Hi,  I have a page that displays two datagrid. On clicking the above datagrid, I am trying to call the second data grid placed down using reference set selector. I want more than 1000 records to be displayed by the second grid. But currently it shows error given below: Is there a way to resolve this error? Error in execution of monitored action 'RegularClientAction' (execution id: 1599224610964-21, execution type: CLIENT)   --------   java.lang.AssertionError: assertion failed: Maximum supported depth

Can you add a snapshot of your page in Studio Pro? I think (hope) you have an incorrect way of linking your datagrids.

And have you also tried this with an alternative for the second datagrid: a template grid or a with list view? That might already get you what you need.
