Not sure if this is the final solution, but error is avoided by adding  
asOrderedCollection...
GLMTreeMorphModel >> roots: anObjectOrCollection
        roots := anObjectOrCollection isCollection
                ifTrue: [ anObjectOrCollection ">>"asOrderedCollection"<<" collect:  
[:each | self nodeModelFor: each ] ]
                ifFalse: [ OrderedCollection with: (self nodeModelFor:  
anObjectOrCollection) ]

------------------
Otherwise...
* anObjectOrCollection is a FreeTypeCacheLinkedList, whose #collect: &  
#addLast: methods require elements to understand #nextLink and #previousLink
* block-variable :each is a FreeTypeCacheEntry, which does understand these
* the result of [self nodeModelFor: each] is GLMTreeMorphNodeModel, which  
does not

Thanks. Fixed. Although it is probably less efficient when we have other  
types of collections, it should be fine for now.
