Sometimes, however, a parcel just needs to *refer* to an item by a
well-known name, even though the item itself is anonymous. For
example, the "me" contact, the "current" account, and so on. In
these cases, a parcel will create a Reference whose ``item``
attribute points to the actual item in the soup, while the
Reference itself lives in the parcel. Reference objects will
therefore be used in place of CurrentPointer objects, and the
inverse relationship of ``item`` will be ``references``. This
means that any personal parcels that now define a ``currentItemOf``
will need to be changed to use ``references`` instead. There will
be a separate posting to announce this change when it happens,
which will give more details.
I have just migrated ContentModel.CurrentPointer to Parcel.Reference,
done away with osaf.current completely, and populated osaf.app with a
few Reference instances, including currentWebDAVAccount and
currentMailAccount.
So the new way to access the "current" WebDAVAccount, for example is to:
app = schema.ns('osaf.view', view)
account = app.currentWebDAVAccount.item
...or to set a new current account would be:
app.currentWebDAVAccount.item = account
I've changed all the code that made use of the old CurrentPointers,
however, if you have a personal parcel.xml which includes accounts
that you want to be default, you need to change your parcel.xml in
the following ways:
Instead of...
xmlns:current="parcel:osaf.current"
...it should now be...
xmlns:app="parcel:osaf.app"
And where you had...
<currentPointerOf itemref="current:MailAccount" />
...that should now be...
<references itemref="app:currentMailAccount" />
I've updated the wiki page with an example personal parcel.xml file:
