Inserting HTML into CKEditor causes NS_ERROR_FAILURE

[eliotsykes]

Using CKEditor 3.6.1 in Firefox 5.0 on Ubuntu, I get this error when I try to drag and drop some HTML into CKEditor (WYSIWYG mode) (I'm using prototypejs to handle the dragging and dropping):

uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMNSHTMLDocument.execCommand]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: http://myhost/ckeditor/ckeditor.js :: q :: line 8765"  data: no]

I also ran this with CKeditor's unminified source and the problem occurs at line 125 of plugins/wysiwygarea/plugin.js:

this.document.$.execCommand( 'inserthtml', false, data );

After the error occurs once, everything works fine. I can drag and drop images and they all work without any errors.

I'm not sure of the exact reason for this error, I couldn't put together a test case to add to this issue unfortunately, however I wanted to report it in case others encounter this error and can provide more details or if they just want to know a workaround.

This error is similar to the error reported here, so that's how the workaround below was found: ​http://dev.ckeditor.com/attachment/ticket/5660/5560.patch

Add this JavaScript to fix the issue

CKEDITOR.on('instanceReady', function(e) {
	var editorInstance = e.editor;

    // Refresh 'contentEditable'
    var body = editorInstance.document.getBody();
    body.setAttribute( 'contentEditable', false );
    body.setAttribute( 'contentEditable', true );
});

The bug also happens with the nightly build (Revision number: 7199) taken on August 15th 2011.

Could you try one more time and provide this TC file?

You may have found a bug in CKEditor that we wish to check but it is impossible without having anything to grab on. What is more prototype is a very popular library which many users are integrating with CKEdititor. That is why we don't like when these two are not getting along with each other.

Waiting for your comments
