Reset tinyMCE content without re-render the editor

[zjda]

Hi. When a tree node is selected, the rich:editor will display its content. However, using reRender attribute will make the tinyMCE refresh every time a tree node is clicked, which is not efficient and looks ugly. In an EXT JS-struts project, I can update the editor content:

Ext.Ajax.request({
 url: "<%=contextPath%>/item.action",
 params: {dispatch:'getContent', sectionId:newSelectedNode.id, splId:root.id},
 success: function(r)
 {
 document.itemForm.content.value = r.responseText;
 }
});

Could someone give me some sample code to do it with Richfaces by using JavaScript to update tinyMCE content from backbean without refreshing the editor?

Thanks,
