[jboss-user] [JBoss Seam] - Re: DRY Edit pages

The problem of changing db / entity metadata requiring a second change in the ui is not new and has been around for ever and predates java.

However to make life easier just make a utility f(x) that will grab the entity and check for the field and see if it has a Hibernate annotation or your own custom annotation and get the appropriate metadata (length / precision etc  ) you need and then use it.

Maxlength and size both support EL. So you can do a size="#{fieldMetadata.sizeCalc('foo.class', 'field'}" instead of a " size="2".

You can use custom facelets to do the same thing.
