[ http://issues.apache.org/jira/browse/TAPESTRY-369?page=all ]
Howard M. Lewis Ship resolved TAPESTRY-369:
-------------------------------------------
Resolution: Invalid
Working my problem a bit more, I found that by making the validaton delegate
persistent AND by keeping a seperate delegate for each form (that is, each page
in my multi-page wizard) I was able to get the exact behavior I wanted.
> Allow update of invalid form submit data

> Key: TAPESTRY-369
> URL: http://issues.apache.org/jira/browse/TAPESTRY-369
> Project: Tapestry
> Type: New Feature
> Components: Framework
> Versions: 4.0
> Reporter: Howard M. Lewis Ship
> Fix For: 4.0
>
> The current form element components (TextField, ValidField, etc.) that
> support validation will not update bound properties if there is a validation
> error.
> This is not always desirable.
> When building a multi-page wizard, you will often allow the user to move
> backwards and forwards through the wizard.
> It is disconcerting to move backwards and then forwards and NOT see a value
> for a field at all, just because it failed some validation constraints.
> Now, ideally, we should be able to come back to the page and have those
> fields decorated and errors marked ... but that is well beyond the
> capabilities of the current system.
> Hm. An interesting idea; the validation delegate could track component
> addresses (page name + id path) and corresponding names. It could then
> *restore* names, even on a subsequent render of an otherwise fresh page. A
> wizard would have a seperate delegate for each page in the wizard and the
> wizard would persist between requests.
