Grid component calls prepare() and getRowValue() with incorrect values
----------------------------------------------------------------------
Key: TAPESTRY-1901
URL: https://issues.apache.org/jira/browse/TAPESTRY-1901
Project: Tapestry
Issue Type: Bug
Components: Core Components
Affects Versions: 5.0.6
Environment: Debian Lenny, Sun JDK 1.6, Jetty, Tapestry 5.0.6
Reporter: Andy Huhn
I have a grid defined with rowsPerPage = 2. When there are 3 elements in the
GridDataSource, I 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).
The Grid calls getAvailableRows() on the GridDataSource, and getAvailableRows()
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
