In Seaside 3.2 for Squeak there seems to be a problem with one of the
Pragma preferences:
a PragmaPreference
name: #'GitHub Cache'
value: nil
defaultValue: nil
helpString: ''
localToProject: false
categoryList: #(#Metacello)
changeInformee: nil
changeSelector: nil
type: #String
provider: MCGitBasedNetworkRepository "<-- lookie here, problem"
getter: #cacheDirectoryPath
setter: #cacheDirectoryPath:
Somehow, the 'provider' has been initialized to a
MCGitBasedNetworkRepository whose #basicDescription is a
subclassResponsibility. So the PragmaPreference is unable to access its
#preferenceValue.
I was able to replace it in the debugger with its
subclass, MCGitHubRepository, and that fixed the Preferences panel blowing
up. However, I'm not sure how it got initialized to that superclass in the
first place..
