Question

Moodle + Firefox/Opera + Captivate SCORM = trouble

Forum|Forum|18 years ago

I'm using the Moodle LMS (version 1.8) and created a few SCORM packages with Craptivate 2 to test. When using Firefox (version 2.0.0.4) or Opera (version 9.21) the problems start. Under Firefox I get partial tracking results and the course never gets listed as completed. When using Opera I get absolutely nothing, no scores, not completion, nada, nichts. As soon as I make use of the dreadful Internet Exploder, stuff works like one would expect.

The question of the day, are the Craptivate 2 packages crafted in such a way as that the accompanying .js and .html files are one of these "IE only" deals? It for sure isn't Moodle as it never fails when using IE.

Anyone can shed some light on this?

Thank you jbradley88, I've examinate this post, but in fact I notice that with Firefox the slowness is between Captivate and Javascript (when Captivate call for API using Javascript), and not between the SCORM API and the LMS.

The slow issue is resolved when I force the g_intAPIType to 0 (into the <project>.htm file), so it force Captivate to communicate as if it was into IE.
It seems to work, but I'm wondering if it will have side effects with Firefox.

Here is the code to get CAPTIVATE 4 to play in a Mozilla browser (such as google chrome or firefox)

Captivate creates a file titled: xxxxxcourse.htm

This file contains a bunch a javascript in it:

YOU WILL FIND THIS CODE IN IT....remark it out.

Franck,

Take a look at the post I referenced above. It deals specifically with the slow communication issue.

The issue is not only with Moodle. I reproduce it with other LMS.
I've added logs into the Captivate SCORM dialog. When using Firefox, the Captivate SCORM dialog used is not the same as with IE.
It uses SCORM_support\scorm_support.js and support_support.swf within a Flash local connection.
Each SCORM call seems to be slow (more that 100 milliseconds).

Have you done a search for Moodle in the forums?

Other users have had problems with Moodle and a potential workaround is offered in this thread:

Hello all,

I've got an explanation to this issue with firefox, but no solution.

I've noticed the same problem with a LMS: the final score was not sent, and sco stayed at failed status in my sample.

When I log the dialog with the API scorm and I notice that the calls to SCORM API are slower with Firefox 1.5 and 2.0 than with IE.
So slower, that the Captivate ends, but the LMSSetValue calls was still going during several seconds, with any waiting instruction to the learner.
The learner ends the Captivate before it has time to send all SCORM data to the LMS. As the "completed" status is at the end, it stay at failed status.

Here the log with my sample:
Each call to SCORM API is logged, with the time.
We notice more than 250 milliseconds each LMSSetValue.

At the begining:
16:32:02.884 LMSSetValue : cmi.core.session_time, 00:00:05
At the end, before exiting:
16:32:20.619 LMSSetValue : cmi.core.session_time, 00:00:15
16:32:20 - 16:32:02 = 18 seconds, but in fact only 00:00:15 - 00:00:05 = 10 seconds spent. So => the sending of SCORM data takes 8 seconds late compare to Captivate duration.
If I wait before clicking on Exit:
16:32:26.150 LMSSetValue : cmi.core.session_time, 00:00:29

The complete log:

I downloaded the test suite, created a 2004 SCORM package, and ran the test to the best of my abilities.
It detected several errors:
- The IMS Manifest is not valid against the Controlling Documents
- The IMS Manifest is not valid against the SCORM Application Profile
- The Content Package is Non-Conformant
- he Content Package is CP CAM 1.0 Non-conformant

The test suite available from ADL tests against SCORM 2004 3rd Edition. I do not know if that matters. I also do not know if I ran the test correctly and I have no idea if the reported errors have anything to do with my problem.

What I do know is that no matter if I use SCORM 1.1 or SCORM 2004 format, scoring using IE7 works fine, scoring using Firefox works half the way, and Opera does not work at all.
I can post the scoring log from Moodle if that helps at all, but when accessing the SCORM package with IE all interactions are logged correctly, using Firefox some of the interactions are not reported, and for Opera the list of reported interactions is blank.

I think we can agree that Moodle can be crossed off the list as it does work fine when using IE. Leaves the SCORM package and the browsers. While it seems obvious at first that it is a browser problem, the code run by the browsers comes straight out of Captivate2. That is why I suspect the package to be formed in such a way as that it is "IE only", which just doesn't cut it.

The problem is that I have three players in this game: Moodle, browsers, and Captivate. Of course each will point the finger to someone else.

I guess I will need to find another tool that generates SCORM packages using simulations and test against that. Really something that shouldn't be necessary when using a standard packages.

Hello RamonS_,

Here are the ADL SCOM test suite results as ran from FireFox:

==========================================

I can post the full log if you would like. There was 0 errors or failures on this test.

My personal suggestion would be to download the test suite yourself and run both Captivate and Moodle through this test suite.

Thank you,

Well, I tried three browsers. One works reliably, but is the farthest away from being standards compliant - that is IE. The one in the middle of both is Firefox, and the only fully W3C standards compliant browser available (Opera) doesn't make it work at all.
The LMS is the same, the server is the same, the SCORM package is the same, the only variable that got changed in the client browser which runs the HTML and JavaScript. And those two components are provided by Captivate. So, given this, is there any other reasonable explanation to this?
Firefox 2.x was first released in November 2006, so after Craptivate 2 came out. So that may have something to do with it, but that gave Macrobe half a year to publish an update..

RamonS_,

I don't know - at least, not yet. I think it's a little early to be placing
blame. I know that Captivate 1 files work with Firefox 1.5 (I haven't
tested Captivate 2 with a lot of LMSs using Firefox). When was Firefox 2
released - before or after Captivate 2?

If you contact me off-list - I'll send you a debug file for you to test with
under your environments: Andrew AT LearningConsulting DOT com.

Andrew
