[Xerte-dev] Re: preview.xml not created

Thu Jun 26 12:49:02 BST 2014

Oh, the other weird thing / very worrying thing that happened, after the session ID not set thing, the workspace refreshed to list a whole load of learning objects I have never seen before: I couldn't select any of them, but they are not mine.

This is what I saw:

Should as in will have been... well by design anyway. However Pat or Ron's suggestion of php threading might be something to look into. If the copy is being done asynchronously and returning before it is complete then it could cause such a timing issue. But why now? What has changed?

By the time the id returns, data.xml and media/ should be copied

'Should' as in will have been or 'should' as in might have been?

I'm going to go and have a look later and see if I can figure out what's going on,

I think what Pat is saying confirms that it can only be synchronous.

You click new and give it a name

An ajax call is made to new_template

When it returns with an id then that id is used to instruct the editor which LO to open.

By the time the id returns, data.xml and media/ should be copied. Edit looks to see if there is a preview.xml and if not then it copies data.xml to preview.xml and then loads preview.xml

No, no weird templates, it’s Nottingham for sure.

I’m sure what you say answers my question ‘is it synchronous or not?’ But I don’t know whether it means ‘yes’ or ‘no’.

Subject: [Xerte-dev] Re: preview.xml not created

new template.php ends in a ajax call to the editor, so it's not one block of PHP but one process. New template ends, echoes out a template id, which the ajax gets, and then fires off the editor.

If the editor isn't working, I am suspecting it might be the template is weird? Is it definitely Nottingham? Not one of the old mediainteraction ones or something?

Data.xml is being created, but what seems to fail is the editor opening. Media folder is being created too.

So it's the process of opening the editor that creates preview.xml?

Come to think about it, I had issues myself in the same building on Monday. I just refreshed the workspace and I was in business, didn't really think about it.

I found another user with the same problem: returning to the workspace later, his projects are all there and editable now.

Some sort of timing issue? The editor opening and data.xml hasn't been created yet, so nothing to copy?

Subject: [Xerte-dev] Re: preview.xml not created

Popup blocker doesn't usually stop preview.xml being copied, or at least it's never affected me like that before... plus wouldn't the popup blocker work for others too?

Edit checks for the existence of preview.xml and either opens it or copies the blank

https://github.com/thexerteproject/xerteonlinetoolkits/blob/f5ad19b03ed2c76ac29cbcd0ec5199360dc61d6a/modules/xerte/edit.php#L47

There are a few checks beforehand though that could error out (like below). Check the response in Google Chrome to see if any errors are being sent back i suppose:

    if(empty($row_username)) {

        die("Invalid user id ?");

    }

and

    if(!file_exists($preview) && file_exists($data)){

        copy($data, $preview);

        chmod($preview, 0777);

    }

So it looks like data.xml needs to be there which comes from the Nottingham template. Is data.xml being created in the folder? And a media folder to hold the multimedia?

If not then it looks like this is failing

https://github.com/thexerteproject/xerteonlinetoolkits/blob/f5ad19b03ed2c76ac29cbcd0ec5199360dc61d6a/modules/site/new_template.php#L76

It puts some debug messages into the logs so you might like to check there to see if anything shows up...

No, preview is not created. I think this is maybe to do with popup blocker, so edit never opens.

What order do things happen in when a project is created?

If the user creates a new LO and edit opens then do you see the blank, default preview.xml being copied into in the newly created USER-FILES folder?
