Using 3.6, there is one class I cannot generate hashCode/equals for. Nothing happens (the dialog where I can pick what fields to involve does not show), and the following is logged: eclipse.buildId=I20100608-0911 java.version=1.6.0_20 java.vendor=Sun Microsystems Inc.

> there is one class I cannot generate hashCode/equals for. Could you attach that or strip down to a test case?
From looking at the code, I don't see how this could happen. Please reopen with an example.
