Exceptions in views hard to catch

Reported by pedz | February 21st, 2009 @ 02:54 AM | in 3.0.2

I had a ticket open in the old Rails bug system about this along with a patch. That patch no longer works.

I have a couple of questions / concerns.

First, if a template encounters an exception during "compile" time, the original exception is caught and wrapped in a TemplateError exception. Thats fine but if an exception occurs during "run" time, the exception is also caught and also wrapped in a TemplateError. It would be nice if those two wrappers were different.

Second, I set a catch for a particular exception but if that exception happens while in a view, then the view code catches it and wraps it. When it gets to action controller, now my exception handler is not used because it looks like a TemplateError exception.

Third, the second item above would not be too bad if there was a defined way to catch a TemplateError exception (or any exception), examine it, and if I don't want to really catch it, return "false" or something like that from my exception handler and have it be caught by the default handlers. (I guess calling rescue_action_without_handler would work but is that "stable"?)

I would not mind working on a patch for all this but it gets frustrating submitting patches for the same issue over and over again.
