cl_salv_table - refresh does not work

jrgkraus — Tue, 24 Mar 2009 09:48:59 GMT

Hello community,

i put a table on a custom control of a dynpro using the class above. Now, after altering the table contents and doing a refresh, the visible table will not show any change.

here is the relevant code:


* The alv object is created like this
  try.
  cl_salv_table=>factory(
    exporting
      r_container = go_joblist_container
    importing
      r_salv_table = go_joblist_alv
    CHANGING
* The table gt_joblist is global...
      t_table = gt_joblist
       ).
  catch cx_salv_msg.
    exit.
  ENDTRY.
  lo_columns ?= go_joblist_alv->get_columns( ).
  lo_columns->set_optimize( abap_true ).

  go_joblist_alv->display( ).

* after a user command, the following code is processed

  data ls_stat type zdb_fspo_stat01.
  ls_stat = go_stat->get_stat( ).
  go_jobs->shift( ls_stat-strtdate ).
  clear gt_joblist. " For test reasons, the table is cleared
*  gt_joblist = go_jobs->get_joblist( ).
  go_joblist_alv->refresh( ).
  cl_gui_cfw=>flush( ).  " I event tried to do a flush - without effect

Can anybody help me?

Thanks to all

Jörg

Have you implemented the Events for the SALV object?

Check demo program: SALV_DEMO_TABLE_REFRESH which works well for the refresh on the button Change Data Records & Select Rows.

What is the scope of the table variable?

I had a similar problem that I fixed by making the table an attribute of the local class, rather than a global variable of the report program. Once I did that, the method that caught the user action saw the updated (sorted) version of the table, not the original.

No, the user action is being initiated by the dynpro that carries the alv (PAI-Processing). I don't see how the implementation of events could help here?

There is no report. It's a object-orientated transaction with a function module that contains a dynpro with the alv on it. The table is a global, private attribute of the main class. I did several similar programs where the refresh works fine...

Your code for refreshing must be triggered form the event handlers of your ALV.

Try to implement Events & the event handlers for your ALV e.g. BEFORE_SALV_FUNCTION.

Sorry, I was misunderstanding your question.

AFAIK, the refresh should work.

Have you tried the set_data method instead? Be aware, it'll wipe your display settings...
