Debugged things a little bit:

org.apache.shale.clay.faces.ClayViewHandler.renderView(ClayViewHandler.java:398)At the viewhandler in line 462 all is fine, a context is there. But when the children are going to be rendered, the call to FacesContext.getCurrentInstance() returns null. Might this be a bug in the jsf implemantation or does shale destroy things which it shouldn't? Any help would be nice - i don't know why the context gets lost, something i should look for in clay or shale which would be nice debug points?
