[Xerte-dev] Re: 2 odd issues user-files contents and export - Tom?

Yep that's fixed it - great!

Did something change in 1.8 to break this? As far as I'm aware that Google
Map page hasn't changed from the Notts 560 example which exports fine from
what I assume is a 1.7 install.

Either way if people upgrade to 1.8 and then find they have some
existing/older LO's which don't export when others do what do they look for?

Presumably this is a change to the wizard that you are going to commit?

Cheers

Ah, ok.

This wizrd fixes it partly. You NEED to change the offending line (but you
don't know which one...) In this case, it is only one. the url of the google
maps page.

Please can you try the following to confirm:
 - Open page with the new wizard
 - Add a space after the url
 - remove the space again (thes two actions will trigger the code changes)
- Save, and try to export.

Thanks!

Hi Tom

assuming you mean /modules/xerte/engine/wizard.swf

I replaced that, edited the LO, tried deployment and archive exports and
same problem as before - blank window.

Turned on developer mode temporarily and have attached the errors as well as
data.xml

Possibly worth pointing out that this project started as an export of the
Notts page 560 LO so began life many years ago!

Ron,

Can you please try this wizard.swf? You should load the LO in the wizrds and
save it first, because the work is done in the wizard.

If it is NOT working, could you please send me the data.xml?

Yes, it is a simplexml load error. It can't handle the '&' signs in the
urls. I am busy fixing this in the wizard, but it's not ready yet.

Thanks Tom

I've sent you the long list of errors offlist - seems like it might be a
simplexml_load issue?

Yes, export will copy data.xml to template.xml and after finishing with the
export, the file should be deleted.

This indicates that php crashes somewhere during export.

I'll see if I can see something in the code. A while back I added some
_debug statements to export.php, can you afford to switch on developer mode
in config.php? There should be a debug.log file in folder /tmp that might
give us a clue of what is going on. But be carefull, full php error
reporting will be switched on. Don't do it in a production installation!

Just a quick update - it's upon attempting to export that template.xml is
getting written back to the user-files folder for this project - any ideas
how/why?

Thanks for the responses Julian/Tom

1. Not sure why this has happened in a few places but not a major problem if
it's not happening all the time.

2. a. nothing relevant in the error logs so I guess it's not escaping
causing the problem

b. Full archive doesn't work for this project either - just a blank window
when trying to export this particular project

Curiously despite deleting it template.xml keeps getting written back to the
project folder in use-files so there's data.xml, preview.xml and
template.xml can't see why or where that is happening but wonder if it's
linked to the problem?

Cheers

1. The only instance where I expect models etc in the user-files, is when
importing a learning object that does not have a corresponding template  in
the installation.

2. You can verify whther escaping is the culprit in two ways
a. You should see a fatal php error from SimpleXML.load in the log files
b. Full archive export should work (as it doesn't try to read the data.xml)

Hi all

this might be a question for Tom unless others have see either of these
issues too....

1. I've notice that some projects in the user-files folder get populated
with folders and files that shouldn't be there e.g. common, languages,
models etc. I haven't been able to identify exactly what causes this. Anyone
seen this and/or got any idea re cause/solution?

2. The example of the page 560 LO we've shared and developed on the 1.8 test
install won't export - I just get a blank window when clicking export but
other LO's do export. So I've been testing this with a copy and if I replace
data.xml and preview.xml with xml from a simple LO the project exports. I'm
wondering if there's a particular page type causing the problem or if this
is related to the Issue Tom mentioned about html escaping e.g. there are
lots of < in the xml.

Cheers

Ron
