Now (2002050904, Win2K) the error is on line 126. And it appears 13 (!) times,
after opening the download manager for the first time in a sesion.

Well, I 'm not seeing this bug in all recent builds (now 2002051908, Win2K).
Fixed with the patch for download manager focus issue?
Marking as wfm. Please reopen if you are still seeing the issue.

mass-verifying WorksForMe bugs.

reopen only if this bug is still a problem with a *recent trunk build*.

I'm seeing this with build 20021004-TRUNK on WinXP-SP1, except the line number
has changed to 159.

Error: gDownloadView.treeBoxObject.selection has no properties
Source File: chrome://communicator/content/downloadmanager/downloadmanager.js
Line: 159

Also, I see that Bug #163884 has a patch that should fix this bug as well.

I have done a fresh install with 2002102508. I am seeing this error whenever I
go to Tools -> Download Manager.

is from the cookie manager (see Bug 176999)

Don't know if this is related, but I'm getting a similar bug in some code I've
been tinkering with:

Error:  this.treeBoxObject.selection has no properties
Source File:  chrome://global/content/bindings/tree.xml#tree.currentIndex(getter)

This is with Mozilla 1.2.1 on Windows 2K.  I believe this occurs during or after
I attempt to set currentIndex for the tree control to -1 to remove the
selection.  Which doesn't seem to work.  I looked at the tree.xml file and I see
how currentIndex is implemented and there is no check to see if the selection
object even exists, so perhaps it is being deleted somehow (or never
initialized) and that causes the error.

Like I said, this may not have anything to do with this particular bug, but I
didn't want to open a new one without checking for an already open one and this
looked suspiciously similar.

(I don't remember to have ever seen this bug, but that's only me.)

Can anyone test this bug (and may be comment 8 too) in a recent build ?

If the bug still exists, can you tell the current line number, even copy some
code lines (if you have installed JS.D. (= Venkman)...) ?

[louis bennett]

this bug looks quite like bug 147842, which was marked as a duplicate of bug 132019.

suggesting -> dupe of 132019.

Comment 11

[Serge Gautherie (:sgautherie)]

Re comment 10:

Bug 147842: you're absolutely right, it was a duplicate of the current one ;-)

Bug 132019: I'm asking there (also), since there have been activity and patch...
