ACAPI_CallUndoableCommand Access violation reading location 0x0000000000000048

Anonymous
Not applicable
Hi.
I call ACAPI_Property_CreatePropertyDefinition api, and the return code is NoError.
But I don't why the access violation occurs.

I call ACAPI_Property_CreatePropertyDefinition in the callback of APINotify_Open event.

Archicad version 22.

I'm pretty sure you can't process undoable actions during the callback for a project event notification. The right approach would be to ask ARCHICAD to notify you when it's appropriate to action this process – I suggest that you take a look at ACAPI_Command_CallFromEventLoop
