Hi, a Rails newbie here.

I have an AJAX form which, upon submission, updates another part of  
the page using AJAX (with an .rjs). I would like to catch illegal  
submissions and display their corresponding error messages using AJAX.  
However, I am having trouble retrieving the error messages as they  
seem to be cleared at some stage - is there any way of passing them  
through, in params[] possibly? I would rather do my validations with  
Rails than JavaScript (which has been suggested elsewhere).

Any help would be much appreciated.
