Hi

I'm using Drools and Guvnor in our project. We have the following Data Model
(simplified):
- Object C
-> has a List
-> has a List

I need to build an easy to edit web decision table in guvnor. We need the
table to fill a dropdown list (Object B) in dependency of another dropdown
list (Object A), when for example creating a new Object C on a form. The
table should look something like this:

[Object A] [Object B]

Test A1     Test B1

                Test B2

                Test B3

Test A2     Test B4

Test A3     Test B5

                Test B6

Test A4     Test B7

                Test B8

                Test B9

                Test B10

...so when a User creates a new Object C (Create-Form) and select on for
example "Test A3" in a dropdown list (Object A), Drools should be firing and
result "Test B5" and "Test B6", which then can be filled in the second
dropdown list (Object B).

How can I achieve such a scenario? We have already Drools Guvnor in use and
the requirement is, to have such a table to easy edit the dependencies of
this two dropdown lists.

Some thoughts:
- Is there a way to fill Objects in a List as a Action-Column in a web
decision table?
- Is there a way to add Objects to a List (global variable) in a web
decision table?
- Is there a way to achieve this with rule templates?
- Are there other ways to achieve this?

Thanks for your help.

Kind regards,
Peter
