225437 - Insert/HTML <br> does nothing in e.g. an empty document

Status: RESOLVED WORKSFORME

(Core :: DOM: Editor, defect, P5)

Description

[[e-mail]]

Steps to reproduce problem:
1. Open an editor window
2. Use Insert/HTML to insert <br>

Actual results: no effect, although strangely the edit is undoable :-)

Expected results: blank line inserted

This also applies when the cursor is at the end of a block element whose content
does not end with a blank line. If the block's content already ends with a blank
line then a new blank line does get inserted.

Some additional cases that might be relevant:
1. New document
2. Insert/HTML <br>
3. Type X

X gets typed on the first line.

1. New document
2. Insert/HTML <br><br>
3. Type X

X gets typed on the third line, although the cursor was on the second line...

I'm encountering this bug in Firefox 3 Beta 2. I'm doing something like this:
var tempDoc = document.implementation.createDocument("http://www.w3.org/1999/xhtml", "html", null);
var br = tempDoc.createElement('br');

I then create a body element and append a lot of different tags inside that with brs here and there. All is then extracted from this tempDoc and appended to an iframe. Everything looks fine except the <br> tags are apparently ignored. Br tags are not ignored if I append them directly to the iframe instead of creating them in a this temporary document, but I can't always do this.

My current workaround is to use:
var br = tempDoc.importNode(document.createElement("br"), true);

But this assumes you have a "working" document to use.

I'm updating code for Firefox 3. I don't remember this problem in Firefox 1 or 2.

Works as expected.
