I have a pretty basic storyline eLearning module with a graded quiz at the end. It is published for TinCan, and course completion is based on a graded result slide and is hosted on SCORMCloud. It works fine on PC, and gets through the content on the Mobile player. But when I complete the quiz and get to the results slide I get a Connect to server error, which I cannot get out of through retry, only close. Completion and the interaction results are not recorded from the mobile player. Anybody have any success with this situation? If so any suggestions?
I am hoping you can help direct me to a clearer answer to how to remedy my problem. I am working with both SCORM Cloud support and with VIra (Case #00318111) to sort this out. Although SCORM Cloud supports launching the Articulate Mobile Player, it does not seem to be able to register course completion or track results. At least some user data appears to be saving, since I am prompted to resume the course from Scorm Cloud started on the Mobile Player on my PC and can complete the course there.
So I have questions for QA or development - are there any edits I need to make to the tincan.xml file to make it work with SCORM Cloud? Of course, I am working on a project that is expected to launch in a few weeks, and gradually roll out to iPads. I don't think the client will accept that they cannot use the iPad to complete the course. And frankly, Storyline HTML5 output on Mobile Safari is still not ready for primetime as far as I can tell.
I am appealing to you so that I can at least get an understanding as to whether the use of the mobile player with SCORM Cloud (or any LMS other than Articulate Online) is something that is on the radar and can be addressed?
Thanks so much. I understand that there must be thousands of important issues and I appreciate Articulate's customer centered approach and the ability to get answers, if not solutions!
I hope you are not too badly affected by the incoming blizzard (I'm in NYC, where it is expected to hit but not as bad as elsewhere.
Sure thing, Paul. We really appreciate you taking the time to help us not only find the issues, but also taking the time to work with us to get them resolved.
Be safe in the blizzard. I was living in NYC for the 2010 Christmas blizzard and loved it!
Just heard back from Vira RE: Case #00318111. Support is able to duplicate the error, but there is no time frame for if/when this may be addressed. Is there any way to get any more detailed information?
Our senior engineers have logged the issue with the QA team. As soon as QA receives it, they will attempt to resolve it as quickly as possible, including offering workarounds, if possible, and then they will update us. Not much left for me to do on my end, but I will follow along and update the thread with any information I receive.
Really sorry for the inconvenience and frustration.
The given tincan.xml was incompatible with latest version of the Tin Can API specification. Error was: Activity ID '6jQaW8AslU5_course_id' is not an absolute URI
My understanding is that the Activity ID error is not the cause of the problem, in that course completion is achieved using a browser. Also there was at least one instance where we were able to complete using the player, but not since Feb. 5.
I've discovered the error and attempted to bring it to the attention of Articulate Support. But, to no avail, they've simply referred it to Rustici.
In a previous exchange with Articulate Support, I brought their attention to the fact that when the Mobile Player submits a statement with results, it adds the 'extensions' attribute to the 'object'. This does not occur in the Flash container communications. So, I took it upon myself to submit an identically formatted statement to the Public LRS at Rustici in order to receive a more complete feedback. With the Mobile Player, no feedback is given regarding the error.
Below is the error returned from the Public LRS when sending the Mobile Player statement using their online statement generator.
Notice that the error reflects that the field 'extensions' is not recognized. This only occurs with the Mobile Player since only the Mobile Player sends this field. As a side note, I also reported that the result score is incorrect when sent from the Mobile Player.
Error returned from Tin Can/Rustici Public LRS:
There was a problem communicating with the Learning Record Store. (400 | statement could not be created from given JSON. Error message: Unrecognized field "extensions" (Class RusticiSoftware.ScormContentPlayer.Logic.TinCan.TinCanActivity), not marked as ignorable

Unfortunately, we do not have documentations regarding the questions you raised. Customization or building of LMSs/LRSs falls outside the scope of our support. Our Tin Can API documentation (http://www.articulate.com/tincanapi) is just provided as a courtesy. Any further help or info will need to be sought from Rustici.
One more side note regarding the use of 'extensions' in the 'object' of a statement. According to the .95 API specs, the 'extensions' attribute must be added to the 'definition' key of the 'object'. When added by the Mobile Player, it is added directly to the 'object' as opposed to the 'definition' of the 'object'. See below and note how an actual statement captured from the Mobile Player adds the 'extensions' attribute to the 'object'. This is rejected by the SCORM Cloud and the Public LRS.
Thanks for sharing your experience and analysis of the problem. I am still very eagerly awaiting a response from Articulate Senior engineers as per Peter Anderson's post above.

I've asked Rustici support to provide sample code for adding the extension to the object definition. Note that the error messge states that "the extension key tracked is not a valid URI", and Rustici support says "Extensions must be in the object definition and the key must be a URI." Perhaps with the correct formatting of the tincan.xml file, SCORM Cloud will accept the statement as written by the mobile player.

Would you be able to send us the file so we can work with it? Thanks!

Thanks, Paul. Wanted to let you know that I've escalated your case to our senior engineers. You should be hearing from one of them shortly.

Peter,
Thanks for your assistance, and I really hope they can fix the issue before my project is scheduled to roll out!

I'm having the same issue... Also I don't have the option to download the course for viewing offline.
I am curious if this is a recent development or otherwise?
This appears to be a new issue. We're looking into it and will be posting updates as they relate.
Thanks again for your patience
I had also submitted it as a case with ScormCloud support - if it is helpful for your team the ticket number is 11524.
Could it be that currently, Storylinecontent is 0.9 spec compliant and some LMS's may have support only higher versions of TinCan?
I did get this when I uploaded to SC

Subject: Re: Case #00318677: Is there a white paper or some thorough ... [ ref:_00D30Txo._50040P0lEZ:ref ]
At this point my main concerns are specific to the Articulate Storyline
reporting with regards to the following:
1. Inconsistencies in reporting when using Articulate Mobile player and
the Flash player.
2. Use of the 'extensions' attribute within an Articulate reported
statement. (I've only observed this in the Mobile player.) There is no
documentation of how data is reported within the 'extension' attribute and
is entirely specific to the content per Rustici documentations. So, this
is an Articulate functionality that I'd like to know more about so I can
more accurately report on the data. A specific example is
'"extensions":{"tracked":"true","master":"true"}' which was included in a
statement generated for a Result object that is used to report overall
course completion.
Thanks again.
Jamie Smith
[/collapse]One more side note regarding the use of 'extensions' in the 'object' of a statement. According to the .95 API specs, the 'extensions' attribute must be added to the 'definition' key of the 'object'. When added by the Mobile Player, it is added directly to the 'object' as opposed to the 'definition' of the 'object'. See below and note how an actual statement captured from the Mobile Player adds the 'extensions' attribute to the 'object'. This is rejected by the SCORM Cloud and the Public LRS.

Also, I did try relocating the 'extensions' attribute to the 'definition' of the 'object'. The Public LRS returned the following error.

Jamie,
Thanks for sharing your experience and analysis of the problem. I am still very eagerly awaiting a response from Articulate Senior engineers as per Peter Anderson's post above.

Ditto. I really need to get it to work soon.
Thanks, guys. I've updated the ticket to include Jamie's findings. Will continue monitoring and asking for regular updates.
Rustici support (ticket #11524) confirms:

Thanks, Paul. Just added that as well.

I need a solution pretty soon as well...
