IE6-8 JS error thrown when pasting with dialog

[j.swiderski]

I have found it when checking #8849 and #9127.

To reproduce:

1. Load the "replacebyclass" sample (important);
2. Select first line and copy/paste it. You should have 7 lines.
3. Select the bold text "sample text" in third line from the bottom;
4. Press Tab key to move focus outside of editor;
5. Click on "Paste" toolbar button; choose to deny clipboard access in order to bring up dialog.
6. Fill in the dialog with some text "abc" then click on Ok

Result: The above TC produces JS error:

Message: Invalid argument.
Line: 938
URI: /ckeditor/_source/plugins/selection/plugin.js

It has been reproducible (IE6-8) from rev. [7239] to [7382]; got fixed in [7383] and showed up again from [7447] to [7517]; got fixed in [7518] and now has been reproducible from CKEditor [7560]

Guys, Please use CRTL+F5 or clear cache from time to time if you have problems with reproducing.

Simplified TC (there is no need to create 7 lines), can be constantly reproduced in IE6:

• load _samples/replacebyclass.html
• select "sample"
• press Tab to focus outside of editor
• click "Paste" button
• "Do you want to allow this page to (..)?" - answer "No"
• type abc in the Paste dialog window
• Result same as above:

   Invalid argument. Line: 938 URI: /ckeditor/_source/plugins/selection/plugin.js

Note: in 3.6.3 I'm getting exactly the same error in the same part of code (the line number is a bit different but it's exactly the same place):

if ( sibling.nodeType == CKEDITOR.NODE_TEXT )
{
	container = sibling;
	distance -= sibling.nodeValue.length; // <----------------
}

To summarize:

• got broken in [7239] (3.6.2) - broken in 3.6.2 stable
• got fixed in [7383] (3.6.3 SVN) and broken again in [7447] (3.6.3 SVN) - broken in 3.6.3 stable
• got fixed in [7518] (3.6.4 SVN) and broken again in [7560] - still broken in 3.6.4

in other words, the issue is reproducible from 3.6.2 when talking about stable releases.

I can reproduce this consistently in IE8 without even tabbing out of the editor:

• Load any sample and type some text.
• Select a word.
• Click the "Paste" button
• "Do you want to allow this page to (..)?" - answer "No"
• Type content in the Paste dialog window and press Ok.

Error:

Message: Invalid argument.

Char: 986

When run with ckeditor_source.js from trunk instead, I get an error when I try to open the paste dialog and cannot complete the testcase. This error is:

Message: Invalid argument.

I cannot reproduce on Windows 7 and IE9 in IE8 browser mode. I have only seen it reproduced on native IE8.

Fixed with [7585].

Replying to garry.yao:

Fixed with [7585].

We still get a JavaScript error after this fix with the following steps:

• Load any sample and type some text.
• Select a word from right to left i.e. start the selection at the end of the word.
• Click the "Paste" button
• "Do you want to allow this page to (..)?" - answer "No"
• Type multiple lines of content in the Paste dialog and press Ok.

Could you please re-open the ticket based on teresa's reply in Comment 12. We could still reproduce the issue that teresa mentioned in comment 12

[j.swiderski]

Fix for this original TC in this ticket is valid but it does not fix the TC presented in comment:12.

TC from comment:12 has been reproducible in IE6-8 the same history as original TC:

• got broken in [7239] (3.6.2) - broken in 3.6.2 stable
• got fixed in [7383] (3.6.3 SVN) and broken again in [7447] (3.6.3 SVN) - broken in 3.6.3 stable
• got fixed in [7518] (3.6.4 SVN) and broken again in [7560] - still broken in 3.6.4

JS error is:
Message: Invalid argument.
Line: 62
URI: /ckeditor/_source/core/dom/text.js

IMO the fix presented in [7585] is incomplete thus I'm reopening this ticket.

I also think that when providing new fix one should check if #9116 and #8978 won't get broken again.

Fixed the second TC mentioned in 12 with [7605].
