To whom can answer me Working with Pharo 3.0 I noticed for a while that I could not recover class definitions (do it's) from the "Recent Changes". I also lost class comments on file-out / file-in . For the second problem I made the following test: 1. take a fresh Pharo 3.0 image (bundle for Mac OSX from Aug 29, 2014) 2. create MyClass with a class method and a comment. 3. file-out MyClass 4. remove MyClass on remove of MyClass I get an exception: https://www.dropbox.com/s/unq89t84tq7r60b/removeClass.tiff?dl=0 5. file-in MyClass The class is there - no error But: With the same exception in other images the comment is missing after file-in. Is this known? What does the exception mean? -- Hartmut Krasemann⨠Königsberger Str. 41 c â¨D 22869 Schenefeld⨠Tel. 040.8307097⨠Mobil 0171.6451283⨠krasemann@acm.org
