Funny Problem with method GET_GROUPED_COLUMNS

Question

Hi All,
I am encountering a funny problem. I need to provide all Grouped Columns of my Web Dynpro Table. I used the following coding to do this:
lt_col_grp = lo_table->get_grouped_columns( ).
Now, for one table this methode return all Grouped Columns and for another table it returns not only the Grouped Columns, but also the NON Grouped Columns!!!
In the debugger this looks as follows:
1     *->{O:1752*\CLASS=CL_WD_TABLE_COLUMN}*
2     ->{O:1755*\CLASS=CL_WD_TABLE_COLUMN_GROUP}
3     ->{O:1757*\CLASS=CL_WD_TABLE_COLUMN_GROUP}
4     ->{O:1759*\CLASS=CL_WD_TABLE_COLUMN_GROUP}
5     ->{O:1761*\CLASS=CL_WD_TABLE_COLUMN_GROUP}
6     ->{O:1763*\CLASS=CL_WD_TABLE_COLUMN_GROUP}
7     ->{O:1765*\CLASS=CL_WD_TABLE_COLUMN_GROUP}
Why is that??
Does anybody know how to delete the lines that are not of type CL_WD_TABLE_COLUMN_GROUP?
Thanks,
Johannes

Hi Maik
It seems you have solved your problem. There are some actions clearing all selection and scrolling info. And since you every time create a new instance or call some method which clears your selections your selections table is lost.
For a screen session, you should use "set_table_for_first_display" for just once and for next PBO triggers you should execute the method "refresh_table_display".
