While bringing an app to a recent build (0909) of struts 1.3 and
commons-validator-1.2.0, I notice the following related to ValidatorPlugIn:
When using multiple validation files, as in:
<plug-in clasname="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames"
value="/WEB-INF/lib/validator-rules.xml,/WEB-INF/moduleA/validationA.xml,/WEB-INF/moduleB/validationB.xml"/>
</plug-in>
I get in the tomcat console:
"WARN Overriding FormSet definition. Duplicate for locale: fr"
Result is that validation rules on moduleA are not working.
I suspect the message is because both validationA.xml and
validationB.xml have a <formset language="fr">
We used to be able to have one validationX.xml per module without
problems. (Having the bundle attribute since struts 1.2x made that even
better, so there could be one resource-file per module).
I see that now commons-validator 1.2 seems to change this. I fear that
without a fix I would have to go back to validations for 400 screens in
one single validationABCDEF...xml.
It looks like commons-validation 1.2 implementation builds a formset key
based on language, country and variant, but doesn't seem to merge
formsets any more.
If my analysis is correct, my suggestion would be
- to either have commons-validator continue to merge formsets for
backward compatibility, and/or,
- add a namespace or id parameter as in <formset id="moduleA"
language="fr">, if necessary to keep the "physical map" feature.
Using existing variant as namespace as in language="fr" country="ch"
variant="moduleA" would be an ugly hack, because I would have to specify
the locale as this for every jsp so that validation would still work.
Kind regards,
Wolfgang Gehner
