[seam-issues] [JBoss JIRA] Commented: (JBSEAM-4652) Using JSF 2 And Seam

[Marek Novotny (JIRA)]

    [ https://jira.jboss.org/browse/JBSEAM-4652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12565547#comment-12565547 ] 

Marek Novotny commented on JBSEAM-4652:
---------------------------------------

1. I didn't attach the SeamViewHandler to the issue, varun shaji did that ;-).
2. although you can remove Override annotations from added methods, you still will miss some new classes from JSF2 API, which are used in declaration of these added methods and of course you can't delegate calls to javax.faces.application.ViewHandler in these method implementations if you don't use reflections for invoking of these missing methods.
3. Anyway if you do it, then there is still issue with facelets in JSF2, which have different packages and as we know from JBSEAM-4637 also different declared constructor.

So if we want to support FULL JSF2 mode in Seam 2 not only JSF 1.2 compatible mode under JSF2 runtime, there should be done some work on jboss-seam-ui.jar, jboss-seam-debug.jar and also some code change/review for jboss-seam.jar, where is JSF integration in org.jboss.seam.jsf package.

> The same example works fine with JSF 1.2.But with JSF 2.0 i get the same exception for Seam 2.2.0 and 2.2.1
> Anyhow i get the seam variables resolved and application succeefuly deployed with JSF 2.0 but this error during page transition occurs. I use pageflow (jbpm-jpdl.jar) for stateful navigation.
> Any clues??
> My pageflow file reads like::
