I never saw this error. Could you describe exactly what you do?

apparently 

Model1

allNamespace

allclasses

I have the impression that this is when I went from allclasses to Models

I got it several times already and again now.

Now I can reproduce it each time :)

Model1 is selected

allclasses is selected

and you should click in the empty space below Model1

mouseUp: event on: aNodeMorph 

^^^^^^^^^^^^^^^^^^^ nil

| path cmdOrCtrl clickedTheCheckbox |

"No change if model is locked" 

clickedTheCheckbox := self clicked: event inTheCheckboxOf: aNodeMorph.

self listModel okToChange ifFalse: [^self].

self listModel okToDiscardEdits ifFalse: [^ self].

cmdOrCtrl := self commandOrCrontrolKeyPressed: event.

path := (event shiftPressed and: [self isMultiple])

ifTrue: [self shiftSelectMorph: aNodeMorph]

ifFalse: [

self autoMultiSelection

ifTrue: [self selectedMorphList ifEmpty: [] ifNotEmpty: [:l | l last path collect: [:p | p complexContents]]]

ifFalse: [self selectMorph: aNodeMorph multiple: ((cmdOrCtrl and: [self isMultiple]) or: [self autoMultiSelection]) clickedTheCheckBox: clickedTheCheckbox ]].

self selectionUpdateFromViewWhile: [ | selHolder | 

selHolder := self newSelectionHolderWithNodePath: path.

self listModel selection: selHolder].

clickedTheCheckbox ifFalse: [ self lastClickedMorph: aNodeMorph ].

self selectionChanged.

Apparently when I move the moose from the finder elements (classes) to the model item I get
a DNU point:from:
