Hey Colin,

Interesting bug in Squeak showed up with this, although I suspect it has
been fixed in 3.8.

In OBColumnPanel >> #hopTo: it calls #before:ifAbsent:. This gets called
when you do a find class. In 3.7, #before:ifAbsent: looks like this:

before: target ifAbsent: exceptionBlock
	"Answer the receiver's element immediately before target. Answer
	the result of evaluating the exceptionBlock if target is not an
element
	of the receiver, or if there are no elements before it."

	| index |
	index _ self indexOf: target.
	^ index == 0
		ifTrue: [exceptionBlock value]
		ifFalse: [index == 1 
			ifTrue: [self errorFirstObject: target]
			ifFalse: [self at: index - 1]]

If index = 1, then you get an error rather than evaluating the exception
block, which is clearly not what the comment says it does.

Has this been fixed in 3.8, or am I the only one who ever uses 'find class'
with OB?

Later,
Jon
