I do not know whether xhtml is relevant in this case. I have digged one step further - Eaten Exception occurs during Outjection of a datamodel:

  | @DataModel
  | public Collection<Akteur> getEigentuemer() {
  |   Attributlieferant al = getAttribute();
  |   if (al == null) {
  |     return null;
  |   }
  |   return al.getEigentuemer();
  | }

Exception occured in "getAttribute" call, but method getEigentuemer should only be called by seam, not by jsf. xhtml directly accesses the outjected datamodel:

  | <ui:repeat var="p" value="#{eigentuemer}">
  |   <h:outputText value="#{p.anzeigename}" />
  | </ui:repeat>

Ok, admit, I don't know why I used a DataModel for this special case. But keep in mind that I am still learning Seam by doing ...
