[Xerte] interesting problem when using SCORM in Moodle

Thu Mar 4 22:41:36 GMT 2010

Works in IE no disappearing and no FF squishing.

So then copied scormRLO.htm to my XOT test file - same old disappearing
problem. 

So out of curiosity copied apiwrapper.js and flash.js from your LO to mine:
Works in IE no disappearing and no FF squishing!

So then copied the .js files one by one to another copy of my LO.
apiwrapper.js no difference. flash.js fixes problem.

So then compared differences between the two .js files

Mine had:

document.writeln('<br>');

document.writeln('<center><div id="sco" style="width:' + rloWidth + 'px;
height:' + rloHeight + 'px;">');

as lines 1 and 2

Yours has:

document.writeln('<div id="sco" style="width:' + rloWidth + 'px; height:' +
rloHeight + 'px;">');

as line 1 replacing 1

replacing line 1 and 2 in mine with 1 from yours seems to fix the problem

Off to test in Moodle!

Confirm for me what happens when you take the zip fie at
http://www.nottingham.ac.uk/~cczjrt/scormTest.zip

Unzip those files into a folder... run the .htm.

It works? Or not? Don't mix any of these files with any of your own. We need
to get to a place where we have one set of working files - I was thinking
maybe you are taking just the .htm and dropping it into your own project - I
need to know these files work or not as they work for me at work, and they
work for me at home.

I could see your flash.js was different to mine, so lets take it a step at a
time,

No idea! I downloaded your zip, extracted it and tried it - vanishes locally
woks fine in FF. Add the doc type woks fine in IE but squishes in FF.

Not going anywhere near moodle with it yet.

It aint the cache and btw the link in your message containing: "Let's wipe
our minds and get on a common set of files." 

To quote "That example doesn't have the doctype at the top of the file."!
;-)

So I added the doc type and it fixes the disappearing problem in IE but
creates the squishing problem in Firefox. 

Adding the docype to your example does the same thing.

Please try the attached not another non XOT LO.

So just to make it 100% clear. The disappearing problem only happens in IE
with LO's set to full screen or fill window. Using the new scormRLO.htm file
with doctype added fixes that problem but introduces a problem of squishing
vertically in Firefox.

That does work in both browsers but...

1.       Something must have changed because your previous version wasn't
displaying full screen.

2.       It would help if we were all using an XOT created LO rather than a
local file because...

3.       Given that this one worked I copied scormRLO.htm pasted in the
folder of the test LO I sent to the list and changed the line pointing to
test.rlo to point to learingobject.rlo result - back to the same problem -
flashes and disappears!

Doesn't work = flashes and disappears!

Deleted everything from Moodle, re-downloaded the scorm RLO, unzipped,
edited scormRLO.htm with the two new body/div tags, saved, re-zipped, added
to moodle using scorm activity or IMS - still briefly appears then breaks.

Here's my modded scorm package - does this work on your Moodle?

Just finished testing and Yes it does seem to fix it for me! However I made
the change locally and then re-imported so as you say there may be some
caching going on in Adam's case.

This is great Julian (and Adam) thanks! - it's cropped up many times but
I've never seen the error Adam reported so never associated it with the
default screen size. A lot of people will be very happy! ;-)

Presumably you will add this to the downloads at some point? 

Also I can find it but to save a few minutes where does the scormRLO.htm sit
in the XOT directory or is it created dynamically? Would be good to be able
to replace a file so that it's fixed on existing installations.

I posted about this issue previously (see subject:  scorm object white
screen) but hadn't discovered that it was the default size option that was
causing the problem. Thanks Adam! At least knowing that's the conflict
provides a short term solution e.g. set size to default. This has actually
cropped up many times but has seemed intermittent - it now seems clear that
the difference is the default size setting.

I've just tested the same LO I was using previously to test the problem and
as soon as that's set to default rather than full screen or full window the
LO works when imported as a scorm. However as Adam says when imported as a
normal zip the fill window works too. It seems likely that there's some
incompatibility between the Moodle scorm code and the full screen fill
window code.

You're right Julian - given that the only interaction tracked at the moment
is the Quiz page type there's few advantages and many disadvantage exporting
and importing as scorm. I usually recommend that people either link to and
use the moodle quiz for quizzes or separate LO's so that only LO's using the
quiz page are exported and imported and the others are just linked or
embedded.

It would be good to identify where the code conflict lies and fix it at some
point because dynamic sizing is definitely desirable but I simply don't have
time to explore that at the moment.

The problem needs looking into. I think it is something to do with the
styles in the html. Compare the code in scormRLO.htm to the code in a normal
index.htm -that might help track it down.

But why export it anyway? Why not just link to the resource from moodle?
That way you can easily edit and update the resource from toolkits, copy it,
give it, duplicate it and adapt it - and all that good stuff.

Hi all

Been experimenting with Moodle using some Xerte RLOs and uncovered a
problem. Exporting a XOT RLO as scorm and importing into Moodle using the
'add an IMS package' works fine and runs as should. However, setting the
'default size' in XOT for the RLO to either Full Screen or Fill Screen
breaks the RLO in Moodle - it completely disappears and leaves the following
error :

Webpage error details

 If I export the RLO as a zip package and then link to the index.htm page it
displays fine from Moodle with the screen default size set.

Any ideas why this might be? I'd prefer it if we could use the full screen
option so that the RLO resizes to match the users browser window - and still
import as scorm (most our students will use laptops which chop off the
bottom of the default sized RLO)
