The temporary objects in a datagrid change dynamically IF data is reloaded. What if the developer is using a datagrid as a static list and needs to restore the contents? I think the solution is to bypass the temporary objects of a datagrid, instead saving the datagrid data in some fashion (see my functions for converting an array to text and back again) as a special case. The first time a stack is "versioned" it could present the dev with a list of datagrid objects and allow the dev to choose between versioning the contents or the structure + data. 

Where things are going to get really dicey is stacks that are constantly creating and deleting objects and groups. I am not a big fan of using Livecode this way, but people do, so there you are.
