Hi there, Try checking the library (the rich faces jars) whether they are all the same version? If not necessary, dont put the rich-faces jars in the server deployment library (/server/default/lib). I had the same problem and managed to fix it that way.

hi lowecg2004,
first of all thank you for your post, i tried all versions of seam and jboss
application server,
is this so difficult that use seam and richfaces together ???
i already tried this for a week but could not resolve :(
environment :
1. JBoss AS 4.2.0GA
2. Seam 2.0.0.BETA1
3. Richfaces 3.0.1
4.ajax4jsf 1.1.1
here is my example simple dynamic tree generation into seam component :
1.MenuBean.java (Seam Component)
| @Name(menu)
| @Scope(ScopeType.SESSION)
| public class MenuBean{
|
| @In
| private EntityManager entityManager;
|
| private HtmlPanelBar bar = new HtmlPanelBar();
| public MenuBean() {
| }
|
| public HtmlPanelBar getBar() {
| if (bar!=null bar.getChildren()!=null) {
| bar.getChildren().clear();
| }
|
| ArrayListMenu arraylist =
(ArrayListMenu)entityManager.createNamedQuery(Menu.findAll).getResultList();
| for (Menu elem : arraylist) {
| HtmlPanelBarItem item= new HtmlPanelBarItem();
| item.setLabel(Bl);
|
| Library library = new Library();
| HtmlTree tree = new HtmlTree();
| tree.setStyle(width:150px);
| tree.setValue(library.getData());
| tree.setVar(item);
| tree.setNodeFace(library.getType());
|
|
| IteratorArtist itArtists =
library.getArtists().values().iterator();
| while (itArtists.hasNext()) {
| Artist artist = (Artist)itArtists.next();
|
| HtmlTreeNode artistNode = new HtmlTreeNode();
| artistNode.setType(artist);
| HtmlOutputText artistText = new HtmlOutputText();
| artistText.setValue(artist.getName());
|
| IteratorAlbum itAlbums = artist.getAlbums();
| while (itAlbums.hasNext()) {
| Album album = (Album) itAlbums.next();
|
| HtmlTreeNode albumNode = new HtmlTreeNode();
| albumNode.setType(album);
| HtmlOutputText albumText = new HtmlOutputText();
| albumText.setValue(album.getTitle());
|
| IteratorSong itSongs = album.getSongs();
| while (itSongs.hasNext()) {
| Song song = (Song) itSongs.next();
|
| HtmlTreeNode songNode = new HtmlTreeNode();
| songNode.setType(song);
| HtmlOutputText songText = new HtmlOutputText();
| songText.setValue(song.getTitle());
|
| tree.getChildren().add(songNode);
| }
| tree.getChildren().add(albumNode);
| tree.getChildren().add(artistNode);
| item.getChildren().add(tree);
| bar.getChildren().add(item);
| }
| }
| }
| return bar;
| }
| public void setBar(HtmlPanelBar bar) {
| this.bar = bar;
| }
| }
|

i tried to find something into seam code but i could not find anything for this
issue,
you told me about configurations lowecg200, here is my configurations :
1.components.XML
| ?xml version=1.0
[jboss-user] [JBoss Seam] - Re: Seam, problem with EntityManager
Hello Paata, Your code and persistence.xml/components.xml config look okay to me. Do you have an entry in your startup logs that looks like the following? 16:53:36,554 INFO [Component] Component: entityManager, scope: CONVERSATION, type: JAVA_BEAN, class: org.jboss.seam.persistence.ManagedPersistenceContext If your entityManager was successfully created then you'll have an entry like the one above. Otherwise, you'll not. This will at least tell us if there is a config issue or not. Have you still got the managed-bean config from your original post hanging around? I'm using RichFaces without any problems. As for your EJB3 question - I don't know the answer to this, hopefully someone else can help you here. Maybe you could try making your Seam POJO into a SFSB? As a SFSB you could also try @PersistenceContext for getting at your entityManager? Could you post your web.xml and faces-config.xml? Regards, Chris.

if you have the following in components.xml core:managed-persistence-context name=entityManager | auto-create=true |persistence-unit-jndi-name=java:/TestEntityManagerFactory/ you can use @In(create=true) | private EntityManager entityManager; But one question. Why you have managed-bean stuff in faces-config.xml? This should be handelt from your annotations in your bean, I think!
