Grafoscopio

The current implementation GrafoscopioNode>>#ancestors IMHO contains a logic error. I.e. #level is sent to (parent) instances even if they are nil. The problem is in the way the while loop traverses the parent hierarchy. Fixed code below:

ancestors
	"I return a collection of all the nodes wich are ancestors of the receiver node"

	| currentNode ancestors |
	currentNode := self.
	ancestors := OrderedCollection new.
	[ currentNode parent notNil and: [ currentNode level > 0 ] ]
		whileTrue: [ ancestors add: currentNode parent.
			currentNode := currentNode parent ].
	ancestors := ancestors reversed.
	^ ancestors

Fixed on Grafoscopio-OffrayLuna.248. Please update from Monticello.
