datascroller page not reset if datascroller not rendered, so data grid is empty 
--------------------------------------------------------------------------------

                 Key: RF-11254
                 URL: https://issues.jboss.org/browse/RF-11254
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-tables
    Affects Versions: 4.0.0.Final
            Reporter: u j


RichFaces 4 resets correctly the current page to 1, if the model of the associated datagrid is reassigned,
but this happens only if the rendered attribute of the datascroller is true.
That is:
- grid with > 1 page
- set page 2 with datascroller
- do some action which produces a new model with only 1 page
- rendered attribute of datascroller is dynamic so it yields false if only one page (workaround because renderIfSinglePage does not work :-)
-> data grid is empty instead of showing the content, because page is not reset to 1
Binding the page attribute to a bean property and setting it to 1 doesn't help either.
Code:
<rich:dataScroller rendered="#{fn:length(bean.result) > 6}" />
