276880 - [FIXr]accessing textContent property of dynamically created node not yet inserted into the document causes NS_ERROR_FAILURE error

Status: VERIFIED FIXED

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

Description

[Martin Honnen]

The W3C DOM Level 3 Core specification in
<http://www.w3.org/TR/2004/REC-DOM-Level-3-Core-20040407/core.html#Node3-textContent>
defines a property textContent for nodes and according to
https://bugzilla.mozilla.org/show_bug.cgi?id=210451 Christopher A. Aillon
implemented that property in Mozilla.
However when I try to access that property on a dynamically created node (in the
test case an element node) that has not yet been inserted into the document then
Mozilla throws an error:

Error: [Exception... "Component returned failure code: 0x80004005
(NS_ERROR_FAILURE) [nsIDOM3Node.textContent]"  nsresult: "0x80004005
(NS_ERROR_FAILURE)"  location: "JS frame ::
http://localhost/javascript/test2005010302.html :: testReading :: line 12" 
data: no]
Source File: http://localhost/javascript/test2005010302.html
Line: 12

That happens with both Mozilla 1.7.5 (the latest release at the time of this bug
report) as well as with the current nightly (which is Mozilla 1.8a6
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a6) Gecko/20050102).

I do not see anything in the DOM specification that suggests that accessing the
property on a node not inserted into the document should cause an error
therefore I file this bug.

I am going to attach the test case next.

Attachment: test case (accesses textContent property of element node created by static HTML which works, then tries to access textContent property of dynamically created node, see js console for error

Maybe nsNode3Tearoff::GetTextContent should use GetOwnerDocument instead of
GetDocument?

Verified that test case https://bugzilla.mozilla.org/attachment.cgi?id=170158
now works with
Mozilla 1.8a6 (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a6)
Gecko/20050105).
