Bob Corcoran commented on RF-4064:
----------------------------------
At the bottom of this message is the source for the entire page where the links are breaking when we set required="true" on an inputText and/or an inputTextarea. Sorry, it didn't format well when I copied it in. I should add that whether I use an a4j command link or an html command link I see the same behavior.
Here is a summary of the input fields and the links that work and don't work:
These links break:
---------------------------------------------------------------------------------------------------------
<a4j:commandLink action="#{profileGroupBean.loadPersonalForums()}">
<h:outputText value="Groups"/>
</a4j:commandLink>
<a4j:commandLink styleClass="link" rendered="#{profileGroupBean.privateView}" action="#{groupDetailsBean.setFilter (groupDetailsBean.FILTER_NONE)}">
<h:outputText value="#{groupDetailsBean.forum.forumMembers.size()} member(s)"/>
</a4j:commandLink>
<a4j:commandLink styleClass="add-link" action="#{groupDiscussionBean.setDiscussionId(discussion.id)}">
<h:outputText value="#{discussion.topic}"/>
</a4j:commandLink>
---------------------------------------------------------------------------------------------------------------------------------------------------------
This link does not break
-----------------------------------------------------------------------------------------------------------------------------------------------------------
<a4j:commandLink id="authorLink" rendered="#{not empty discussion.rootMessage.creator.user.person}"
action="#{profileGroupBean.setForumMember(discussion.rootMessage.creator)}"
oncomplete="Richfaces.showModalPanel('authorViewPanel');"
reRender="authorAjaxPanel"
title="Author">
<h:graphicImage rendered="#{profileManager.hasImage(discussion.rootMessage.creator.user.personId)}"
height="16" styleClass="photo" alt="Photo"
url="servlet/imageServer?personId=#{discussion.rootMessage.creator.user.personId}&height=16"></h:graphicImage>
<h:graphicImage rendered="#{!profileManager.hasImage(discussion.rootMessage.creator.user.personId)}"
height="16" styleClass="photo" alt="Photo"
url="http://espnfield/employees/Photo?employee_id=#{discussion.rootMessage.creator.user.personId}&width=16&height=16"></h:graphicImage>
<h:outputText value=" #{discussion.rootMessage.creator.user.person.firstName} #{discussion.rootMessage.creator.user.person.lastName}" />
</a4j:commandLink>
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Here is one of the input widgets
<h:inputText id="topic" size="70" maxlength="70" required="true"
value="#{groupDetailsBean.newTopic}" >
<f:validateLength maximum="70"></f:validateLength>
</h:inputText>

> Problem with a4j:commandLink

> Key: RF-4064
> URL: https://jira.jboss.org/jira/browse/RF-4064
> Project: RichFaces
> Issue Type: Bug
> Environment: Windows
> Reporter: Bob Corcoran

> We have a page with a few a4j:commandLinks as well as an h:inputText and h:inputTextarea, among other markup. It works fine until we add the attribute required="true" to either the inputText or InputTextarea. When we add the required="true" to either the inputText or InputTextarea, one of the a4j:commandLinks's (further up on the page) breaks. It still renders fine, but the method on the backing bean (in this case a SEAM stateful bean) is not called, because the link does not fire. What's even more odd is that the remaining a4j:commandLinks on the page continue to work according to specs. These links are contained in separate rich:column tags.
