ExpressionEvaluatorResult (drools-scenario-simulation-backend 7.57.0.Beta1 API)

```
public class ExpressionEvaluatorResult
extends Object
```
This DTO holds info related to an expression evaluation. - successful: field represents status of involved evaluation (successful or failed); - pathToWrongValue: a list which contains the steps to describe the wrong value. In case of nested object or collections, can require multiple steps (eg. Author.books). In case of a list, conversion is to report the Item number (eg. Author.books.Item(2).isAvailable) - wrongValue: The actual wrong value Instantiated objects can be accessed only to retrieve the success status and to generate an error message, if evaluation failed, based on wrongValue and its path.
