> Project: Tapestry
> Issue Type: Bug
> Components: Core Components

> Environment: Debian Lenny, Sun JDK 1.6, Jetty, Tapestry 5.0.6

> I have a grid defined with rowsPerPage = 2. When there are 3 elements in the GridDataSource, the user clicks the "2" link to display page 2. (So that there is only one element displaying). The user clicks an action link that has the following event handler defined:
> public ListAccount onActionFromDel( Integer prmRId ) {
> _DAO.delByRId(prmRId);
> return( _listAccount );
> }
> (ListAccount is the current page class).
> As the Grid attempts to re-render itself, it calls getAvailableRows() on the GridDataSource, and getAvailableRows() correctly returns 2.
> The Grid should automatically go to page 1 since there are only 2 rows available and rowsPerPage is set to 2. However, instead, the Grid calls prepare() with firstResult = 2 and lastResult = 1. After this, the Grid calls getRowValue() with a negative value.
> Note that the problem goes away if I add a line to the event handler:
> public ListAccount onActionFromDel( Integer prmRId ) {
> _DAO.delByRId(prmRId);
> _listAccount._actList.setCurrentPage( 1 ); <------ this line solves the problem
> return( _listAccount );
> }
> But I don't believe this should be necessary.
> Thanks,
> Andy
