[Pharo-project] problem with Dictionary and KeyNowFound

by Mariano Martinez Peck

So...it seems Pharo1.3 change Dictionary to throw KeyNotFound instead of Error. Now, my image freezes with a loop. I would appreciate some help. I couldn't really analyzed the problem. Fileine both FLPerson.st and ATest and run the test testDictionaryRehash. In such test, a the end there is a self shouldnt: [aDictionary at: newPerson1] raise: KeyNotFound. which raises the debugger pre-popup. if I try to click on the popup... -> loop/freeze. You can interrupt it and see more or less what is happening. Camillo, can you take a look? Thanks -- Mariano http://marianopeck.wordpress.com
