Hi!! I started this afternoon to see a bug on class bindings on trait methods. This one: https://pharo.fogbugz.com/f/cases/11756/Reshaping-a-class-breaks-classBindin... Now, after playing and moving around that, I noticed that the problem is worse: 1)Create Class A. 2)Create method A>>m1. 3)Create method A>>m2. 4)reshape the class (e.g. add an inst var) Then: (A>>#m2) classBinding == (A>>#m3) classBinding ==> false!!! The problem is caused because the recompilation of the methods is taking place in a class that is not yet installed in its environment (the Smalltalk system dictionary in this case). The installation of the class takes part after the reshaping+the recompilation. Then, when the methods are compiled, the binding is not available for them and new bindings are created. Would someone with more idea on the new class builder give some advice? Cause I'm a bit lost in the new class builder code :) Tx, Guille
