Hi Folks,
I found the solution to my problem: Method BUILD_TABLE of the table context node is used to build the internal list (attribute SELECTION_TAB) of selected table lines that is used by the
<chtmlb:configTable> tag.
This method is called before method DO_PREPARE_OUTPUT is executed. So when I mark the entities in the do_prepare_output-method, the table is already built and the selection_tab attribute of the context node is populated without selected lines.
Solution is to call method BUILD_TABLE again after my coding in method DO_PREPARE_OUTPUT is executed.
Cheers,
Jens
