Hi,

I discovered that the behavior when drawing a new node has changed in v4. I used the CustomBehavior trick to

1. draw a node inside another node (container),
2. cancel it on Diagram_NodeCreating when releasing the mouse button and
3. show a node creation dialog (editor) on NodeCreateCancelled.

Previously, with v3.9, the modal dialog appeared and the node remained in the background (see the screenshot attached). Now, any click inside the container opens the dialog. Although I haven't started drawing it yet. And even if I draw a node, it will disappear when the dialog opens.

Could you please tell me how to return the previous behavior, where the dialog appears only when the node has actually been drawn and remains visible on the diagram until the dialog is closed?

Let me attach a test project where this case is reproduced.

Thanks,
Kostya

Hi Slavcho,

Thank you for the quick response and fix! Now it works correctly, as before.
