Subject Re: I: problem with getting contentstream of object
Date Sat, 06 Sep 2014 08:10:13 GMT
Hi Erwin,

Which repository are you connected to and which CMIS binding are you using?


You get a "Property 'gu:letterCharacteristic' doesn't exist!" error
message if either the repository returns incorrect type definitions or
if you try to connect to a CMIS 1.1 endpoint. (DotCMIS does not support
CMIS 1.1, yet).

Can you download this document with the CMIS Workbench?
