[Moose-dev] Bug in Roassal?

Hi! I wrote a new test: --- ROHorizontalLineLayoutTest>>testStretch | previous | ROHorizontalLineLayout new stretch; on: elements. previous := nil. elements do: [ :el | previous notNil ifTrue: [ self assert: el position x > previous position x ]. previous := el ]. --- It is the same like ROHorizontalLineLayoutTest>>testLayout. I added #stretch on the first command. Should it work? It breaks in the message ROHorizontalLineLayout>>doStretchHorizontal:, because it expect aGraph and ask for "aGraph bounds" and others. It obtains a collection of elements. Right now I do not understand what aGraph it should obtain. Thanks for any advise, Jura
