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

I don't know for sure (Pat or Tom might though offhand) but I can try to trace the route later tonight. I wouldn't expect them to be asynchronous though...

So when it happens, if you refresh the editor then does the editor opens successfully with the blank LO? Do you see a 404 error in the network traffic for the editor at first when it happens?

Are all the file creation / copying methods synchronous?

Could it be that data.xml hasn't been copied when the editor tries to open  -and then in turn duplicate it into preview.xml?

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?

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?

We have only one of these usernames, dating from 2006, so predates toolkits, and not a duplicate.

No, that looks right. At least the folder has the correct user name in it.

I'll check that. I didn't notice anything obvious though...

My hunch would be a username issue - check username matches the folders being created including case sensitivity?
