Problems using rich:tree with seam
Hello all!
I'm new to Seam as well as to Richfaces, but I already love this frameworks. However I'm now stuck with a problem and don't know where to start. Almost all my requests in Google now have all links marked as visited :) Please help!
I want to draw a tree with checkboxes inside a Seam conversation, it might contain different nodes in different conversations (that's why SESSION is not working here). Tree should contain the following structure: Company - User group - Users.
I have followed the code found on http://jboss.com/index.html?module=bb&op=viewtopic&t=122601&postdays=0&postorder=asc&start=10
So I have a page:
<body>
<a4j:form id="treeForm" ajaxSubmit="true">
<h:panelGrid columns="1" id="allPanel">
<rich:panel id="treePanel">
<rich:tree value="#{usersStructure.data}" var="item"
nodeFace="#{item.type}" style="width:300px"
selectedClass="selectedNode">
<rich:treeNode highlightedClass="treeLink"
type="usersCompanyTreeNode">
<h:outputText value="#{item.name}" />
</rich:treeNode>
<rich:treeNode highlightedClass="treeLink" type="userGroupsTreeNode">
<h:outputText value="#{item.name}" />
<h:selectBooleanCheckbox value="#{item.selected}" immediate="true">
<a4j:support event="onclick"
actionListener="#{CalendarEventEditor.processUsersSelection}"
reRender="panelCurrentlySelected" />
</h:selectBooleanCheckbox>
</rich:treeNode>
<rich:treeNode highlightedClass="treeLink" type="usersTreeNode">
<h:outputText value="#{item.name}" />
<h:selectBooleanCheckbox value="#{item.selected}" immediate="true">
<a4j:support event="onclick"
actionListener="#{CalendarEventEditor.processUsersSelection}"
reRender="currentlySelectedList" />
</h:selectBooleanCheckbox>
</rich:treeNode>
</rich:tree>
<h:panelGrid columns="1" id="panelCurrentlySelected">
<h:outputText value="Users, currently participating in this event:" />
<rich:dataList var="user"
value="#{editingOccurence.participantsList}"
id="currentlySelectedList">
<h:outputText value="#{user.name}" />
<h:outputText value="name" />
</rich:dataList>
<h:outputText value="No users selected" id="emptyUsersText" />
<h:messages />
</h:panelGrid>
</rich:panel>
<h:panelGrid columns="2">
<h:commandButton title="OK" value="OK"
action="#{CalendarEventEditor.saveEvent}" />
<h:commandButton title="Close" value="Close" />
</h:panelGrid>
</h:panelGrid>
</a4j:form>
I also have bean for fullfilling its data:
@Name("CalendarEventEditor")
@Stateless
@Scope(ScopeType.CONVERSATION)
public class CalendarEventEditorBean implements CalendarEventEditor {
@Out(required = false)
private UsersStructureTreeNode usersStructure;
...
public void prepareParticipantsList() {
usersStructure = new UsersStructureTreeNode();
...
}
}
prepareParticipantsList is called each time before redirecting to tree page.
Actual result is that tree is rendered but only with a root node, no other nodes are expanded while clicking on a tree. If I change tree switchType to client
, everything works fine until I click on ajax-enabled checkbox (actually, on the second click). Then I receive:

Please help! This is going to make me mad!
