Florian, Can you please create a new issue at http://jira.codehaus.org/browse/CASTOR, and attach all relevant files (self-contained and minimal XML schema, binding file (if used), builder properties (if used) and XML document instance used to produce the error). Once evertyhing has been uploaded, we'll be having a look.
And pretty please always make it clear what version of Castor/Java you are using, as this might be relevant.
