Seam conversations and third party JSF components libs

[mgrouch]

What is the way to send conversation id with third-party libraries ajax requests. For example, Quipukit library comes with data table
pagination control which has ajaxed controls. Click on those controls
submits ajax request without conversation id and causes exception on
server side

java.lang.IllegalStateException: No active conversation context
at org.jboss.seam.core.Conversation.instance(Conversation.java:103)
at org.jboss.seam.faces.FacesManager.prepareBackswitch(FacesManager.java:236)
at org.jboss.seam.jsf.SeamPhaseListener.afterRender(SeamPhaseListener.java:505)
at org.jboss.seam.jsf.SeamPhaseListener.afterServletPhase(SeamPhaseListener.java:230)
at org.jboss.seam.jsf.SeamPhaseListener.afterPhase(SeamPhaseListener.java:184)

Is there workaround for it?
Thanks

I've made some progress with this issue by adding
page action

action="#{myBean.beginCall}"

<page xmlns="http://jboss.com/products/seam/pages"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.0.xsd"
 login-required="true"
 conversation-required="false"
 no-conversation-view-id="/home.xhtml"
 action="#{myBean.beginCall}">
 <!--
 <begin-conversation join="true"/>
 -->
</page>

and action in myBean

public String beginCall() {
 Lifecycle.beginCall();
 return null;
 }

java.lang.IllegalStateException: No active conversation context
now fixed and disappeared, requests are processed with correct response being rendered. However there are too many exceptions in the log.

java.lang.IllegalStateException: No phase id bound to current thread
at org.jboss.seam.contexts.PageContext.getPhaseId(PageContext.java:162)

Is this even the right approach?
Thanks

I've got rid of some exceptions by improving beginCall()

 if (!Contexts.isConversationContextActive()) {
 Lifecycle.beginCall();
 }
 if (!Contexts.isPageContextActive()) {
 FacesLifecycle.resumePage();
 }
 try {
 if (!Transaction.instance().isActiveOrMarkedRollback()) {
 Transaction.instance().begin();
 }
 }
 catch (Exception ex) {
 throw new IllegalStateException("Could not start transaction", ex);
 }

I still have this exception which I haven't figured out how to get rid of:

Take a look org.jboss.seam.ui.resource.StyleResource.getResource() for how to properly run your code inside the Seam lifecycle.

Hmm. Looking at that doesn't help me (or I do not undersand something).
I think now I can explain my problem better.

When quipukit submits its own ajax requests (like during the click on pagination control) all Seam contexts are not available on server side.
What would be a workaround to fix it? I do not have the source of quipukit
as it is proprietary and it works with Seam 1.2.1.GA. The problem is only with Seam 2.0.Beta1.

I appreciate any ideas. I'm stuck with this problem.

Still no luck trying to resolve this. Any help is very much appreciated.
Thanks
