Hello,
I have a problem with implementing my editor. I have a diagram element which
behaves in a strange way. When you first drag it into the canvas, it doesn't
appear at all, as if it didn't get created. But when you reopen de diagram,
it is there however (it is also created in the xml file). So apparently it
did get created, but just didn't get displayed. It is however placed at the
top of the diagram in the left .. so the positioning of the element also
went wrong.
My guess is that this is caused by the fact that this figure inherits from
another element which also inherits form another element (situation : nodeA
extends nodeB,nodeB extends nodeC).
=======
| NodeC |
=======
^
|
=======
| NodeB |
=======
^
|
=======
| NodeA |
=======
The element which is at the bottom of the inheritance chain (nodeA) isn't
properly displayed. The intermediate nodes (nodeB) are displayed correctly
and function perfectly. Is there an extra setting in order for this to get
functioning? Or is it simply not supported yet maybe? I was wondering if
anyone of you has ever tried doing something like this?
And secondly, where can I try start searching for the cause of this error,
when an element is not displayed directly. I really need to get this to
work, so any advice is welcome
Thanks in advance,
Kind regards,
Martin Looise

What i've discovered until now, is that the entire
CreateGraphicEditPartOperation(View view)
Isn't called when a new object of this type is created. When you close the
diagram, and reload it, then it IS called however. Anyone has any experience
with problems related to this?
