I'm guessing based on your email that the paragraph starting with:
[EMAIL PROTECTED] (value: <?xml
version="1.0"
Is the output of the debugger when you are running the activity. Is
that right?
If so, then the problem is not that the rim or sock is null. The issue
is that the podUUIDs being saved into the navigation_log are null.
So based on the code you sent the problem is: getItemUUID(item) returns
null.
This is probably because the Pas beans are not actually in Pods when
running in PasOTrunk.
The learner data system gets around this by using a method on the Rim
object called "getContainerId". And in PasOTrunk a extension of Rim
(OTrunkRim) is used so the getContainerId returns the id of the Pas
bean's associated OTObject.
I think the getItemUUID method can be modified, so it determines if the
"item" is inside of a Pod and in that case it uses the id of the pod.
If not then it uses the controllerService to find the OTObject for the
"item", and uses the UUID of that.
Otherwise, we could create fake Pod objects so the PasOTrunk beans are
actually inside of Pods.
This same probably will affect the curnit map code. So before fixing
the navigation log, you should look at the curnit maps code's version of
the getItemUUID method.
So it seems there are 3 places where the UUID of a Pod is used in the
Sail/Pod code:
- learner data system to find the container of the rim
- navigation log to log the id of the current object being viewed
- curnitmap to write out a summary of the activity including id's so
they can be matched up with the learner data and the navigation log.
