Hi I have a problem with conditional validation. Currently i am working with struts 1.1 - because of its WSAD support but i am thinking of migrating to the newest one. My problem is that on my jsp page i have 2 radio buttons: <html:radio name="viewBean" property="documentIdentity" value="dowod"/> <html:radio name="viewBean" property="documentIdentity" value="paszport"/> I am using struts validator and in my validation.xml i want to have passportNumber property validated IF AND ONLY IF documentIdentity equals paszport. More, i want to have it validated with other validators too. I need something like: <field property="passportNumber" depends="requiredif,mask" page="1"> <var> <var-name>field[0]</var-name> <var-value>documentIdentity</var-value> </var> <var> <var-name>fieldTest[0]</var-name> <var-value>EQUAL</var-value> </var> <var> <var-name>fieldValue[0]</var-name> <var-value>paszport</var-value> </var> <var> <var-name>mask</var-name> <var-value>${passportNumberMask}</var-value> </var> </field> So if documentIdentity.equals paszport, passportNumber is required and needs to be validated against mask validator. If doucmentIdentity eqauls dowod, i do not wanna to validate passportNumber at all. Can struts validator satisfy my requirements? Can struts 1.1 validator satisfy it?? I have spent a lot of time on struts mailing list trying to find an answer for my problem but i haven't found anything special. Maybe solution presented in http://marc.theaimsgroup.com/?l=struts-user&m=113029818225923&w=2 is suggested in Struts. Can anyone help me.
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.
