JBossDeveloper

I have this working now. I edited the sample and rebuilt it with ANT and it works fine. It is a problem caused by Eclipse + MyEclipse plugin, and how I the projects setup. I had deployed jboss-seam.jar to the jboss-4.0.3/server/all/lib folder, and it needs to be in the applications .ejb3 jar file and only there.

Even i have been getting class cast exception , but i was surprised to note that i am getting CoreTable but unable to cast it to CoreTable variable.

ex : CoreTable corTab = (CoreTable) table where table is a UIComponent.

when i do table.getClass().getName() i get coretable object , but unable to cast this coreTable variable.

If you have encountered similar problem , please let me know how you have overcome this issue.

Thanks

Thanks Deniss,

Yes that works, except that I got a ClassCastException with this code:

UIXTable table = (UIXTable)Contexts.getEventContext().get("otherBean");

The 'otherBena' is defined as :

@Name("otherBean")
@Scope(org.jboss.seam.ScopeType.EVENT)
public class OtherBean {
 private UIXTable table;
 public setTable(UIXTable table)
 public UIXTable getTable()
 ...
}

Any idea ?

Thanks.

I am using Trinidad which is the same as ADF and it doesn't work , I wonder if u can tell me why

You can find working example of ADF faces with seam here

Nusa,

How did you solve your cast exception problem ??

Thanks

thanks , I can make ADF/Trinidad work forme , but not with ajax4jsf , when i am adding ajax4jsf.jar to my web-inf/lib the ADF components stop getting rendered...any idea?
Thanks again

I tried to get Trinidad to work with Seam/Facelets in a portlet (JSR-168) environment, short research releaved that there're problems with myfaces, facelets, jsf and portlet containers acting together. Most of the problems are how request, response and all sorts of different sessions are handled inside these frameworks.
For example, Myfaces makes a lot of assumptions, like casting general Request to implementation specific Requests etc, casting objects to MyFaces Impl classes with additional accessor (like setExternalContext), which don't hold when used along with other frameworks.

Thus adding one more (ajax4jsf) is likely to cause additional problems which can only made disappear by adding a lot of unmaintable wrappers and compatabily objects, which in turn make the whole more unstable.

Trinidad replaces some of the internal render components (like one for h:commandButton) and i guess ajax4jsf doesn't like that.

khaliq/Nusa,

I am also getting the cast exception. I was able to create a regular JSF managed bean and bind/cast to it just fine however, binding to a Seam component caused the cast exception:

Caused by: java.lang.ClassCastException: org.apache.myfaces.trinidad.component.core.data.CoreTable cannot be cast to org.apache.myfaces.trinidad.component.core.data.CoreTable

This is a simple classloading problem, and will be solved as soon as you take the time to learn and understand Java EE / J2EE classloading.

It has absolutely nothing to do with AOP. (??!)

And of course, Seam has a much more sophisticated feature than the ugly-ass and totally evil prerender() crap, ie. page actions. You will find this feature discussed extensively in the Seam documentation.

Ahem, sorry for being aggressive. I really need to learn how to not drink beer and answer forum posts. :-(

Gavin,

Yes a good advert for "don't drink and drive" ;) Apology accepted.

As stated in my post, it was only speculation and I was clearly wrong. While my assumption now appears rather naive (and, yes, I feel suitably embarrassed) please appreciate that many us on the forum are not yet well versed in the subtleties of AOP and classloading. In my class cast example I was able to bind to a regular managed bean but not via a Seam binding "because Seam used a different classloading mechanism to get the underlying class". Surely this IS quite subtle from a regular Seam programmers pov? Is this something that could be cleared up in the Seam reference, say introduce a section from a "Seam and the JEE environment" interaction perspective?

I would have taken the time to acquaint myself with the subtleties of JEE classloading but having read that documentation you'll know that stuff is not exactly 'light' reading hence my polite request for direction to the required material. RTFM is often a fair response but when the 'M' is something as big and vague as the JEE spec then some direction would be appreciated.

I agree with you that preprender does not work under Seam. I personally DO NOT want to be dealing with the raw JSF component instances. But let's face it, there will be a lot of people migrating to Seam from JSC who are used to having exactly that sort of experience of JSF programming. I only got onto to this because of the way in which the Trinidad built-in table selections work. Again, maybe something in the Seam reference could 'educate' people who may be used to other JSF programming models?

Anyway please accept my apologies if I upset you. I really appreciate the help you are giving myself and others on this forum. I will refrain from speculation from now on and I will now go away to read up on classloading and try to understand what's going on.

Best Regards,

Chris.
