Hi
Thanks for all answers. Finally i created 2 new validators: skipNextIf and
gotoNextIf.
They both test some expression which is passed in var-value parameter and if
the expression is evaluated to true,
skipNextIf return false and gotoNextIf return true. As you can imagine, i do
not add any entries to Errors in these validators .
They just work only as some kind of gateway which can break the the
validation chain for a property.

You could write a custom validator which would read the value of the
documentIdentity. Then,
If
documentIdentity != "pazport", return true
else
-- Run your mask validation for passport number --
To do the mask validation, from your class, consult this:
http://struts.apache.org/struts-action/struts-core/apidocs/index.html
Look for a method: validateMask()

Unfortunately the validation framework doesn't support this requirement
directly; when you say depends="requiredif,mask", this is taken to mean
'the field is valid if it passed the requiredif test AND it passes the
mask test'. There's no way to have a requiredif/validwhen rule control
whether another rule is applied.
The message you referenced in the archives looks like a good starting
point to achieve what you want. Essentially, you will need to write your
own validation rule. That message looks like it details a reasonably
flexible basis for doing so.
