Aladdin El-Nattar commented on RF-1133:
---------------------------------------
Got around it by doing this:
rich:datascroller id="pagination-scroller" for="contents-table"
renderIfSinglePage="false"
maxPages="20" page="#{action.contents.pageNumber}">
Setting pageNumber to 1 in the backing bean works in 3.2.1.GA.
> rich:datascroller does not reset when data model is changed
> -----------------------------------------------------------

> Key: RF-1133
> URL: https://jira.jboss.org/jira/browse/RF-1133
> Project: RichFaces
> Issue Type: Bug
> Components: docs updated
> Affects Versions: 3.1.1
> Reporter: henrik lindberg
> Assignee: Tsikhon Kuprevich
> 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);
