ListGrid Group Collapse/Expand button does not work on IE8, IE9

[tvizgaitis]

Hi Isomorphic,

I have an issue with ListGrid Group Collapse/Expand button on IE8, IE9
then grid.setCollapseGroupOnRowClick(false).
(FF and Chrome is fine)
See screenshoot "grid.jpg" marked as 1.

SmartGWT version 5.0p (v10.0p_2014-10-21/Pro Deployment) (tested also on 5.1d (v10.1d_2015-07-27))
GWT-2.6.0

ListGrid:

grid.setCanSort(false);
grid.setCanFreezeFields(false);
grid.setCanGroupBy(false);
grid.setCanAutoFitFields(false);
grid.setCanPickFields(false);
grid.setCanReorderFields(false);
grid.setAutoFetchData(true);
grid.setAlternateRecordStyles(false);
grid.setGroupByField("Z_GROUP1","Z_GROUP2","Z_GROUP3"); 
grid.setShowGridSummary(false);  
grid.setShowGroupSummary(true);
grid.setShowGroupSummaryInHeader(true); 
grid.setGroupByFieldSummaries("Z_GROUP3");
grid.setShowGroupTitleColumn(false);
grid.setGroupTitleField("Z_NAME");
		
grid.setCollapseGroupOnRowClick(false);

this option expands initially, but still USER can't Collapse/Expand any Group:

grid.setGroupStartOpen(GroupStartOpen.ALL)

Please clarify what the issue is: collapseGroupOnRowClick:false is documented to avoid collapsing the group if the group row as a whole is clicked, so that the opener icon (+/- icon) must be clicked.

Are you saying clicking on that icon doesn't work?

If so, first check that your DOCTYPE is correct (see FAQ), that you have no external CSS (see FAQ), and make sure you can reproduce the problem on more than one machine.
