RenderPhaseDataScrollerVisitor does not work with Tomahawk AliasBean Component
------------------------------------------------------------------------------

                 Key: RF-7922
                 URL: https://jira.jboss.org/jira/browse/RF-7922
             Project: RichFaces
          Issue Type: Bug
          Components: component-tables
    Affects Versions: 3.3.1
            Reporter: Mirko Sertic


The default RenderPhaseDataScrollerVisitor does not work with the Tomahawk AliasBean Component. 

Basically, it is invoked by a PhaseListener. It recomputes the model size of the bound UIData and does some other stuff. And here starts the problem. When i use a t:aliasBean to define the datamodel for the UIData, it does not work, as the aliasBean component sets and unsets the alias during its lifecycle processing. 

Now, the RenderPhaseDataScrollerVisitor is invoked before the aliasBean can do its job. An empty DataModel is created and put to the modelmap. Later, aliasBean does it work, and the UIData tries to render. Instead of asking again for the datamodel, it uses the empty model from the modelmap, and thus the table is empty.

I know that it is somehow difficult to support every component, but at least it should be supported to disable the RenderPhaseDataScrollerVisitor in some way, or provide my own implementation for it
