[rules-users] Guvnor meant for business users?

[nxg912]

Hello All,
We are evaluating Drools for our production implementation with special
focus on the fact that it would let less technical people be able to work
effectively with business logic (once developers provide them with a data
model). We are relatively new to Drools and our impression has not been too
good specially around Guvnor (given that DRL is meant for developers and DSL
is nothing but a simple extension for DRL which business analyst won't be
able to use). Has anyone here used Guvnor or DSL effectively for a
reasonable size implementation?

With Guvnor we are facing some issue which are very basic and Guvnor comes
across as a immature web application from the UI perspective (Because of
being less user friendly, incomplete messages for error situations etc).
Also, its difficult to find help on some simple scenario like the following,

We have a "Customer" class and a "Agreement" class with one to many
relationship. We are trying to build a simple rule that if an "Agreement"
has missed payment (indicated by a boolean inside Agreement class), mark
that "Customer" as bad customer by setting the boolean field inside the
"Customer" class. Its a simple scenario to be build in DRL but how to we
implement this under 'WHEN' and 'THEN' section in guided editor without
using the DRL free forms? It shows an error message that access/write
property for Customer not available in Agreement.

Any thoughts or help in these matters will be really helpful. Also, if there
are some helpful links around Drools that would help getting started with
the implementation, that would be great!

Thanks in advance.
