209594 - setAttribute("style", ..) has no effect, if used before addition of element to doc

Status: RESOLVED FIXED

(Core :: XUL, defect)

Description

[Ben Bucksch (:BenB)]

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5a) Gecko/20030608

Reproduction:
1. JS dynamically manipulating the XUL DOM:
   var radiogroup = document.createElement("radiogroup");
   radiogroup.setAttribute("style", "display: -moz-grid-line;
                                     -moz-box-orient: orizontal;");
   document.getElementById("myparent").appendChild(radiogroup);

Actual result:
The style change has no effect

Expected result:
Same, as if the element was directly in the XUL file, including style attribute.

Additional comments:
Thanks to bz, the workaround is to do setAttribute("style", ...) *after*
appendChild(). This works.

This is likely to get magically fixed by bug 209573

Attachment: Testcase

Here is the (somewhat reduced) dialog I was trying to create.

With the bug, you see the radios all below each other. They should be arranged
in a grid, with "bookmarks", "server" and "local" all in one row, "cookies"
etc. in the next row.

I have marked the problematic code.
