Hi,

Deleting nodes does not always work.
I use
diagram.setDelKeyAction(DelKeyAction.DeleteSelectedItems);

Do I need anything else?


Regards,
Kuzya

Hi,

Maybe the diagram does not have the keyboard focus, try first clicking on it to make it acquire focus. Also check if you aren't stopping deletion from nodeDeleting event handler.

Hi,

In "KeyboardInputDispatcher." the focus element of the diagram is checked if the object on which the keyboard event is executed. The first time you open the dialog this is also true and the deletion works correctly. As soon as you open a dialog the second time in which the diagram is created, the comparison seems to be no longer true.

What could be the connection?

Kuzya

Hi,

By opening a dialog do you mean a new browser window or some DOM element in same window? If it's in same window, try calling document.body.removeChild(diagram.focusDiv) when closing these dialogs.
