Subject RE: Struts Validator: form value1 < form value2
Date Thu, 22 Jun 2006 15:22:55 GMT
Extra parenthesis solved my problem.  Thanks for the help.  Below is the
validation that I added to field 1.  I left it out of field2 since I did
not want to see redundant error messages.

(
  (
	(field2 == null)
	or
	((field2 != null) and (*this* == null))
  )
  or 
  (
	((field2 != null) and (*this* != null))
	and
	(*this* <= field2)
  )
)

The struts validator guide says you can only join 2 values with and or
or. I'm guessing that means you either have to put in a lot more
parentheses or that you can't use and or or more than once. I would
first try parenthesizing everything.
