Hi Victor,
The key to the validator is that you can use multiple validations on the
one filed so you can combine things like less than and more than to give
you an open range etc. Another very powerful validation is 'valid when'
which allows you to set up complex checks that related to other fields
in your input etc.
Below is and example of the validation I use on a password changing form
where the confirmation must obviously be equal to the first entry of the
new password:
<form name="changePasswordForm">
<field property="passwordCurrent" depends="required">
<arg0 key="login.changePassword.currentPassword.label"/>
</field>
<field property="passwordNew" depends="required, minlength">
<arg0 key="login.changePassword.newPassword.label"/>
<arg1 name="minlength" key="${var:minlength}" resource="false"/>
<var><var-name>minlength</var-name><var-value>6</var-value></var>
</field>
<field property="passwordNewVerify" depends="validwhen">
<arg0 key="login.changePassword.newPwsNotEqual"/>
<var>
<var-name>test</var-name>
<var-value>(*this* == passwordNew)</var-value>
</var>
</field>
</form>
You can also see in the above example that passwordNew uses two
validations, required and minlength.
Hope that is of some help,
Bart.

Hi All,
I am using struts 1.2.7 and related Apache commons validator. I am using
validation.xml(whose rules are defined by validator-rules.xml
I need your insight of following issues
1.How do I validate open set data range,e,g (1,10) where 1 and 10 are
exclusive, current intRange/floatRange valiation only support close set data
range validation where bounds are included?
2.I find a limitation of common validator. i.e if I enter +1000 in a field that has
"integer" validation turned on, the common validator will complain about this
field is NOT integer something like that. Is this a bug?
3.A more complicated scenario, suppose that I need to validator two
fields,say x and y, the data range of y is dependent on x, e.g y must be the
range of [x,100], how do I make use of the common validator to do that? I know
I can write my customized plugged in validator to do it, but does validator
provides a default way to do it?
Many thanks in advance!
