&quot;gavin.king(a)jboss.com&quot; wrote : void @Factory methods should not have a scope. The scope is defined on the attribute that does the outjection. Hi, i'm struggling with a similar issue as fernando did: Here some code snippets: DataModel declaration: @DataModel(scope=ScopeType.PAGE) | private Collection<Role> roleDataModel; | Factory declaration: @Factory("roleDataModel") | public void initializeModel() { | log.debug("initializeModel() called (but not used)"); | if (organigramTreeModelSelection != null) | roleDataModel = ((OrganigramNode) organigramTreeModelSelection) | .getRoles(); | else | roleDataModel = new ArrayList(); | | } | xhtml: <rich:dataTable id="roleTableId" value="#{roleDataModel}" | ... | </rich:dataTable> As Gavin wrote the scope has to be defined on the outjecting attribute. Considering @DataModel does only take PAGE or UNSPECIFIED scopes i run into a problem as the datatable (roleTableId) is updated through an ajax request. As follows: <rich:tree switchType="ajax" ajaxSubmitSelection="true" reRender="fwcToolbar, roleTableId" .... | But in this case the PAGE scope i can't use, right? Does anybody have any idea? Help would be very appreciated as i've been fighting with this quite long.. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080599#...
