[former_member206441]

Dear Experts,

Im having two columns in my table and im using filter in my table, In onfilter event i written the code

wd_this->table_control->apply_filter( ).

And in the table column i enabled the isFiltered option and i also binded the filtervalue to a variable of type string.

when i execute my program and give input in filter field the following error occurs,

The following error text was processed in the system EBP : Access via 'NULL' object reference not possible.

The error occurred on the application server kaar-server15_EBP_00 and in the work process 1 .

The termination type was: RABAX_STATE

The ABAP call stack was:

Hi,

You must not have defined wd_this->table_control

You need to do this in WDDOMODIFY and get table control in global variable as follows:

  CHECK first_time EQ abap_true.

**Get table handler for table from view
  DATA: l_table TYPE REF TO cl_wd_table.

* Get reference of the table view element
  l_table ?= view->get_element( 'TBL_MAIN' ).

* Get reference to the Filter & Sorting API
  wd_this->table_control ?= l_table->_method_handler.

Hope this helps!

Thanks,

Tejaswini

Hi,

When you debug in filter action. Can you tell me, wd_this->table_control is initial or not?

Error Access via 'NULL' object reference not possible. comes only when it is not defined.

Hi,

It is clear that means, it has not get defined.

To define it you need to use the logic in WDDOMODIFY.

  CHECK first_time EQ abap_true.      "Only for first time, get table's handler in global variable
 
**Get table handler for table from view
  DATA: l_table TYPE REF TO cl_wd_table.
 
* Get reference of the table view element
  l_table ?= view->get_element( 'TBL_MAIN' ).    "Name of Table UI element
 
* Get reference to the Filter & Sorting API
  wd_this->table_control ?= l_table->_method_handler.

This way, you will get Table's Handler and it will not dump.

Thanks,
