Add new diagram - Encountered an improper argument

[neuron]

Hello,
I'am trying to add new diagram,
but after this code I have error "Encountered an improper argument"
and after I reopen .ea file, the diagram is added to package.
Can somebody help me ?

C# CODE:

public bool EA_OnPostNewMethod(
      EA.Repository repository,
      EA.EventProperties eventProperties)
    {
      EA.Package package = (EA.Package)repository.GetPackageByID(5);
      EA.Diagram diagram = (EA.Diagram)package.Diagrams.AddNew("ExampleDiagram", "Class");
      diagram.Notes = "Example note";
      diagram.Update();

      return true;
    }

Are you sure the type of the diagram you are adding is correct?

Hello,

I changed diagram type to "Activity", which is the first one from help - Built-In Diagram Types.

C# CODE:

...
EA.Diagram diagram = (EA.Diagram)package.Diagrams.AddNew("ExampleDiagram", "Activity");
...

...activity diagram is added immediately, but I still have that error message "Encountered an improper argument"...
