Whilst creating some SCORM 1.2 objects in CourseLab and importing them into Moodle (1.9.9+ and 2.0) I keep getting an alert message when moving between slides:

ScormApi2004.LMSCommit:
General exception

Investigating the call to "mod/scorm/datamodel.php" results in "true\n0" however I found the following lines of code:

scorm_12.js
433: result = ('true' == result) ? 'true' : 'false';
434: errorCode = (result ==' true')? '0' : '101';

which results in errorCode always being set to '101' (general exception), causing the alert message. (note proceeding the space in ' true').
