Workspace acceptDroppingMorph was missing an assignment

[jpenneygit]

I think I fixed it, the original on my image was missing the assignment (this is approximate, i didn't record the original code exactly):

(dropee isKindOf: TransferMorph)
	ifTrue: [reference := dropee passenger.
		externalName := dropee passenger className]
	ifFalse: [reference := dropee.
      ].

And instead just left externalName as nil, so when you got to "externalName := externalName isOctetString" it reported an unknown object.

I changed it to:
(dropee isKindOf: TransferMorph)
ifTrue: [reference := dropee passenger.
externalName := dropee passenger className]
ifFalse: [reference := dropee.
externalName := dropee externalName].

(just adding the assignment to externalName)

This was a Squeak 5.1 32 bit image, You should be able to just look at the code and it's obviously wrong. If you want to reproduce, open a workspace, open any new morph with openInWorld, set the workspace to create textual references to dropped morphs, and drag and drop the morph on the workspace.

I'm trying to build a GUI, pretty much a beginner.

Here's the fixed code:

acceptDroppingMorph: dropee event: evt inMorph: targetMorph
"Return the dropee to its old position, and add a reference to it at the
cursor point."
| bindingName externalName reference |
(dropee isKindOf: TransferMorph)
ifTrue: [reference := dropee passenger.
externalName := dropee passenger className]
ifFalse: [reference := dropee.
externalName := dropee externalName].
externalName := externalName isOctetString
ifTrue: [externalName]
ifFalse: ['a' , externalName].
bindingName := externalName withFirstCharacterDownshifted , reference identityHash printString.
targetMorph correctSelectionWithString: bindingName , ' '.
(self bindingOf: bindingName)
value: reference.
(dropee isKindOf: TransferMorph)
ifFalse: [dropee rejectDropMorphEvent: evt].
^ true"success"
