How to get the Profile-Map of current user within ajax reque

[ameo]

Hello,

I need the Profile-Map of current logged in user. So far I could get the profile Map with:

Object request = FacesContext.getCurrentInstance().getExternalContext().getRequest();
JBossRenderRequest jbossRequest = (JBossRenderRequest) request;
ControllerContext cc = jbossRequest.getControllerContext();
Map userProfile = cc.getUserProfile();

Wthin an ajax request with richfaces like switching tabs I can not get a
handle to the JBossRenderRequest-Objekt. The object is of tye (RequestFacade (?)
Do you know another way how to get the Profile-Map of current user ?

I can not use UserModule!

Greetings,
ameo
