA APi to add ActivityParameters to an ActivityDiagram.
I have added the Activities and identified the GUID of the ActivityParameters correctly.
However, when I am trying to update the diagramobject I am running into a stack overflow during execution.

Does anyone know what could be the issue?
It seems to be this line parameterDiagramObject.Update();
And it is independently caused for iterating through EA.Elements or EA.Diagobjects to add the diagramobject to the diagram.

Adding the ActivityParameters manually via, Features/InteractionPoints/Show works perfectly. However I would like to automate this step if possible.

Code: [Select]


 public static void ShowActivityParametersInDiagram(string activityDiagramGUID, string activityGUID,EA.Repository Repository, OutputMyTab outputTab)
        {
            // Retrieve the EA.Element for the activity using its GUID
            EA.Element activityElement = Repository.GetElementByGuid(activityGUID);
            EA.Diagram activityDiagram = Repository.GetDiagramByGuid(activityDiagramGUID);

            if (activityDiagram != null && activityElement !=null)
            {
              foreach (EA.Element parameter in activityElement.Elements)
                {
                    EA.DiagramObject parameterDiagramObject = activityDiagram.DiagramObjects.AddNew("", "");
                    parameterDiagramObject.ElementID = parameter.ElementID;
                    parameterDiagramObject.Update();                 
                   }
            }
            activityDiagram.Update();
            }
            else
            {
               
                outputTab.WriteDebugMsg($"Error: Unable to retrieve activityDiagram for GUID: {activityDiagramGUID}");
            }
        }

Hard to tell without the stack trace. However, the  activityDiagram.Update is superfluous since you do not change the diagram properties.

Try asking copilot to create the script for you may give you some hints.

I have a shapescript on the ActivityParameters to visualize the direction for in and out.
If I look into the xml of the manually generated ActrivitiyParameters obtained bey Features/InteractionPoints/ShowAll, I am getting this for the diagram objects however, printing digaramobject.sequence or diagramobject.style return 0 for each entry.
Is there a way how to set those parameters before.diagramobject.update()?
I am just wondering if this could cause the stackoverflow.
