Status: VERIFIED WORKSFORME

(Core :: DOM: Core & HTML, defect)

Description

[Scoobidiver (away)]

Build : Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7pre) Gecko/20100926 Firefox/4.0b7pre

This demo fails whatever the change : color, font family, text size, language.

Each time a selection is done, the following error is displayed in the error console :
Error: uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsISelection.getRangeAt]"  nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)"  location: "JS frame :: http://ie.microsoft.com/testdrive/HTML5/60Editor/Default.html :: onclick :: line 1"  data: no]

This demo changed and does not work for me.

Now, the error on Web console is:
Exception: uncaught exception: [Exception... "Index or size is negative or greater than the allowed amount"  code: "1" nsresult: "0x80530001 (NS_ERROR_DOM_INDEX_SIZE_ERR)"  location: "http://ie.microsoft.com/testdrive/HTML5/Editor/ Line: 1"] Source File:  Line: 0, Column: 0 Category: content javascript

WFM. Did you select something before clicking the link?

(The new exception is due to bug 589621.)

> WFM. Did you select something before clicking the link?
Yes. As stated in comment 0, I clicked on any link in that page.

The point is that this is exactly what would happen if no text was highlighted. In that case, window.getSelection() would be empty, and window.getSelection().getRangeAt(0) would throw the exceptions you've seen.

I can't reproduce with 32bit WinXP either; we don't remove the selection when clicking on Win7, do we?

With selected text, it works. Without a selection, there is an error in the Web console. I didn't read well your question in comment 3.
It is the expected behavior.

Okay. (I have to admit that I only realized that I had to highlight something after reading the source, myself.)
