Seam doesn't play with ICEFaces

[hispeedsurfer]

My question is 'why this app work with pur Seam and MyFaces, but not with ICEFaces'

1. Abstract editor class

public abstract class AbstractEditorBean<T extends StandardEntity> extends AbstractEditorListeGemeinsames<T> implements Serializable {
 .
 .
 protected boolean neu;

 @Begin(nested=true, ifOutcome={"editor"})
 public String bearbeiten() {

 if (id == null) {
 addWarning(idError());
 return "main";
 }

 //Entity holen
 try {
 setEntity((T) em.find(getEntityClass(), Long.parseLong(id)));
 neu = false;
 if (getEntity() == null) throw new Exception();
 } catch (Exception ex) {
 addWarning(findenError());
 return null;
 }

 nachLaden();

 //Alles ok? Dann Editor anzeigen
 return "editor";
 }
 .
 .
 public boolean getNeu() {
 checkKorrekterAufruf();
 return neu;
 }
.
.
}

2. Measurement class

@Stateful
@Scope(ScopeType.CONVERSATION)
@Name("messmitteltypEditor")
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public class MessmitteltypEditorBean extends AbstractEditorBean<Messmitteltyp> implements MessmitteltypEditor {

 @In(required=false) @Out(required=false)
 private Messmitteltyp messmitteltyp;
 .
 .
}

3. All changes to web.xml, faces-config.xml and lib dirs for ICEFaces as descriped here:http://support.icesoft.com/jive/servlet/KbServlet/download/623-102-847/SeamKBArticle.txt

4. The xhtml pages:
a)messmittelTypListe.xhtml

Here the steps when I debug this app

1. current page: messketteListe.xhtml - click: bearbeiten
2. methode invoked: AbstractEditor.bearbeiten() -> set property neu=true -> outcome:"editor"
3. from outcome:"editor" -> messmitteltypEditor.xhtml
4. BANG. java.lang.NullPointerException (Exception getting value of property neu of base of type

So whats going wrong here? Without ICEFaces the app working perfectly. In ICEFaces Forum they gave no advice.

Thanks

Hello,

I believe this is an Icefaces issue: request parameters (maps) are not properly initialized (cf. PersistentFacesServlet).

Jerome.

Hello,

I think it's a bug like descriped here
http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3991677#3991677

Can it be?



Thanks
Andreas

[jerome_082006]

Yes, exactly, I had to face the same issue.

This might help:

Hi Jerome,

thank you for reply. I have tried to modify the PersistentFacesServlet.java as descriped. But in the icefaces.src.core package ELSetPropertiesRule.java is an error that getExpressionFactory() is undefined for type Application.

When I try to export this package as jar file to my ice-application the following exception is thrown:

[jerome_082006]

Hi Andreas,

I didn't get that exception. Did you manage to build Icefaces ?

Maybe you should ask someone at Icefaces.

Regards,
Jerome.

[fhh]

Hello!

This is a bug in icefaces and I have a fix for it at home.

Sadly the icefaces people never read the JSF specification. They are using the request parameter map to share objects between different methods.

According to specs the request parameter map is unmutable so you get an UnsupportedOperationException.

I have a fix at home I will post here this evening.

Regards

Felix

P.S.: There are many such careless implementation mistakes. I stopped using Icefaces for that reason. I don't think it is ready for a production environment.

Hello Felix,

thank you for response. Can you please post the fix for this problem.


Thanks

From the ICEfaces forum, the new release of icefaces 1.5.2, which fixes lots of bugs on integration with Seam, will come in next week. We may try the new icefaces release with seam.

Hello!

I'm afraid I have deleted my latest version of icefaces. As I have already written I stopped using it. I do have a patch for the request parameter issue described in the link. I think it is somewhat cleaner:

I just checked in the original sources: The request parameters bug I fixed was somewhere else. The reason it crashed was exactly the same. Ithink in your case it is:

 facesContext.getExternalContext().getRequestParameterMap()
 .put("viewNumber", String.valueOf(viewNumber));

Not sure what this is suppsoed to mean but according to specs you must not put additional values to the RequestParamterMap. If you have fixed this you will find another piece of code where icefaces puts some attribute in to the map to notify another component internally that this is a seam request.

The conclusion I drew from this mess is not to use Icefaces (yet!). I hope this helps you a little.

In fact it is a bug in MyFaces, they are implementing the JSF-specification, so they should make sure that the returned Map is immutable. I filed a bug report some while ago:
https://issues.apache.org/jira/browse/MYFACES-1517

[fhh]

I disagree. The specification only says immutable but does not say what is supposed to happen when somebody _tries_ to modify it.

Throwing an UnsupportedOperationException is in my opinion reasonable. I haven't actually checked what the RI does but silently ignoring the attempt to add a request parameter is surely not an option.

If if the error was swallowed because whatever Icefaces is trying to achieve by putting the viewNumber into the map would ot be achieved.

So this is definitly a bug in Icefaces and this is one more reason why I would not recommend it.

Please read my post and the bug report again. The MyFaces implementation allows the request parameter map to be modified. The RI throws an UnsupportedOperationException (which is good and conform to the specification).
So, this is definitely a bug in MyFaces. You can't blaim the IceFaces people for this.

By the way, ICEFaces 1.5.2 is out and works better with Seam (this issue is fixed, for example).

[kukeltje]

I'll give icefaces 1.5.x a (re-)try in a few weeks. I've been running into so many problems that I've switched back to using Tomahawk (not Gavin's favourite, but a lot less troublesome for me)

What I would certainly advise is to use seam cvs-head (1.1.1) since unexpected conversation endings is fixed there. Which prevents a part of the 'strange' behaviour of icefaces
