Not able to create CompositeDiagram via Automation

[Sascha Zinflou]

I need to set a CompositeDiagram to an Element via Automation and I am using EA 7.5.850, and I it does not work ;-)

What I am able to reach is:
 - create the diagram as a subnode in the project explorer
 - leaving the element in a state, in which selecting it in any diagram where it appears, and by choosing Context Menu -> Advanced -> MakeComposite results in the desired behaviour: I can navigate from one diagram via the composite object to the more detailed diagram.

What I am not able to reach uo to now is:
 - Creating the composite element with the correct behaviour from the automation interface. The element created has neither the little "infinity-like" symbol showing it is composite, nor can I navigate to the associated model by clicking it.

What I tried up to now is:

Code: [Select]

               

//Creating the element in some package
EA.Element eaElement = (EA.Element)eaParentPackage.Elements.AddNew("someName","Activity");
eaElement.Stereotype = "BusinessProcess";
eaElement.Update();
eaParent.Elements.Refresh();

//trying making it composite
tryToMakeCompositeBefore();

//Creating the Subdiagram
EA.Diagram eaDiagram = (EA.Diagram)eaElement.Diagrams.AddNew("someName", "Analysis");
eaDiagram.Update();
eaElement.Diagrams.Refresh();
eaElement.Update();

//trying making it composite
tryToMakeCompositeAfter();


What I tried as well in tryToMakeCompositeBefore as in tryToMakeCompositeAfter, was

Code: [Select]

eaElement.Subtype = 8;
eaElement.TaggedValues.AddNew("diagram", "EAID_" + eaDiagram.DiagramGUID.Substring(1,eaDiagram.DiagramGUID.Length-2)); eaElement.TaggedValues.Refresh();

I tried also to use only one of the rows. The idea to add the tagged value came from analyzing the difference between XML-Exports between a working and a non working version.

Any help would be appreciated, as well as uncommented sample code creating working composite elements in any other context.

Hi Sascha,

The "secret sauce" you are looking for is documented in: Setting element as Composite Element/NType=8 which can be found using the [Search] button between [Help] and [My Center] above.

You should read the whole topic for a more complete picture...

HTH,
Paolo

Hi Paolo,

thank you very much, as well for the link as for the hint using the Search-Button. I used the small search bar on the right before posting and it is just now that I learned: that one does not really search the entire forum :-(

I will give a short feedback again, when I have read the thread and tried the solution proposed.

Hi Paolo,

I am coming back to the problem just today, and with the thread you mentioned it works.

Finally a                                
_repository.Execute("UPDATE t_object SET PDATA1 = '" + eaDiagram.DiagramID + "' where Object_ID = " + eaElement.ElementID); helped.

I will just have to think on how I will get this one through a code review ;-)

So thanks again for your help.

Take care
Sascha

Hi Sasha,

I am currently working on the same "wish". I am trying to set up composits by an addin.

Unfortunately the repository.execute (see C# snippet below) does not bring the required result  

string sqlStr = "UPDATE t_object SET PDATA1 = '" + dgId + "' where Object_ID = " + element.ElementID.ToString();
                repository.Execute(sqlStr);

just won't work..
Is there something I am missing?

Rainer,

Have you checked the dbError.txt?
If there is something wrong with the query then it might have reported it there.
Otherwise I guess it just didn't find the record you are trying to update.

Hi Geert,

I don't get a db error. The sql seems to be excecuted ok.
I tried different sql text for example putting the element Id in quotes. There I got a db error.

Rainer,

If I remember correctly the database update was only part of the solution.
Have you also done the the rest?

Hi Geert,

this morning I received  a response from sparx concerning the issue including a vb sample hot to handle the subject. It seems to work ok ..so far..

By the way.. yes there was more to the solution which I was missing to do ;-)

Thanks for responding
Rainer

Hello,
Could you please post an example how it is working ?
