[tlaplus] Re: Overriding operator which is used in a temporal property

Pretty much all constant operators are overridden with Java code.  If you are overriding a constant operator, the problem is almost certainly in your Java code.  Try testing it with the "Evaluate Constant _expression_" feature of the Toolbox.  I don't know if it's possible to override a non-constant operator with Java code, but I expect you'd need to know a lot about how TLC works to do it.

Is there any way that I could use an overridden operator in a temporal property? E.g. `prop` is a `PROPERTY` and `MyOperator` is overridden by a Java method.

prop ==

It works when not overridden, otherwise it gives me the following error (using the `TLAPlusOperator` interface)

Error: In evaluation, the identifier mainVar is either undefined or not an operator.

I'm doing this for a personal project and I understand that the evaluation of temporal properties is complex enough that I guess I should not be able to do this, but who knows.
