3. Re: RF 4 and SWF
Hi Andy,
Please take a look at https://issues.jboss.org/browse/RFPL-1430 and for information related to SWF integration.
-
4. Re: RF 4 and SWF
Hey Lukáš,
thanks a lot for your reply! I've already read these links and I've used this information to make my config work. So it works for me perfectly to send an ajax-request, if I use an a4j:commandButton or an a4j:commandLink. But if I use a4j:functions or the like to send an ajax-request, Spring Web Flow gets a request, but couldn't detect an (ajax)event and so no transition is triggerd! So I'm not able to use "non-action"-Components like a drop-down-box to trigger a transition in swf.
And if you take a look at the example on https://issues.jboss.org/browse/RFPL-1430, there is never used a "non-action"-Component, but always a a4j:commandButton or a4j:commandLink, and that works for me also.

5. Re: RF 4 and SWF
I also have this same question? Can non-action components be used to load for example an selectOneMenu list? (partial page rendering)? And how?

7. Re: RF 4 and SWF
this works (when migrating from RF3 to RF4):
<h:selectOneMenu id="authType"
value="#{formBean.data['authType']}" styleClass="medium">
<f:selectItems value="#{formBean.selectItems['authTypes']}" />
<a4j:support id="authTypeChangeListener" action="authTypeChanged"
event="onchange" />
</h:selectOneMenu>
\/ \/ \/ \/ \/ \/ \/ \/ \/ \/
<a4j:jsFunction name="authTypeChangeTransitionTrigger" action="authTypeChanged" render="authTypeRegion" />
<h:selectOneMenu id="authType"
value="#{formBean.data['authType']}" styleClass="medium"
onchange="authTypeChangeTransitionTrigger()">
<f:selectItems value="#{formBean.selectItems['authTypes']}" />
</h:selectOneMenu>
