Re: [rules-users] Accessing maps (hashmaps) keys and values in rules
Denis,
If you are using latest build from trunk (I'm not sure it already works
in MR3), you can use a simplified MVEL syntax:
when
Person( address["business"].phone == "99999999" )
then
...
end
Although, the above will be converted into an inline-eval. Not as bad as
a top level eval, but still more costly then using regular fields.

2007/7/19, Ryan, Dennis (Dennis) <dennisryan(a)avaya.com>:
We are using Maps (HashMaps) in our rules and the only way we have found
to access keys and values in the Map in the "when" clauses is thru use on
eval() which I know is a big no-no by rules purists. Is there a better way,
maybe some shorthand I'm not familiar with to deal with Maps in the when
clause?
Thanks,
Dennis
