[jboss-user] [JBoss Seam] - Re: Customize validation messages

[hamtho2]

Norman,

can you please give a little bit more detail about using your code. Simply creating the class and using the s:input-tag leads to an exception. Sorry - but I haven´t done anything in the tag-libraries yet, so I´m not so familiar how to add a new Tag.

I get the following exception:

com.sun.facelets.tag.TagException: /WEB-INF/pages/registerUser/userDataForm.xhtml @53,142 <s:input> Tag Library supports namespace: http://jboss.com/products/seam/taglib, but no tag was defined for na

Thanks a lot.

By the way: I think that would be a great benefit for seam to have this component, so why don´t you make it a core-feature? I think it´s a very common and important thing to display user-friendly validation-messages. You should definately think about it
