[opencms-dev] setContents() and writeFile() not enough to save?

[jill]

I'm currently writing a WebDAV hook into OpenCms, and I'm stumped on one last
major function.

Jakarta's SLIDE project has a setResourceContent() method that is called
when you attempt to save a file.  I have verified that my method is grabbing
the right file with the newly-altered content and that I'm attempting to
store to the correct project (Offline).

After getting my byte array with the edited content in it, I call CmsFile's
setContents() function and then call CmsObject's writeFile() function.  

An oversimplified glance at what I'm doing, with CmsObject obj and byte[]
content:
CmsFile file = new CmsFile(obj.readFile(resourceUri));
file.setContents(content);
obj.writeFile(file);

It does save my changes through WebDAV because I can close the file and
reopen it through WebDAV and see the changes I saved.  However, when I look
at the file in OpenCms, it hasn't picked up any of the changes.  What's
more, after looking at it in OpenCms, it reverts the file that's served
through my WebDAV server (which is probably a good sign--at least I'm
pulling the file directly from the database instead of caching it somewhere
on my machine).

I'm able to edit and save in OpenCms and see the changes reflected through
my WebDAV client, but not vice versa.  I've stepped through
CmsSimpleEditor's actionSave() method and can't figure out what my code is
doing differently.  Is there something I need to do to broadcast to OpenCms
that I've changed the file?  What purpose does the setAction(ACTION_SAVE)
call at the end of the actionSave() method serve?

I've tried restarting Tomcat immediately after saving through WebDAV to see
if it would pick up the change through a total refresh, but no luck. 
Somehow the changes are not sticking in the database (or even getting into
the database?).  I'm missing an important call to OpenCms somewhere and I'm
just not seeing what it is.

Any suggestions would be appreciated.

Thanks,
Jill
