we are doing some first steps with Richfaces und especially the ScrollableDataTable.
We observed that using Opera 9.26 seems to work not very well with
the ScrollableDataTable for the URL
* wrong rows are selected after scrolling
* no rows can be selected after scrolling
* no rerendering of the data after scrolling
So Opera is not really supported at the moment?
The support of Opera has a limited support. Limit includes scrollableDataTable and couple others from 80 existing components.
