AET Table refresh and update issue

Team,

I have created AET table as an assignment block, now as per requirement, I have to manage entries in AET table view dynamically.

Example, If stat date gt 5/11/2014, I have to fill AET table with 10 records, otherwise 5 records. I have written code in DO_PREPARE_OUTPUT of AET table view using normal bol programming like clear collection, After that create entity for table view by using factory class and then add to the table collection.

me->typed_context->aet_table->collection_wrapper->clear( ).

But this normal logic is not working properlt in AET table view.

Let me know , how to build new entities to AET table view using bol and also let me know how to clear the AET table view.

Thanks!!
