Nice catch! I actually assumed that the styler resets its state before calling into the model. :-O

Best,

Christoph Thiede uploaded a new version of Tools to project The Trunk:
http://source.squeak.org/trunk/Tools-ct.1091.mcz

==================== Summary ====================

Name: Tools-ct.1091
Author: ct
Time: 15 December 2021, 8:01:22.087022 pm
UUID: 5b6f6413-b247-5642-8890-68b2ccfacbdc
Ancestors: Tools-ct.1089

Fixes a slip introduced with BlockClosureInspector. Make sure to reset the styler's workspace variable after switching to a different kind of inspector (i.e., in the context of a debugger). Otherwise, you might see error messages such as "MessageNotUnderstood: Inspector>>hasBindingOf:". :-)
