DHTMLXTree and partial page refresh with AJAX

Hi,

I’m using the free version of DhtmlXTree and Java (struts 1.1).
In my program, I’m using AJAX to refresh some parts of the web page and some are containing a DX Tree.
Under IE6 and Firefox, this works perfectly, but under IE7, the tree don’t show up without returning any javascript error.
That’s hard to make a working example without the entire (big) project files,but the simplest jsp containing a tree is as following:

[code]<%@ page contentType=“text/html;charset=UTF-8”%>
<%@ taglib uri=“http://jakarta.apache.org/struts/tags-logic” prefix=“logic”%>
<%@ taglib uri=“http://jakarta.apache.org/struts/tags-html” prefix=“html” %>
<%@ taglib uri=“http://jakarta.apache.org/struts/tags-bean” prefix=“bean” %>
<%@ taglib uri=“http://jakarta.apache.org/struts/tags-tiles” prefix=“tiles” %>
<html:form onsubmit=“return false;” action=“/tree” name=“TreeForm” type=“fr.myorg.myapp.view.common.tree.TreeForm” scope=“session”>

[/code]

The page is called via an ajax call to a struts action ( tree.do)

The block output is as following (firefox - view generated source code)

[code]

Make sure that tree container has desired style (the container is visible in IE7)
