[xwiki-users] import of a XAR and versions

Hi, I have a question regarding the import of a XAR. When we do an import of a XAR (exported with the History), we have noticed that - when the document NOT contains an attachment - the version history of the document is identical to the original (obviously as expected). However, when the document contains an attachment, it look like a new version of the document is created with the comment being identical to the last available comment. We have experimented with file an DB store (since we have multiple servers in use with different setups) but that does not solve this issue. 1 - Is this the expected result? 2 - Is there a way to work around this (in our case) unwanted result? Thanks in advance for looking at this. Br, Peter
