I'm reading earlier posts on the selection listener and trying figure out what
exactly
is happening with it. I'm looking at
<f:facet name="document">
<h:panelGroup>
<h:commandLink immediate="true" styleClass="document"
actionListener="#{t.setNodeSelected}" rendered="#{!t.nodeSelected}">
<h:graphicImage value="/images/document.png" border="0"/>
<h:outputText value="#{node.description}"/>
<f:param name="docNum" value="#{node.identifier}"/>
</h:commandLink>
<h:commandLink immediate="true" styleClass="documentSelected"
actionListener="#{t.setNodeSelected}" rendered="#{t.nodeSelected}">
<h:graphicImage value="/images/document.png" border="0"/>
<h:outputText value="#{node.description}"/>
<f:param name="docNum" value="#{node.identifier}"/>
</h:commandLink>
</h:panelGroup>
</f:facet>
This what I see is happening:
When someone clicks the first command link, the 't' is just internally setting
a
variable so t.nodeSelected returns true. When page re-rendered the second link
is
displayed, which has a style that does something to indicate the node is
selected.
I'd like to continue being a lazy programmer and not have to type the content
of my
command link twice. Is there a way the above can be refactored so it only needs
one
command link? For instance in jstl I'd do:
<c:if test="${t.nodeSelected}">
<h:commandLink immediate="true" styleClass="documentSelected"
actionListener="#{t.setNodeSelected}" rendered="#{t.nodeSelected}">
</c:if>
<c:if test="${!t.nodeSelected}">
<h:commandLink immediate="true" styleClass="document"
actionListener="#{t.setNodeSelected}" rendered="#{!t.nodeSelected}">
</c:if>
<h:graphicImage value="/images/document.png" border="0"/>
<h:outputText value="#{node.description}"/>
<f:param name="docNum" value="#{node.identifier}"/>
</h:commandLink>
I'm not clear on mixing jstl and jsf. Is this something works or is there a
"JSF" way
to do this?
And what is the current tree way in
"Of course you
can always configure it to behave exactly the same as the current tree
if that is your wish "
of doing selection?
