h:outputLink navigation sometimes does not work

Question

I have a navigation define from one page to another like this.

<h:outputLink id="idLink"  value="Page1.seam" >
    <f:param name="m" value="n103" />
    <f:param name="mss" value="110" />
<h:outputText value="Return to Page 1" />
<a4j:support event="onclick" action="#{beanName.action}" limitToList="true" ignoreDupResponses="true" eventsQueue="que" ajaxSingle="true" immediate="true">
</a4j:support>
</h:outputLink>

The problem is there are sometimes that the view isn't changing to Page1.seam and remain in Page2.seam. Is there anyone who knows better ? Help will be greatly appreciated. Thanks.

What do you do in beanName.action? Post some code. Do you get any error or logs when it fails? Check the action in your browser. Is he doing a post. You can check with firebug net section and see if and what post is performed when it fails — roel, Jun 05 '12 at 09:12
@roel - ill look for an error, but this happens at very low chance, so ill further investigate. — Ellie Fabrero, Jun 05 '12 at 09:25

This construct makes no sense. Make it a normal link

<h:outputLink value="Page1.seam">
    <f:param name="m" value="n103" />
    <f:param name="mss" value="110" />
    <h:outputText value="Return to Page 1" />
</h:outputLink>

and to invoke an action on opening of the page, use <f:event type="preRenderView"> in the target view instead.

<f:event type="preRenderView" listener="#{beanName.action}" />

by the way i'm still using JSF 1.2 so there is no f:event, what do you think is a better alternative for this. thanks :) – Ellie Fabrero Jun 06 '12 at 05:32
Ah thus you also don't have a `` to set the parameters. Use the bean's constructor or `@PostConstruct` instead. – BalusC Jun 06 '12 at 12:14
I'll try `@PostConstruct`instead. Thank you very much. :) – Ellie Fabrero Jun 07 '12 at 00:33
@BalusC Can you please elaborate the reason when you say, `This construct makes no sense. Make it a normal link`. Why do you say so? – Vikas V Sep 09 '13 at 16:47
@Vikas: OP tried to send an idempotent request using ajax. This just doesn't make sense. – BalusC Sep 09 '13 at 16:51
