thanks for the links gabriele
If I had to make a suggestion to the xwork committers I would suggest their
attribute configurations be a bit more specific
so instead of Login-validation.xml configured as
<validators>
...
<field name="user">
<field-validator type="visitor">
<param name="context">myContext</param>
<param name="appendPrefix">true</param>
</field-validator>
</field>
</validators>
where by magic incantation and algorithmic manipulation a user object would
reference field validations from
User-myContext-validation.xml
but is'nt this a bit more user-friendly..
<field name="user">
<field-validator type="visitor">
<param name="appendPrefix">true</param>
<param name="validator_filename">User-myContext-validation.xml</param>
</field-validator>
</field>
</validators>
this way a build / release manager can 'scan' the configuration file and
understand this validator must be in the distro
vs
waiting for the app to be deployed to production and unsuspecting op gets NPE
and then an email is posted to struts users
?
Thanks
Martin
