2807	"allow overriding default ""This field is required."" text"	wildfire@…	Adrian Holovaty	"Hi,

If you create a cutom form, you can specify the isRequired property. If it is set to True and the field is not submitted, the error raised will be a (very) generic ""This field is required."".

It would be useful if you could override the return validationerror somehow.

One possibility is the make isRequired a 'ready-made' validator rather than a property since all ready-made validators have an error_message that can be passed in if validation fails.

It would also remove the special-case handling of 'isRequired' and make it just another validator. Being generic can be good - especially if you get to throw in a feature for free :-)"	defect	closed	Validators		normal	wontfix			Unreviewed	0	0	0	0	0	0
