[Erp5-dev] Validation of multiple fields on one form

[Mikolaj Antoszkiewicz]

Hello,

I've just came across such an issue:

I'm trying to validate if a given user (actually a pair First+Last Name) 
was already saved (used) in the system.

Well, the problem is that I'd like to check both fields at the same 
time, but the validating script gets only a field value from the field 
it's attached to.
I've used the Request object passed also to the validating script, to 
get both last and first name values, but it looks a bit ugly.

Is there any 'nicer' way of doing such a validation?
