a4j:support action is not called

[faupel]

Hi,

I have a h:selectOneMenu that refreshes the content of a a4j:repeat. That works fine. When I add a4j:support to the h:selectOneRadio on the a4j:repeat, an ajax request is sent, but the action is not called. I have no validation on that page and the converters work well. I don't use ajax4jsf very long so it could be that I misunderstood something.Thank you in advance.

Maximilian

Hi Maximilian,

Please take a look: http://community.jboss.org/wiki/CommonAjaxRequestsProblems#actionNotCalled

Hi Nick,

thank you for your answer, but I already know that. I read about 100 posts and tried everything. I have an output for faces messages in my template and I did override the equals and hashCode methods in my entities.

That's what I put in my template:

a4j:outputPanel ajaxRendered="true">

    <h:messages/>

</a4j:outputPanel>

I also put a <a4j:log /> tag on my page, but I can only see, that an ajax request is sent and I can't see any errors.

Thanks

Maxi

OK, so we can exclude the most frequent coding issues. Can you please check this issue: https://issues.jboss.org/browse/RF-3314 to see if it's applicable to your case?

Two of my entities are in seams page scope. If I change that to conversation or session scope, the problem is still the same.

Hi Nick,

I wrote a little example to reproduce the error. I hope you can see what I made wrong.
