Adding New Row to Assignment Block

Hi,

I created a custom table assignment block to the Membership overview page. The context node is a custom model context node.

There is an "Add" button present to add new entries to the AB. In the Add button I have added the code:

lr_entity - root object entity.

      lr_tx ?= lr_entity->get_transaction( ). 

me->view_group_context->set_view_editable( me ).

      me->view_group_context->set_associated_tx_context( lr_tx ).

      lr_partmsh_entity = lr_entity->create_related_entity( 'XXXXX' ).

      IF  lr_partmsh_entity IS BOUND.


        lr_partmsh_entity->deactivate_sending( ).

        typed_context->yparticmsh->collection_wrapper->add( lr_partmsh_entity ).

      ENDIF.

When I click on the Add button, a new line is getting added. But it is not editable. And the GET_I methods of the attributes of the table AB is not getting called.

Please provide some valuable suggestions.

Regards,

Heera
