[Moose-dev] issue with the evolution matrix

Hi, I've started working with Moose with a friend and we have used Kumpel to create a model from a SVN repository and we encountered an issue when trying to create the evolution matrix. Can u help us? One of the models we created is from the svn repository svn://svn.jdownloader.org/jdownloader <about:blank> without user or password. The error we r getting when trying to create the evolution matrix is: VM: unix - i686 - linux-gnu - Croquet Closure Cog VM [CoInterpreter VMMaker.oscog-eem.78] Image: Pharo1.3 [Latest update: #13315] UndefinedObject(Object)>>doesNotUnderstand: #versions Receiver: nil Arguments and temporary variables: aMessage: versions exception: MessageNotUnderstood: receiver of "versions" is nil resumeValue: nil Receiver's instance variables: nil KMPProjectHistory(HismoAbstractHistory)>>completeHistoryCollect:ifNotPresent: Receiver: svn://svn.jdownloader.org/jdownloader (10) Arguments and temporary variables: aBlock: [:each | each] anotherBlock: [:eachRefVersion | eachRefVersion] data: an OrderedCollection() Receiver's instance variables: mooseID: 287595 state: a MooseDefaultState versions: an OrderedCollection(1@nil +1090, -0 2@astaldo +6, -8 3@astaldo +457,...etc... referenceHistory: nil parentHistory: svn://svn.jdownloader.org/jdownloader (10) name: 'svn://svn.jdownloader.org/jdownloader' authors: an OrderedCollection(a KMPAuthor #astaldo a KMPAuthor #coalado) rootHistory: D (1) builder: a KMPProjectBuilder [aView nodes: (self completeHistoryCollect: [:each | each] ifNotPresent: [:eachRefVersion | eachRefVersion]) using: (MORectangleShape new withoutBorder; fillColor: [:each | each == each referenceVersion ifTrue: [Color lightGray] ifFalse: [Color white]])] in KMPProjectHistory(HismoAbstractHistory)>>viewSimpleEvolutionMatrixIn: Receiver: svn://svn.jdownloader.org/jdownloader (10) Arguments and temporary variables: aView: a MOViewRenderer Receiver's instance variables: mooseID: 287595 state: a MooseDefaultState versions: an OrderedCollection(1@nil +1090, -0 2@astaldo +6, -8 3@astaldo +457,...etc... referenceHistory: nil parentHistory: svn://svn.jdownloader.org/jdownloader (10) name: 'svn://svn.jdownloader.org/jdownloader' authors: an OrderedCollection(a KMPAuthor #astaldo a KMPAuthor #coalado) rootHistory: D (1) builder: a KMPProjectBuilder [:each | aZeroArgBlock value] in MOViewRenderer>>node:using:forIt: Receiver: a MOViewRenderer Arguments and temporary variables: aZeroArgBlock: svn://svn.jdownloader.org/jdownloader (10) each: [aView nodes: (self completeHistoryCollect: [:each | each] ifNo...etc...
