In 30456, I'm in the process of porting the Tiling Window Manager. I'm
experiencing this confusing error...
TWMDockingBarMorph DNU @
In DockingBarMorph>>updatePosition there is the following code:
self isAdheringToLeft
ifTrue: [| usedHeight usedWidth |
usedHeight := self usedHeightByPredominantDockingBarsOfChastes:
#(#top ).
usedWidth := self usedWidthByPredominantDockingBarsOfChastes:
#(#left ).
(usedHeight isNumber not or: [usedWidth isNumber]) ifFalse: [
Halt once ].
usedHeight := 1000.
usedWidth := 100.
self topLeft: self owner topLeft - margin + (usedWidth @
usedHeight)].
Pharo is saying that usedWidth = aTWMDockingBarMorph, even though it's set
to a number (for debugging) in the preceding statement. Any ideas?
Thanks.

Cheers,
Sean
