Bug 93009 – Range::isPointInRange incorrectly throws WRONG_DOCUMENT_ERR

• Component: DOM
• Status: RESOLVED FIXED

[Emil A Eklund]

The latest working draft of the DOM4 spec has all but killed the WRONG_DOCUMENT_ERR exception. Range::compareBoundaryPoints and Range::comparePoint are the only two remaining uses for it. As such, update isPointInRange to return false instead of throwing an exception when the range and point are in different documents.

This matches the Mozilla behavior.

Nit: this could be:
shouldBeFalse("range.isPointInRange(testNode, 1)")

I don't think that this comment is helpful. A lot of our code is based on research like this, and the best way to figure out the reasons for some code is to change it, and see which tests break.

Such comments are going to get obsolete - we wouldn't be happy if core code was all covered by references to IE 4.

Good idea.

You have a point there, I'll remove the comment.

Thank you.
