Yes, it seems caused by one unsolved issue
try please latest 3.3.3-SNAPSHOT.
Sorry for inconvenience, we now discussing the way to provide some official fix for that.
OK, thanks for your reply.
I also noticed that
rowClasses="row-even, row-odd" onRowMouseOver="prevRowStyle=this.className;this.className='row-over'" onRowMouseOut="this.className=prevRowStyle;"
does not work any more on extendedDataTable.
can't confirm. works ok for me at 3.3.2 SR1 and 3.3.3 snapshot.
