question about a4j:region

[ziphyre]

Hi,

I'm using richfaces with seam (2.0.2) and I think I'm missing some point.
I got a a4j:commandLink seperated with his own form (and not nested in any other form) linked to a simple method who actually just change a string property, it has no reRender, nor action attribute:

<h:form>
 <a4j:region>
 <a4j:commandLink styleClass="tabHead life" value="Hot Spot"
 actionListener="#{panelManager.switchLeftPanelVisibility}"
 onclick="$('buddiesPanel').hide();$('lifePanel').show();"/>
 </a4j:region>
</h:form>

But every time I click the link, I see all the database interaction log that would occur on a page reload on my eclipse console...

16:44:23,236 INFO [STDOUT] Hibernate:
 select
 message0_.id as id48_,
 message0_.messageRead as messageR2_48_,
 message0_.messageText as messageT3_48_,
 message0_.subject as subject48_,
 message0_.fromUser as fromUser48_,
 message0_.conversationId as conversa5_48_,
 message0_.toUser as toUser48_,
 message0_.sentDate as sentDate48_,
 message0_.replyTo as replyTo48_
 from
 Message message0_
 where
 message0_.toUser=?
 order by
 message0_.sentDate DESC

...... etc etc.

Since this request has nothing to do with db, is in his own form, and seperated with a4j:region, I would except no db interaction at all, but obviously I didn't quite get the inner workings of a ajax request. So I would be very happy if you could explain me what's going on...

Thanks...


PS: since a4j:commandLink is the only element in that specific form, a4j:region is unnecessary, isn't it?

please show full page content.

It's very crowded, I'll try to simplify without breaking the structure...

<div id="leftColumn" class="Column"><!-- leftColumn -->
 <h:form>
 <a4j:region>
 <a4j:commandLink styleClass="tabHead life" value="Hot Spot"
 actionListener="#{panelManager.switchLeftPanelVisibility}"
 onclick="$('buddiesPanel').hide();$('lifePanel').show();"/>
 <a4j:commandLink styleClass="tabHead buddy" value="People"
 actionListener="#{panelManager.switchLeftPanelVisibility}"
 onclick="$('lifePanel').hide();$('buddiesPanel').show();"/>
 </a4j:region>
 </h:form>

 <a4j:outputPanel id="lifePanel" layout="block" style="display:#{panelManager.hotspotDisplay}">
 <div id="lifePanelContainer">
 <h:form id="hotspotForm">
 <h1 id="lOne" class="accordion_toggle first mail">Mesaj Kutum</h1>
 <a4j:outputPanel layout="block" id="mailList" styleClass="accordion_content mail">
 <rich:datascroller styleClass="scroller" id="latestMessageScroller"

 </rich:datascroller>
 <rich:dataTable id="messages" var="msg" value="#{messageList}" rows="2">

 <h4>#{msg.from.firstName} #{msg.from.lastName}</h4>
 <a4j:commandLink styleClass="#{msg.read?'read':''}"

 value="#{empty msg.subject ? '...' : msg.subject}" />
 ...

 <div class="clear dotted"> </div>
 </rich:column>

Hi,

I know that this post is a long time, but the needs remain.

succeeded or someone suggests solution to this problem that persists?

[ziphyre]

nope, the question still remains on my part. I just switched to other parts of the development and left the optimization to a later period...
