Richfaces components shown although they dont exist in compo

Hi, I guess this is a problem due to mine lack of understanding how is the component tree updated after ajax request. I will try to describe the setting, please help if you know what is going on.

So in a jsp I have a <ui:composition> specified. within this composition there is a form:

<h:form id="startPageForm">
<dnd:panel id="Desktop" binding="#{testBackEnd.deskTop}" style="position: absolute;width:800px;height:800px;float:left;">
<dnd:panel style="width:300px;height:300px;background:black;" >
</dnd:panel>
</dnd:panel>
 </h:form>

After calling a function from rich:commandbutton, I clear the "Desktop" component tree and add some new components within this function programmically. It works fine, BUT the dnd:panel defined in the jsp still stays. I really don't understand why this happens when the component tree is cleared firstly. Funny thing is only rich components stay. If I use jsf standart component it will be properly removed after clearing the "Desktop".children.

Thank you for any help in advance!

PS. <dnd:panel> is a <rich:panel>, I use dnd because there was a conflict when specifying the new namespace

a small progress here, I managed to redraw the panel correctly, now only the existing children in the component tree show.
<a4j:ajaxListener type="org.ajax4jsf.ajax.ForceRender" /> is my solution, ,that has its limitations too. If anyone could explain why this is happening, please do.
