Hello,
We were solving this issue over an e-mail conversation and I'd like to share some hints with other users:
There was problem with workflow which was being used. In this case, it was necessary to use DocumentHelper class to obtain the node object via the
GetDocument method:
node = DocumentHelper.GetDocument(node, tree);
and
UpdateDocument method to save it properly:
DocumentHelper.UpdateDocument(node, tree);
