Reported for: Toolset Views 1.12
Resolved in: Toolset Views 2.0
Toolset Views lets you create Views inside other Views, and set filters based on that nested structure. For example, you can create a View that lists users, and then add another View inside it for each returned user, listing posts created by him.
When the inner View has AJAX pagination enabled, the relation with the outer View was lost and the returned results for the second and other pages were wrong, if not empty. Also, in this scenario the query filters that should get their data from the global current page were failing to do so in some cases.
There is no solution as of now, but a fix will be included in an upcoming release for Toolset Views.
