Hello,

This issue has been inactive for days. Has there been an update on this ?

I am also having problems with group by in lazily loaded tables. When I try to do a groupby, I get a heap exception that my memory is full. I am not sure if this is icefaces issue or my code issue, but I would be more certain if this issue has been fixed.

Thank You.

Committed new feature to 4.0 trunk at revision 43814 and to 3.3 EE maintenance branch at revision 43815. Added 'sortWhenGrouping' attribute to ace:column to disable automatic sorting when using groupBy.

Tested with ICEfaces 4 trunk and ee-3.3.0 maintenance branch r43821.
The test application is set up with 2 columns that each have sortWhenGrouping=true. When first arriving at the page the columns can be sorted. After setting the controls to be hidden, then back to shown, the columns can no longer be sorted unless the Name column is sorted or the page is refreshed.

Added logic to re-apply all the event listeners to the sort controls whenever they're updated in the client (at revisions 43826 and 43827).

Tested with ICEfaces 4 trunk r43829. Tomcat 7, IE 11, FF 33, Chrome 39. Issue still remains, after setting the controls to be hidden, then back to shown, the columns can no longer be sorted unless the Name column is sorted or the page is refreshed.

Committed fix for issue with not being able to sort column after turning 'sortWhenGrouping' off and back on at revisions 43851 and 43852.

Verified ICEfaces4 trunk r43852, Tomcat 7, IE 11, FF 33, Chrome 39.
Unable to verify using ee-3.3.0 maintenance branch at this time as there other issues with dataTable that may be interfering.

Changed use of ice.ace.instance for widgetVar in 3.3 EE maintenance branch at revision 43853.

Verified ICEfaces ee-3.3.0 maintenance branch r43860. Tomcat 7, IE 11, FF 34, Chrome 39.
