Af:tree causes context errors

Question

I'm using an af:tree tag in my page, however I'm seeing many instances of the following in the weblogic log:
<Jul 20, 2011 3:40:22 AM PDT> <Error> <oracle.adf.view.rich.component.fragment.UIXInclude> <ADF_FACES-10015> <Illegal call to setup the context of an include that is already in context>
<Jul 20, 2011 3:40:22 AM PDT> <Error> <oracle.adf.view.rich.component.fragment.UIXInclude> <ADF_FACES-10016> <Illegal call to tear down the context of an include that is not in context>
<Jul 20, 2011 3:40:22 AM PDT> <Error> <oracle.adf.view.rich.component.fragment.UIXInclude> <ADF_FACES-10015> <Illegal call to setup the context of an include that is already in context>
<Jul 20, 2011 3:40:22 AM PDT> <Error> <oracle.adf.view.rich.component.fragment.UIXInclude> <ADF_FACES-10016> <Illegal call to tear down the context of an include that is not in context>

When I first load my page the errors/warnings are not shown. But if I select any row in the tree these warnings come in the logs.
This doesn't seem to affect the user experience.
Anyone got any ideas why this is happening?

Thanks for the reply Timo.
The af:tree code is used in Oracle BPM suite. We are currently using JDev 11gR1 (11.1.1.5.0).
The tree has a selection listener , here is the code --
<af:tree rowSelection="single" var="viewNode"
value="#{pageFlowScope.taskView.viewData}" id="viewTree"
disclosedRowKeys="#{pageFlowScope.taskView.viewTreeState}"
selectionListener="#{taskController.refreshView}"
selectedRowKeys="#{pageFlowScope.taskView.viewTreeSelectionState}"
binding="#{taskListComponentBindingBean.viewTree}" clientComponent="true">
<f:facet name="nodeStamp">
<af:panelGroupLayout visible="#{viewNode.visible}">
<af:image source="#{viewNode.icon}" rendered="#{viewNode.icon != null}"
inlineStyle="margin-right:3px; vertical-align:middle; height:14px; width:16px;"
shortDesc="#{viewNode.toolTip}"/>
<af:outputText id="viewText" value="#{viewNode.name}"
shortDesc="#{viewNode.toolTip}"/>
</af:panelGroupLayout>
</f:facet>
</af:tree>
Code for Selection Listener --
public void refreshView(ActionEvent evt) {
String selectedView =
(String)evt.getComponent().getAttributes().get("viewValue");
TaskView taskView = getTaskView();
taskView.setSelectedView(selectedView);
taskView.setSubTasksView(false);
taskView.setSelectedTaskID(null);
taskView.setSelectedParentTask(null);
taskView.setShowTaskListPanel(true);
if (taskView.getSelectedView() != null) {
taskView.getTaskModel().updateTaskListColumns(taskView.getSelectedView());
taskView.refreshTaskList();
getTaskView().updateTaskChartData();
UIComponent filterPanel = TaskView.getTaskListComponentBindingBean() != null ? TaskView.getTaskListComponentBindingBean().getFilterPanel() : null;
if (filterPanel != null) {
WorklistUtil.refreshComponent(filterPanel);
UIComponent taskListPanel = TaskView.getTaskListComponentBindingBean() != null ? TaskView.getTaskListComponentBindingBean().getSubTaskSwitcher() : null;
if (taskListPanel != null) {
WorklistUtil.refreshComponent(taskListPanel);
UIComponent homePageRightPanel = TaskView.getTaskListComponentBindingBean() != null ? TaskView.getTaskListComponentBindingBean().getHomePageRightPanel() : null;
if(homePageRightPanel !=null){
WorklistUtil.refreshComponent(homePageRightPanel);
where - WorklistUtil.refreshComponent(UIComponent component){       
if(component != null)
RequestContext.getCurrentInstance().addPartialTarget(component);
}
