I am developing a new python toolbox (ArcMap 10.6.1, windows 10) and I have been experiencing issues with the GPValueTable data type which causes ArcMap to crash. It mainly happens when a user starts changing the values in the table manually (please see the image below). The odd thing is that ArcMap does not crash every time but it seems more random. Would anyone know what the cause might be? Has anyone experienced the same or similar behaviour?
In a dump file that gets generated when ArcMap crashes I get the following information:
Exception information: The thread tried to read from or write to a virtual address for which it does not have the appropriate access. - I would like to point out that I am logged in as an administrator.
Please see the attached source code for the python toolbox "Toolbox_with_valueTable.zip" and the dump file.
