|Priority||normal||Resolution||no change required|
|Summary||0007851: anAssociation >> and: not understood|
anAssociation = otherAssociation
fails with MessageNotUnderstood Association and:
(0014615 - 1230 - 1384 - 1384 - 1384 - 1384 - 1384)
Thanks for reporting, but there is not enough information for reproducing the failure.
I suspect that this is not a bug in the Squeak code itself, but rather in some 3rd party code.
Generally, the message #and: is not sent, but inlined by the Smalltalk Compiler so as to have faster execution. The only exception is if the argument passed to and: is not a block of code (delimited by Square brackets [ ] ).
If squared brackets have been correctly used like this
self id = anotherObject id and: [self name = anotherObject name]
but that self id = anotherObject fails to return a Boolean (for example if = is implemented with a missing return sign ^ exactly as I intentionally did in above example, it will return self), then there will be a NonBooleanReceiver exception.
To trigger a MessageNotUnderstood exception with #and: as the not understood message, one must have forgetten the square brackets, like this
= another object
self id = anotherObject id and: self name = anotherObject name
Then the fact that it is Association (presumably, it's a class) which receives #and: means that there is yet another error cascaded.
One must send and: to a Boolean, with a block argument.
