[rules-users] Guvnor guided rule and nested objects

[Héron Nicolas]

Hello, 
for the first rule, the Jira is
https://jira.jboss.org/jira/browse/JBRULES-1929
and you have to wait that my patch is applied and you will be able to do
all you want
look at
https://jira.jboss.org/jira/secure/attachment/12325575/FinalModification.jpg

for the second part of you question, did you try with class Double
instead of standard type double.
For example, if a variable is boolean, than no listbox appears. 
But if you use Boolean, then it works, a listbox appears and you can
select everything
regards
Nicolas Heron
