Interestingly enough, the same question was answered in an Iliad thread...
A method that does what you want is present in Seaside:
Signal extend [
resumeContext [
^resumeBlock outerContext home
]
]
then you can do
[Notification signal]
on: Notification
do: [:ex | ex resumeContext backtrace]
Actually a nicer backtrace can be obtained with
Signal extend [
resumeContext [
| context |
context := resumeBlock outerContext home.
[context isInternalExceptionHandlingContext]
whileTrue: [context := context parentContext].
^context
]
]
I'm adding this to the standard library, though under the name
#signalingContext.
