Missing 'rows' attribute on component 'xxx'
Hello!
Playing with RC6 I got this exception...

Looking into the code:
219 public int getPageIndex(UIData uiData) {
220 //xxxx nick -> alex - suppose this.getRows() would be better here
221 int rows = getRows(uiData);
222 if (0 == rows) {
223 throw new FacesException("Missing 'rows' attribute on component '"
224 + uiData.getId() + "'");
225 }
...
The situation is that rich:datascroller is inside a a4j:repeat and all it inside
<rich:tabPanel switchType="ajax">.
so when I switch the tab back - the exception happens since it couldn't find a rows (?).
I understand that you have the release scheduled in a few days, but will we see bugfix release or should wait for 3.2?
thank you.
