[jira] [Created] (TAP5-2587) Grid component zero division on rowsPerPage

Michail Almyros created TAP5-2587:
-------------------------------------

             Summary: Grid component zero division on rowsPerPage
                 Key: TAP5-2587
                 URL: https://issues.apache.org/jira/browse/TAP5-2587
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.4.3, 5.4.2, 5.4.1
            Reporter: Michail Almyros


When the component will try to setup the data source there is a chance that the rowsPerPage parameter hasn't been initialised yet and this can lead to division by zero.

Simply adding an additional check for the rowsPerPage parameter will fix the issue.

Change to
{code:java}
// Method setupDataSource, line 499
if (availableRows == 0 || rowsPerPage == 0)
            return;
{code}
