I am adding a template to an existing grid that's been working fine for a while. I keep getting an invalid template error but I don't see anything wrong with the template. I have other templates for other grids that work just fine and the code is very similar. Is there a good way to troubleshoot this type of problem? Perhaps a way to output a more detailed error message? The current invalid template error message only tells you that there is a problem and is not helpful in figuring out what the problem is.
