Drag and Drop stopped working

What browser are you using?

I have the same exact problem, using Firefox. I also cannot edit the settings of any pane until I add a new pane, after which I can both edit and move the older panes. Also, when I try to do either the pane turns from blue to red.

Perhaps you have jquery update installed.

See: http://drupal.org/node/194798

Same with me. I did not applied any jquery updates.
I can't add, move, edit the panes. In any browser.

interesting. Once I copied the old jquery.js file from DRUPAL 5.3 to the misc/ directory, everything worked again.

Ok, clearly something I put in the new .js doesn't work right in a newer jquery. Anyone running firebug who could tell me what is failing?

The problem is with this line:

Drupal.Panels.changed($(parent));

in the function Drupal.Panels.attachPane

same issue here. no drag and drop, nor can i edit or remove panes. here is my firebug output

If I remove line 521 ( Drupal.Panels.changed($(parent)); ) of display_editor.js, all errors are gone.
If I remove line 153 of display_editor.js:
item.toggleClass('changed');
the error is gone too, but it seems that the Drupal.Panels.attachPane function is run once with 'html' as parent item!

The side effect is that you won't get the yellow notifications of which panes have been modified; which is probably a fairly minor side effect. If you get this problem, go ahead and comment that line out, for now.

I only have 510 lines in my display_editor.js

The comment line at the top is:

// $Id: display_editor.js,v 1.1.2.24 2007/11/21 21:47:28 merlinofchaos Exp $

And this file came from the alpha14 download.

Did I not get the correct file, or should I comment out line 488 where I found:

Drupal.Panels.changed($(parent));

That is the correct line.

I believe that this is now fixed in CVS, and the -dev version should be generated soon which should contain that fix. It also contains some other stuff, so if you do choose to use the -dev version to work around this bug, be sure to hit update.php.

I tried commenting out Drupal.Panels.changed($(parent));
But to no avail. I still can't edit content or drag and drop. Selecting the content section also removes the sidebars of the page. Also, where can I find the dev version of 2.0? Here's my output anyway (image of display attached):

On http://drupal.org/project/panels click on 'view all releases' and search for -dev. It's pretty easy to find there. Beware that it can be more or less stable depending on what I've been working on that week so be cautious with it. I am a little sloppy with my checkins sometimes.

Thanks for the response.

unfortunately the display issue is not resolved by using the -dev version. Firebug no longer reads the error but now there are no longer any panes showing (image attached) in either Firefox, Explorer or Safari, OS X or Windows.

Really weird info to add! I was messing around and discovered that the mini-panels content interface works - looks and works great by the way! But regardless of whether I go to create a new panel page or use an existing panel page I get what was described above in my last post - nothing to work with.

When you upgraded to the -dev version, did you run update.php? If you have not, can you hit update.php and make sure you don't need database changes?

I'm working with pribeh (hi tom! haha).. I was the one that upgraded to the dev of panels2, I also ran the update.php script after upgrading the module.

merlinofchaos,

Still no luck. I'm even on a separate PC computer (using FF) and get the same display, as I do using two different macs with both FF and Safari, even after running the -dev version and after my partner updated the php script. It also does not display properly under Ubuntu. I'm beginning to suspect something else (a module perhaps) is interfering. What do you think?

Update: I've checked using different themes. No luck.
