Indicate null property's name if NPE encountered in a Grid.

Key: TAPESTRY-2182
URL: https://issues.apache.org/jira/browse/TAPESTRY-2182
Project: Tapestry
Issue Type: Improvement
Components: Core Components
Affects Versions: 5.0.10
Reporter: Kevin Menard
Assignee: Kevin Menard
Fix For: 5.0 Next Release
When supplying a data source to a grid, if any instance in that data source has
a null value for any of the rendered properties, an NPE will be thrown.
Unfortunately, the error message does not indicate what the problematic
property is, so the developer has to use a hold-one-out strategy to debug the
problem. Indicating the column with the problem would help considerably. If
there were a way to meaningfully identify the row as well, that would be extra
nice.
