Re: Problem with Tiles an ActionForms

[Laurie Harper <la...@holoweb.net>]

I don't know why setting validate=true would change how Tiles constructs 
the page, but a couple of observations which might help:

- your action mapping doesn't have an 'input' attribute defined to tell 
Struts what to display if validation fails

- your form bean extends ActionForm, not ValidatorActionForm. For 
validate=true to work correctly I think you need to extend the latter (I 
may be wrong there; it may not matter if you're not using XML-based 
validation).

Sorry I can't be more helpful; other than that, what you have looks 
reasonable to me. Have you tried enabling debug logging in Struts and 
comparing the log output for the two scenarios?
