Drag and Drop sample does not work after the editor is destroyed and recreated.

[Piotr Jasiun]

And it looks like a bug in the CKEditor, not a core.

Steps to reproduce

1. ​http://sdk.ckeditor.com/samples/draganddrop.html
2. In the console: CKEDITOR.instances.editor1.destroy();
3. In the console: CKEDITOR.inline( 'editor1', { extraPlugins: 'hcard,sourcedialog,justify' } );
4. Drag any "Contact" to the editor.

Expected result

Drag and drop will work in the normal way, Contact will be inserted.

Actual result

Nothing happen.

In fact, after destroy and recreate, the dragstart event on the contact list is not fired, what is weird, because that event should not be related to the editor instance. What is also interesting I can not attach listener to that event if the editor is not created, because the CKEDITOR.plugins.clipboard is undefined and CKEDITOR.plugins.clipboard.initDragDataTransfer causes error. Also if I add dragstart event on the plugin initialisation it is executed twice.

Other details (browser, OS, CKEditor version, installed plugins)

This was a problem with the code in the SDK.

Whenever the last instance of CKE in the page is destroyed, a reset event is fired which wipes all custom data - among other dragstart listeners.

To fix this the event should be attached whenever an instance of CKE is created.

Moving tickets to the next milestone.

Moving to 4.6.2 minor release, as 4.6.1 is mostly about polishing 4.6.0.

Fixed via ​pull request to the SDK.
