How to create Composite through Automation

[oliver2007]

Hello,

Through the automation interface I create a diagram under an element. After creating the diagram I want to make the element a Composite.
I am able to to set the subtype of an existing element to 8 which should turn the element into a Composite. When I right click on the changed Element the Composite box is ticked.
But the Element does not work like a Composite the double click does not lead to the underlying diagram and the rendering of the element does not change.

Any suggestions?

Thanks

I think you have to set the diagram's ParentID to make the element behave like it should.

The Parent_ID is set to the element.
If I make the element Composite by hand, the element looks exactly the same in the database as the one created by automation.

I'm at my wit's end then. You'll have to wait for one of the big shots to find a solution. Or send a support request to Sparx, they usually give you an answer on the next (Australian) day.

There's a field in t_object called NType. [I think that's it, it's been a while.] For a Class, you need to set this to 8, rather than the default of 0. I am not sure whether these values are the same for all classifiers, but I suspect they are.

I do not know - actually I do not remember - if this can be set by any API call. It is worth trying the Subtype property, which maps to 0 for 'normal' classifiers.
