> 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.
