Hi J.S, Thanks I added your test case to the tree as actor/lib/test/auto/RecordUpdater2.xml
The model has a RecordUpdater with three inputs. Const ---->|| Const2 ---->||---> Const3 ---->|| The last input port of the RecordUpdater (associate with Const3) has a type constraint that is set to int. If I set the type constraint of the third input to unknown and set the output of Const3 to int, then the problem goes away. There is a bug here, but I'm not sure of an easy fix. I cleaned up the error message so we now get: ptolemy.kernel.util.InvalidStateException: Port ".RecordUpdater2.RecordUpdater.id" of type "int" in an InequalityTerm is not settable. If the port is an input and has a type constraint, try removing the type constraint and possibly placing it on the output. at ptolemy.graph.InequalitySolver._addToClist(InequalitySolver.java:324) at ptolemy.graph.InequalitySolver.addInequality(InequalitySolver.java:107) at ptolemy.graph.InequalitySolver.addInequalities(InequalitySolver.java:93) at ptolemy.actor.TypedCompositeActor.resolveTypes(TypedCompositeActor.java:259) at ptolemy.actor.Manager.resolveTypes(Manager.java:993) at ptolemy.actor.Manager.preinitializeAndResolveTypes(Manager.java:890) at ptolemy.actor.Manager.initialize(Manager.java:572) at ptolemy.actor.Manager.execute(Manager.java:320) at ptolemy.actor.Manager.run(Manager.java:1044) at ptolemy.actor.Manager$3.run(Manager.java:1085) The error message is a too verbose, but it might help the next person. Maybe someone else has an idea here? _Christopher -------- Hi, I found a bug in RecordUpdate. When you add an input port and enforce a "Type" (e.g. string, int, etc.) it breaks with the following stack: ptolemy.kernel.util.InvalidStateException: Variable in an InequalityTerm is not settable. at ptolemy.graph.InequalitySolver._addToClist(InequalitySolver.java:308 ) at ptolemy.graph.InequalitySolver.addInequality(InequalitySolver.java:1 06) at ptolemy.graph.InequalitySolver.addInequalities(InequalitySolver.java :92) at ptolemy.actor.TypedCompositeActor.resolveTypes(TypedCompositeActor.java:259 ) at ptolemy.actor.Manager.resolveTypes(Manager.java:989) at ptolemy.actor.Manager.preinitializeAndResolveTypes(Manager.java:886) at ptolemy.actor.Manager.initialize(Manager.java:572) at ptolemy.actor.Manager.execute(Manager.java:320) at ptolemy.actor.Manager.run(Manager.java:1040) at ptolemy.actor.Manager$3.run(Manager.java:1081) The original test for RecordUpdater (ptolemy/actor/lib/test/auto/RecordUpdater.xml) wasn't able to find it because it did not enforce any type. The test file I send in attach. to this email is just a small modif. of it, trying to force an int input.
