How to modify lines in table view?

Hi,

I have custom table view.

I populate the table with a custom query:

query = cl_crm_bol_dquery_service=>get_instance( 'ZAPPLICANT_QUERY' ).

    query->add_selection_param( iv_attr_name = 'OBJECT_ID'

                                     iv_sign = 'I'

                                   iv_option = 'EQ'

                                      iv_low = lv_object_id

                                     iv_high = '' ).

    lr_coll ?= query->get_query_result(  ).

    IF lr_coll IS BOUND.

      me->typed_context->applicant->collection_wrapper->add_collection( iv_collection = lr_coll  ).
    ENDIF.

When i try to modify some lines of the table and press enter, only the first line is updated correctly.

The fields of the other lines is read-only and not changeable.

How do I make "changeable"all the fieldsof mytable?

Please help me.

Thanks,

Max
