     [ https://jira.jboss.org/jira/browse/JBSEAM-4172?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Roth closed JBSEAM-4172.
-------------------------------

    Fix Version/s: 2.2.0.CR1
       Resolution: Done


Added "required" attribute to validator tag. See documentation. Passes the value through to the validator. Validate name example modified to show this behavior.

> Suppose such form elements:
> <s:decorate template="/template/form_item.xhtml">
>   <ui:define name="label">
>     <h:outputText value="#{messages.old_password}" />
>   </ui:define>
>   <h:inputSecret id="old_password" value="#{updateProfileAction.password}" />
> </s:decorate>
> <s:decorate template="/template/form_item.xhtml">
>   <ui:define name="label">
>     <h:outputText value="#{messages.new_password}" />
>   </ui:define>
>   <h:inputSecret id="new_password" value="#{updateProfileAction.passwordNew}">
>     <s:validateEquality for="old_password" messageId="new_password_is_equal_to_old" operator="not_equal" />
>   </h:inputSecret>
> </s:decorate>
> <s:decorate template="/template/form_item.xhtml">
>   <ui:define name="label">
>     <h:outputText value="#{messages.repeat_new_password}" />
>   </ui:define>
>   <h:inputSecret value="#{updateProfileAction.passwordNewRepeat}">
>       <s:validateEquality for="new_password" messageId="new_passwords_dont_match" />
>       <ui:remove>
>         This component is implicitly required (org.jboss.seam.ui.renderkit.EqualityValidationRendererBase:46 = evh.setRequired(true);)
>         It makes impossible to achieve such behavior:
>         1) If both password fields are blank then its ok - user doesn't want to change his old password.
>         2) If there is any text in one of the fields - check if values are equal and update password only if they are.
> </ui:remove>
>   </h:inputSecret>
> </s:decorate>
> At the moment validation fails for empty fields as they are required.
