I am encountering the following problem: I start CBC through AMPL and can see that the call from AMPL works correctly (correct dimensions and correct objective after finishing optimization). However, AMPL does not receive the updated values from CBC, the AMPL's variables remain set to the values that they had when calling CBC.
I tried the following versions of CBC: 2.2, 2.2.2, 2.3.2 and 2.4 and always had this problem.
