I have a form from displaying a number of items. The form also displays some validation problems. The user can correct these problems by editing items by clicking on a link and is then forwarded to another page using setResponsePage(...). After editing, the eidt page forwards back to the same instance of the form page.
Now I want to do validation as soon as this happens and add messages to the page using info(), warn(), and error(). Nevertheless, I cannot get this to work. I tried overriding onAttach() and onBeforeRender() but apparently my messages are getting lost. What would be the correct way to trigger this validation? Apparently I am too early in the lifecycle and the messages are being reset after I set them.
Cheers
Erik
