[regression] dojox.layout.ToggleSplitter doesn't update position on double click

[jrasmuss]

After upgrading to Dojo 1.5.0, dojox.layout.ToggleSplitter no longer handles double-clicks properly. It seems to have been broken since May 29th. Double-clicking on a splitter does set the visibility of the relevant ContentPane properly and does update the splitter icon, but the divider location does not change. If a second splitter in the same container is double-clicked, the first moves to the proper location, the second does not. A screenshot is attached.

This problem is consistent across Firefox 3.6.7, IE 8, etc. Changes to BorderContainer.js appear to be to blame: ​http://mail.dojotoolkit.org/pipermail/dojo-checkins/2010-May/075208.html

Hi,

I have the same issue which hindered me to upgrade my application to use dojo 1.5

It should be changed to pass in a width (or height for top/bottom panes) to this.container._layoutChildren, ex:

To close the pane:

this.container._layoutChildren(this.region, 0)

To open the pane:

this.container._layoutChildren(this.region, 300)

However, ToggleSplitter has lots of code in _handleOnChange() and _getStyleProps() for dealing with style, and I don't know what it's for. It seems unnecessary to me, seems like all you should need is that one _layoutChildren() call.

Work on #12689 to change the ToggleSplitter to a 3-state open/collapsed/closed model makes this issue invalid. I think its much improved, but please re-open or file a new ticket if what's in trunk doesn't work for you, or leaves other issues not addressed.
