thanks Niall,
I've had a look at the examples and I'm not sure they demonstrate what I
need. The examples all seem to be simple boolean expressions e.g.
<field property="address1" depends="validwhen">
<arg key="validWhenForm.address1" />
<var>
<var-name>test</var-name>
<var-value>( (*this* != null) or
( (address2 == null) and
( (city == null) and
(zip == null) )))</var-value>
</var>
</field>
I have a select (fieldB) that determines the type of fieldA. So the
validation to operate on fieldA depends on the value of fieldB.
<field property="fieldA" depends="validwhen,required">
<arg key="form.fieldA" />
<var>
<var-name>test</var-name>
<var-value>
((fieldB == 'java.lang.Integer') && validateInteger(fieldA))
|| ((fieldB == 'java.lang.Float') && validateFloat(fieldA))
|| ((fieldB == 'java.util.Date') && validateDate(fieldA))
etc....
</var>
</field>
is this possible? I'm thinking not, so a custom validation method is
probably what I need.
cheers

Hi,
I have two fields in a form. I believe the validwhen rule executes a
specific rule (e.g. required) on field a based upon the value of field
b. The situation I have is that I need to execute different validations
on field a determined by the value of field b.
Yes - theres a validwhen example page in the struts-examples webapp in
the binary distro (see the validation module).
Is this possible client side with the latest validator framework
(1.3.1)? or will I have to implement this functionality in the validate
method of the form (server side)?
validwhen is server side only.
Its also a custom Struts validator - not part of Commons Validator so
in that respect the version of Commons Validator is not relevant.
