> Project: Tapestry

> Components: Core Components

>
> 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.
