----------------------------------------------------------------

I've documented more details on Google Groups @ https://groups.google.com/forum/?fromgroups=#!topic/drools-usage/S27hlbLoXeM.

I have attached my latest DRL test files.  The test case is relatively the same with the exception of passing in my custom map, a class, or just a HashMap directly.

It seems that if I use a HashMap directly I can make progress but after don'ing I have 2 map facts in WM vs. the 1 I would expect.

Output using a Map directly:

{quote}Rule 1
Rule 2A: 1.0 (before don)
Rule 2B: 1.0 (after don)
Rule 2C: 1.0
Rule 2D: 1
Rule 3: 1.0
Rule 3A: 2
Rule 4A: 2.0
Rule 4B: 1.0
Rule 4A: 2.0
Rule 4B: 1.0
Rule 5: 3.0
Rule 3: 1.0
Rule 3A: 2
Rule 4A: 2.0
Rule 4B: 1.0
*Model: 2*
Trait: 1{quote}

At this point, I am completely out of ideas...

>         Environment: * Alpine Linux (in a Docker container)
> * Oracle JDK 8

> * Spring Boot v1.5.4.RELEASE (though testing without any Spring)

> It appears that after don'ing the trait the map-based fact it is proxying disappears (or gets retracted).
> There does not seem to be any issue using the trait properties to access the model properties.
> We are trying to use the model, mostly for constraints and updates, then within the rules apply and use traits to give us a stronger-typed fact and easier rule constraining.
