Ajax dragging not working (fails to 'pick up')

    Details

    • Testing Instructions:
      Hide

      Using Chrome, you will need to open the developer tools, hit F1, and open the 'overrides' section on the left.
      Enable the tools, and then find the 'Emulate touch events' option. You'll be toggling this during testing. Most browsers do not support this.

      Note, with this setting on you'll get a dark circle instead of a cursor.
      Note, you must have the devtools open in order for the setting to take effect.

      You can also test using a device supporting both gesture and mouse interaction, but instead of turning off touch event emulation, you'll have to disable the windows service for touch.

      I would really advise trying this against current stable first so that you can understand what the failure state looks like.

      • Open a course
      • Turn editing on
      • With the 'Emulate touch events' option UNTICKED
      • Refresh the page
        • Confirm that you can move sections, resources, and blocks within the page
      • TICK the 'Emulate touch events' option
      • Refresh the page
        • Confirm that you can move sections, resources, and blocks within the page
      • UNTICK the 'Emulate touch events' option but DO NOT refresh the page
        • Confirm that you can move sections, resources, and blocks within the page

      Note: it is not expected to work if you turn the touch event emulation on after loading the page as gesture detection is only done at page load.

      Description

      in Moodle versions 2.4.x there are numerous reports that Ajax drag and drop isn't working for moving blocks on the course page and the quiz module. This seems to affect latest versions of Firefox, Chrome and IE and occurs in multiple themes.

      When attempting to move sections using the Maltese cross section dragger, Chrome and Firefox will both display a page with the icon image.

      Drag and drop of files does seem to work.

      Clarification:
      This particular bug is about dragging (blocks/activities/sections) failing to 'pick up' the desired object. It will either do a selection, or pickup the move image itself.

            Hi John,

            Any chance you could open your Javascript console and paste the contents of it.
            Also, if you could provide the URL (anonymised if preferred) for the pages you're seeing this, that would also be extremely helpful.

            I'm unable to replicate the issue with moving blocks on the course page - this works for me on 2.4.1 and maste.

            I'm not sure what you mean by moving blocks on the quiz module - could you elaborate further perhaps?

            Cheers,

            Andrew

            Sorry. This is in the firebug console, the head only. Let me know if I should do something else.

            This is on my localhost/xampp install. Its very slow which might be the problem

            I've been trying to replicate this today and haven't so far been successful. The video on the linked discussion makes me think that the Drag and Drop file upload is interfering in some fashion so I've added Davo as a watcher for his thoughts.

            I've so far tried (unsuccessfully) to replicate with:

            • OS X 10.8.2 + Firefox 18.0
            • OS X 10.8.2 + Safari 6.0.2
            • OS X 10.8.2 + Chrome 24.0
            • Windows 7 + Firefox 14.0
            • Windows 7 + Firefox 15.0
            • Windows 7 + Firefox 18.0
            • Windows 7 + Chrome 24.0
            • Windows 7 + IE9

            John: What you pasted above was the page source, not the console output.
            It would be really really helpful to see any output you get from the JavaScript console.
            Alternatively, a screencast/screenshot with the console open would be really helpful and give an idea as to where a problem may lie.

            I wonder whether a piece of javascript loaded between the drag+drop upload, and the toolbox drag+drop is causing some form of breakage.

            I am the person who originally reported this problem on Moodle.org. I am using Windows 7 + FF 18.0 / Chrome 24.0). From the discussions on the original panel it seems there is a good chance this bug is caused by conflicts with drivers used for Smart Notebook hardware/software (http://smarttech.com/software). At home and in school I am using the latest Notebook version for Windows. I don't have access right now to a computer without these drivers, but perhaps the error can be replicated by downloading this software.
