Hi Mariano, great job of the release. I've hit this one bug- pool dictionary spelling is checking a collection where it expects a string. Here's an alternative. RBPoolDictionaryNamesSpellingRule>>checkClass: aContext (aContext selectedClass isTrait or: [ aContext selectedClass isMeta ]) ifTrue: [ ^ self ]. aContext selectedClass poolDictionaryNames do: [:poolName | (self check: poolName) do: [ :each | result addSearchString: each; addClass: aContext selectedClass ]] Otherwise refactoring etc all seem good. I get the same test results as other Linux testers. ...Stan -- View this message in context: http://n2.nabble.com/BetaTesting-ANN-Pharo1-0-10507-rc2dev10-01-2-tp4440307p...
