This is a quick note about messages in JSF. I like to place my error messages next to the label for a field rather than after the field. Normally this means that the label is before the field and therefore the message output command will typically be before field. This causes a warning log message to be output with the following format:

WARNING: Unable to find component with ID 'foo' in view.

but doesn't seem to cause any adverse effects. It would be nice if JSF catered for this situation as I can't be the only person that wants to put the message before the field.
