Hi Romain. I was testing a little OCompletion in Pharo 1.1 and I found a bug in ECUntypedModel >> initializeSelectors as it is doing: [ Smalltalk keysDo: [ :each | selectors add: (ECGlobalEntry contents: each type: #globalVar) ]. Smalltalk, SmalltalkImage and SystemDirectory were refectorized. Running OCompletion tests, I have one red. I changed to: [ Smalltalk environment keysDo: [ :each | selectors add: (ECGlobalEntry contents: each type: #globalVar) ]. (notice I added environment) and with this, the test is green and OCompletion seems to be working. What do you think? can I commit ? Cheers Mariano
