[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3676) s:validateEquality doesn't work in s:decorate

[Ingo Jobling (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBSEAM-3676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12439389#action_12439389 ] 

Ingo Jobling commented on JBSEAM-3676:
--------------------------------------

Problem is that EqualityValidator line 74 cannot find the component

UIComponent otherComponent = component.findComponent(forId);

As per JSF 1.2 API, findComponent will search up the parents of this component. If a NamingContainer is encountered, it will be the base for the search.

Since s:decorate implements the NamingContainer interface, findComponent fails to locate the Id, and returns null, resulting in the exception seen above.

A workaround is to specifiy the full client id, with a leading ":", like this:

<s:validateEquality for=":#{rich:clientId('password')}" />

This results in something similiar to for=":user:j_id174:password"

> Hello,
> I have dicovered the s:validateEquality control. It's perfect for email and password double check.
> I have a problem, if the tags are in a s:decorate template... The validation failed with this exception:
> Caused by: java.lang.IllegalStateException: forId must reference an EditableValueHolder ("input") component
> 	at org.jboss.seam.ui.validator.EqualityValidator$OtherComponent.<init>(EqualityValidator.java:168)
> 	at org.jboss.seam.ui.validator.EqualityValidator.validate(EqualityValidator.java:74)
> 	at org.richfaces.component.html.HtmlInputText.validateValue(HtmlInputText.java:35)
> 	at javax.faces.component.UIInput.validate(UIInput.java:867)
> This code is working:
> 	<h:inputText id="emailInput" value="#{classicUser.email}" required="true">
> 		<s:validate />
> 	</h:inputText>
>         <h:inputText id="emailInputVerification">
> 		<s:validateEquality message="Mails must be identical" for="emailInput" />
> 	</h:inputText>
> This code is not working
