Subject: [squeak-dev] bug in OBMetagraphBuilder>>#reference
To: squeak dev <squeak-dev@lists.squeakfoundation.org>

Hi, I just wanted to let the maintainers of OmniBrowser know, there is
a bug with this method.

The method reflects on its class and performs all that begin with
#populate. �However, it is not unusual to expect that someone's
application might have a selector that also begins with the word
'populate'. �And so those selectors would be performed as well.

This is why, for cases like this, it is better for a tool, which is
just a means, not an end, to be polite with the namespace; such as
checking for 'obPopulate' perhaps rather than simply 'populate'.

But that's just a mini-rant, not even the bug. �The bug is, my
'populate' is not a unary message, so I get a failure on the perform,
"incorrect number of arguments."

I therefore always change the method to:

OBMetagraphBuilder >> execute
� � � �((self class allSelectors select: [:ea | (ea beginsWith: 'populate')
and: [ ea isUnary ]]) asSortedArray)
� � � � � � � �do: [:selector | self perform: selector].
� � � �^ self root

Thank you,
�Chris
