hi stworthy,
i met another problem, the DOMs which class="panel window" and class="window-shadow" will not be released automatically when the panel is refreshed.
i use following code as you mentioned:
$('#workspace').panel('refresh','xxx.html');
please give me suggestion. thanks a lot.
Please try to use the 'refresh' method of panel to load external page.
<div id="workspace" class="easyui-panel"> </div>
$('#workspace').panel('refresh','newdatebox.html');
