I don't think that this is the root cause of your issue but it may be that
in the
Groovy version you are using "property" is still a keyword.
please try
storeLength('property': 'contentLength')ciao Dierk -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Lars Burgess Sent: Mittwoch, 29.
