Subject: Re: [rules-users] How to get value of global variable from one rule to another

   Alexander,

   Remember that the LHS is always evaluated at assert time and RHS is always executed at rule firing time. So, when you change something at rule firing time that you want to cause a reevaluation of the LHS, you must notify the engine calling "modify":

map.put("result",res);
map.put("result2",res2);

modify( map );

    []s

Also, I've tried to map these values in the

rule "AmountsAreNotNull" salience 20
    when
       ...
    then

...

<res, res2 initialization>

map.put("result",res);
map.put("result2",res2);

...           

and check it in the next rule:

rule "CompareValues" salience 10

when

map : Map( keySet contains "result" )

...

"keyset" couldn't found "result" and "result2" mapping

but! when I've checked "keyset" in RHS part of this rule "keyset" HAS proper values of "result" and "result2":

...

then

Iterator k = map.keySet().iterator();
        while (k.hasNext())
        {
            String key = k.next().toString();
            LOGGER.info("Key: " + key + "; Value: " + map.get(key).toString());
        }

...

end

How I can check values of "result" and "result2" in LHS part of rule "CompareValues"?

Thanks,
