[CS5] Unable to save or close a document

Question

I'm working on porting a plugin from CS4 to CS5. One of its functions is to save each page of a document as a separate file. It does this by saving a copy of the main document, opening it, removing the unwanted pages, and finally saving it. This worked fine in all previous InDesign versions, but in CS5 IDocFileHander is returning false for CanSave() and CanClose(). Ignoring that, or processing a save or close command directly, causes ID to enter protective shutdown.
There was another message posted recently with a similar problem  ( http://forums.adobe.com/thread/647045?tstart=0 ), but I'm not performing my actions as part of a command or a command sequence. Is there another reason why InDesign wouldn't allow me to save or close a document?

Hello Andrew,
here is Adam from the thread you already read. I might some more hints for you. First, when I was saving my document, I needed to add a textframe, then export the document *with* the textframe to XML and after that I deleted the textframe so the user doest see anything. So it looked like:
SaveMyDoc(docref)
     1. add a textframe
     2. export my XML file
     3. delete my textframe
     4. call IDocFileHandler to save it <- here CanSaveAs Asserted
When I changed to following style, I got what I needed without the Assert
SaveMyDoc(docref)
     1. call IDocFileHandler to save it
     2. add a textframe
     3. export my XML file
     4. delete the textframe
I got no assert, but the document was dirty and the user had to do Save again which was not nice.
I added line 5:
     call IDocFileHandler to revert to the saved file.
Now it feels OK.
More notes: my methods are in a facade in the model plugin and are called via Utils<IIMyUtils>(). I double checked my commands which set the persistent data in my document.
Lets hope what is written here is useful.
