SCORM 2004 -

[MOLOKO]

After many years experience with SCORM 1.2 this is my first time coming to SCORM 2004 and unsurprisingly have encountered an issue or two!

The first time I run the course, I'm getting a 403 errors when trying to get cmi.suspend_data and cmi.location... is that as expected?

Looking through the (somewhat impenetrable) documentation this does seem to be implied for cmi.suspend_data ("If the SCO has not set the value prior to the get request, then the LMS shall set the error code to 403") but I'm not so sure about cmi.location and why that's returning 403.

Any thoughts? The relevant bit debug output from Moodle is below... Am using the pipwerks SCORM JS BTW.

The logs look fine to me. 

Both cmi.location and cmi.suspend_data get their data from the SCO; if you've never performed a setvalue on those fields, whenever you do a getvalue you will get a 'not initialized' error, which is what you see in the logs. As you said, you see the errors "the first time [you] run the course".

Ah OK cool, thanks for that.

At the moment I have the code set to pop up an error and go into "WTF happened?!" mode whenever any kind of error is received, clearly I will need to tune that down a notch for SCORM 2004... or perhaps amend it so that it doesn't bother get()ing cmi.location or cmi.suspend_data when lesson status is 'not started'.

Are there any other fields that would behave like this?
