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
