Re: [rules-users] Retrieve values from a Map
If you need the value on the RHS, you can use s.th. like
lang.get("Japanese")
or
$c.getLanguage().get("Japanese")
If you want to match the value in a subsequent pattern, you
could use an eval() or similar; since you don't show what you
need the value for, I'll not enumerate all possibilities.

I am new to drools and currently using version 5.1 for my testing.
I am facing an issue with retrieving a value from Map if a key is present
In my drl if i do this
$c : Client (language contains "Japanese" , lang : language ->
(language.get("Japanese").equals("Expert")))
it works ...but if i want to retrieve the value of the key i am not sure how to
go about it . I tried various approaches but none of them worked
i would like to do something like
$c : Client (language contains "Japanese", $langValue :
language.get("Japanese"))
Can some one please guide me how to go about it .
