A user of a SCORM (1.2) course that I developed is having some problems accessing a couple SCOs. By viewing the attempt reports I can see that the lesson_status for both of these SCOs is set to "browsed". There are other elements set (interactions, lesson_location) so they were able to access the SCOs once, but are running into problems re-entering them. My code does not account for a lesson_status of "browsed" so the course is hanging when the status is checked the second time in.
SO ... since the lesson_status appears to be set to "browsed" when the lesson_mode is set to "browse", and lesson_mode has read-only access from the SCO, how does the lesson_mode get set? Is there a setting in moodle that triggers this? Note: the client has no idea how they entered these SCOs in browse mode.
I found it. The teacher had entered two of the activities in Preview mode. This apparently sets lesson_mode to "browse", in turn setting lesson_status to "browsed".
