Re: [rules-users] Trying to compare variables of two objects, not working. (compiles, but not desired result)

5.3.0 and 5.4.0.Beta2: Comparing int and Integer fails unless the
traditional (up to 5.1.1) "return value" construct - parentheses
around the expression - is used:
lineItemId == ($lineItem.getID()) // OK
lineItemId == ($id) // OK with $id bound as LineItem( $id: ID> 0 )
Do you mean that this is a new feature since 5.3 and comparing Integer
worked with values prior to this version ?
This is confusing, as I really though that drools uses equals instead of
== for String and all "primitives as Object" like Long, Integer and so
on ...
And this is strange, as in Java, == works with values for Integer, and
drools is in java ...
And I never faced this problem before, and I am pretty sure that I did
use Long in tests ... well in fact I was sure before this mail, less now ...
Can you develop more on why this is done this way, and why this is not
behaving like java ?
