Description of problem:
Let's say an enumeration is defined in a class in the following fashion:
~~~
public class EnumeratedFact {

     private EnumeratedFact.TestEnum enum;
     private String firstName;
     private String lastName;
...
     public enum TestEnum {
     ...

     }
...
~~~
Now, in order to use it to draft a rule through Guided Rule Editor while attempting to "Import" the enumeration in "Config" tab, the enumeration is displayed having the "$" sign in the class name instead of "." . Java uses "$" internally for inner classes, hence Business Central should use "." instead. Now, while writing the rule in form of a "Add free form drl" option, where the rule is written that uses the enurmeration having the name like "EnumeratedFact.TestEnum.XYZ" . As soon as the rule is saved and the Guided Rule Editor refreshes the rule , it converts the enumeration appearing in the form of having a "$" sign in it's class name, like "EnumeratedFact$TestEnum.XYZ". This causes a validation error for that rule in Business Central.

[Error: unable to resolve method using strict-mode: org.drools.core.spi.KnowledgeHelper.EnumeratedFact$TestEnum()]
[Near : {... EnumeratedFact$TestEnum.XYZ ....}]
~~~

Unfortunately, there doesn't seem to exist any workaround for this issue, except of using DRL editors to write a rule with such an enumeration.
