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
