HtmlTableRendererBase and ResultSetDataModel

[Pichai Ongvasith]

Hello,

I tried to use a ResultSetDataModel as the data model for <t:dataTable>, 
with myfaces1.1.1. It turns out that the result never shows up in the table.
My guess is that this might be related to Jira issue MYFACES-278.
Looking into the source code, I guess 
HtmlTableRendererBase.encodeInnerHtml is doing the job to render the 
result set.
this is the excerpt of relevant code.
       int first = uiData.getFirst();
       int rows = uiData.getRows();
       int rowCount = uiData.getRowCount();
       if (rows <= 0)
       {
           rows = rowCount - first;
       }
       int last = first + rows;
       if (last > rowCount)
           last = rowCount;

       for (int i = first; i < last; i++)
       {           
            // render
       }

If that's true, the method might be mishandling the uiData.getRowCount.
The implementation of ResultSetDataModel.getRowCount in myfaces1.1.1 
always return -1, which is valid when the row count is unknown at the 
time. So before the rendering loop, last is always -1, and nothing would 
be rendered.

Or am I missing something here?
