Af:table with filter option

Question

Hi,
I have a bounded task flow with page-fragments, first activity is method-call(execute-query) and second is a view activity. On the view activity I dropped a read-only, af:table, enabled filters. Although execute query is successful af:table does not display correct records. When I delete af:table and add it again with no filter everything works as expected (also deleted the search region definition from page def file). af:table with filter option adds a search region to executable section of page-definition file, with Empty Criteria in my case. I want af:table to display results after execute-query method activity and decorate the af:table with filters. Filter would be enabled only when users enter filter criteria. Is that possible? Am I missing something?
Best Regards,
Salim

Answer 1

Hi,
I found new problems with my case. When we use filter option with af:table filter criteria is not cleared. Forum search returned Re: Problem with 11g table - filter . Suppose that user enters a criteria and presses enter, this executes query and results are displayed as expected. Then user clears the previously entered criteria presses enter o display all records, and no results are displayed. Looking at the trace for a testcase based on HR schema, I observed that all the bind variables in the query is saved and passivated, Please observe that for every new criteria entry (for the same field, Emp.ENAME) a SQL clause is added at the end. Although one might expect that all the criteria related to af:table filter is cleared and rebuilded for every request rather than saving them all, which results in bad end user experience. So is there a way to go with af:table with filter? Am I missing something?
