Datagrid substack question

[Knapp Martin]

I'm developing an app that has a half dozen template stacks that users can edit. These each have a datagrid. I made a "master" template stack with the common features and then cloned this stack and modified the clones for that stack's specific features. But as the datagrid created a substack and each has the same name in the individual stacks, I get the dreaded "a stack by this name is already open" when I close one stack and open the next. I set the "purge stack on close" to true but I still get the message occasionally (which makes no sense). So I thought I would change the name of the datagrid sub stack to a unique name in each stack but that breaks the connection to the actual datagrid and causes errors. Any advice on what I should do?
