Steve Roy commented on JBSEAM-1526:
-----------------------------------
I would imagine this is a very common problem in web projects. We've run into this problem as well in our web-based apps.
I would suggest this might be better addressed in the JSF spec rather than in Seam though.
> Support selective validation with a:region
> ------------------------------------------
>
> Key: JBSEAM-1526
> URL: https://jira.jboss.org/jira/browse/JBSEAM-1526
> Project: Seam
> Issue Type: Feature Request
> Components: JSF Controls
> Reporter: Christian Bauer
>
> In complex forms I'd like to be able to customize validation per region:
> <h:form>
> <a:region>
> <h:inputText value="#{foo.bar}"/>
> <a:region>
> <h:inputText value="#{bar.foo}"/>
> <a:commandButton action="#{bar.baz}"/>
> </a>
> <a:commandButton action="#{foo.baz}"/>
> </a>
> </h:form>
> If the nested button is pressed, I only want #{bar.foo} validated (there is an <s:validateAll> around it). If the outer button is pressed, I want both properties validated. I realize that this is a major issue regarding model updates, however, I don't need to update the model for any non-validated property because
> a) it is not decoded on the server anyway (? I don't understand the a:region docs)
> b) i don't need an updated model because my action doesn't expect it
> c) i don't need an updated model because i am re-rendering an area that doesn't expect it
