Re: [rules-users] MVEL and Maps
create declared types and then use a transformation tool to marshal
those maps into the internal type declarations. You can look at the
pipeline's jaxb and xstream for examples of how this works.

Hello,
I'm feeding my working memory with Maps (unfortunately, this is a
requirement and I can't use beans).
To access the values in this maps I use the following MVEL expression :
Map ( this["airportCode"] == "GIG"
, this["numberOfPassengers"] > "1"
, this["class"] memberOf ("BUSINESS", "FIRST") )
And it works fine, except for dates where I get a ClassCastException,
even tough I'm using the right pattern:
Map ( this["departureDate"] > "07-Nov-2009" ) --- fails
Is there anything I need to do to make the dynamic cast of dates work,
in this particular case?

Morever, I get NPEs if there's no value for a given key. For example,
the expression Map ( this ["name"] == 'Leonardo' ) would fail if
there's no entry with "name" as the key.
Any help is welcome!
Thanks in advance,
Leo.
