soapUI 4.5.1.1 (snapshot) mockservice + ws security + mtom

hi

i am trying to offer a mocked service with soapUI 4.5.1 or 4.5.1.1-SNAPSHOT (Build Date 2012/12/12 00:04) using
- ws security (enc and sig)
- mtom

for testing purposes i create requests also with soapui. when i do not enforce MTOM it works. if i enforce MTOM i get the following error:

Tue Jan 08 12:21:35 CET 2013:ERROR:com.eviware.soapui.impl.wsdl.mock.DispatchException: Missing operation for soapAction [<deleted soap operation>] and body element [{http://www.w3.org/2001/04/xmlenc#}EncryptedData] with SOAP Version [SOAP 1.1]
