Jacob Orshalick commented on RF-1133:
-------------------------------------
I encountered this issue and implemented a workaround using a Seam interceptor that is described here:

Hope it helps.

> Key: RF-1133
> URL: http://jira.jboss.com/jira/browse/RF-1133
> Project: RichFaces
> Issue Type: Bug
> Affects Versions: 3.1.1
> Reporter: henrik lindberg
> Assigned To: Nick Belaevski
> Priority: Critical
> Fix For: 3.2.0
>

> When the datamodel for a rich:dataTable is replaced with a new model the rich:datascroller still remembers its old page index.
> Now, in order to make it work, I have to look up the UIData and set the index to 0 when I change the datamodel.
> I would expect it to either be set to 0, or to the value of "first" attribute in the rich:dataTable when its model is changed.
> This problem is blocking me from releasing my application - I have *many* affected datascrollers and doing the following for all of them would not be fun...
> // how I reset the first value - perhaps there are beter ways to do this
> String id = "spaceForm:content_list";
> UIComponent comp = FacesContext.getCurrentInstance().getViewRoot().findComponent( id );
> if(comp == null)
> throw new IllegalArgumentException("Can not find component with id = '"+id+"'");
> if(!(comp instanceof UIData))
> throw new IllegalArgumentException("Id does not refer to a UIData instance");
> UIData uidata = (UIData)comp;
> uidata.setFirst(0);
