43262 - SUPER-Minimal XUL Tree does not display

Status: VERIFIED WORKSFORME

(Core :: XUL, defect, P5)

Description

[Eric Murphy]

I have run across two seemingly incredible bugs. This one, and 40612. It blows 
my mind, and also is giving me an incredible time trying to develop anything.

I have attached a super minimal tree. Now, the file displays in builds circa-
M13. It no longer works.

This is affecting more complex XUL files too. For example, I am working on a 
Jabber client for Mozilla, and all my old stuff does not work anymore. This is 
a real problem because the rest of it requires a new build to work.

So, I personally would consider this, and 40612 blockers.

Also, in M16, if I go to the debug menu, and try the tree example, it will not 
load.

Triaging Clayton's buglist: Yup, that xul file doesn't display a tree.

Unfortunately I have to plead ignorance here too, and pass the baton on to the 
XUL guys.  If you can find the time, please just paste in a minimal example of a 
tree, thanks!

A new implementation for <tree>s landed jun19, and with it come some 
different requirements for syntax. Sorry for the inconvenience, but I
myself am just beginning to grok the new way. 

If you set <treechildren flex="1">, then the contents of the treeitem 
will be displayed. You should also ensure that you have a <treecol> for 
each column (declared in a <treecolgroup> (a.k.a <treecols>) elements. 

See news://news.mozilla.org/3946BCD6.ED374094%40netscape.com for more. 

Since setting 'flex="1"' displays the simple tree contents to me, marking
WORKSFORME, but please file bugs for other anomalies you encounter. Thanks.

... however, I was talking with hyatt and he asked me to file a bug to make
the default attribute for treechildren and treecol be flex="1" if not otherwise 
set by the author -- bug 43680. (and also that the default height and width of 
a tree be reduced, which he is considering -- bug 43681).
