Hi all!
I'm using a folder of fileWrappers as my document format and I've
subclassed NSDocument, NSWindowController and NSDocumentController and
all that.
Everything works fine, except that when a user saves an existing
document after making some changes, it seems that the original
document is actually replaced by a new one. For example, if the
document is on the Desktop or if it has a custom icon, when saving, it
may move around on the Desktop and its icon will be reset to blank.
I though this might have been because it was saving a backup version,
but even if I disable that, the problem persists.
I'm guesing its due to the fact I'm using a directorywrapper of
wrappers for some reson and that it has to re-create all of it every
time, instead of keeping the old one. Do you think this could be the
case?
Before saving the data model of your document, get a recent wrapper to
the appropriate disk location then modify this wrapper to take into
account your data changes, and return the updated version.
This allows to deal with packages containing CVS stuff and so on...
