Hello, I'm not sure if this is a bug, but I'd like to check with the Drools experts to see if it is.
I noticed this when creating my custom operator, which doesn't appear to recognize values from Maps, but works fine with non Map based values. I have created a custom comparison operator which takes in a parameter to determine how to execute the comparison logic. So for example, I am able to do the following: id udaycompare[gt] 1 where id is an integer. So for the sake of clarity this is equivalent to "id > 1". Now, when I try to extract an integer from a HashMap called myMap, who has an integer value for the key "someKey", I get an error raised by MVEL: myMap["someKey"] udaycompare[gt] 1 Error thrown: Unable to determine the used declarations. [Error: unknown class or illegal statement: org.mvel2.parsercont...@1d87b85] [Near : {... myMap["someKey"] udaycompare ....}] ^ It appears that Mvel doesn't like getting values from HashMap when working with custom operators. I also tried an alternate way of getting that key from the map as follows: myMap.someKey udaycompare[gt] 1 but i still get the same error. Any thoughts would be greatly appreciated.
