I'm having trouble in getting the singleton pattern to initialize a instance variable in smalltalk. (here is a link to another implementation for clarification)
this is what I have:
new
^UniqueInstance ifNil: [UniqueInstance := self basicNew.
UniqueInstance: instanceVar := Object new. ].
that last line (UniqueInstance: instanceVar := Object new.) doesn't work, but that's basically what I need to do: instantiate instanceVar as an Object before returning UniqueInstance back to the caller.
Notice that this 'new' method is used as a classinstantiation, and that libraries is a instance variable of UniqueIsntance (the isntance of the wanted class).
Can anyone point me in the right direction?
