If so then modifying your page to have this should work.
And if that doesn't work, you may want to wrap your apex:outputPanel with an apex:actionRegion to make it more explicit
All Answers
- You load the page
- Click on the Attendence tab
- Click search button
- Nothing appears
- Click on the Student tab
- Choose something
- Click on the Attendence tab
- Results appear?
If this is the case, it's probably because you are not re-rendering the results list section of your Visualforce page. If you do the steps above but skip step 6, do the results appear?If so then modifying your page to have this should work.
