[rules-users] Issues with float/double constants

Hi, I have two issues with float/double constants. In both cases dialect is set to MVEL Issue 1 If I use a comparison operator with the Double value it doesn't seem to work correctly w/o brackets in the right part of the expression: Example: I have a condition like: NumberVariable( owner == $a, name == "PTI", value > 0.5) In the class NumberVariable the method getValue() is declared as follows: public Number getValue(); In the working memory I have an instance with name == "PTI" and value == 0.9633716684527102 ( actual type of the value is Double). And the rule consequence is not executed. If I change it and add brackets around the constant everything works correctly: NumberVariable( owner == $a, name == "PTI", value > (0.5) ) There is similar example in drools documentation (w/o brackets): Cheese( type == "stilton", price < 10, age == "mature" ) I assume that in this example the property has a primitive type and in my case autoboxing is involved, but why brackets are necessary in my case? Issue 2 I have a rule: rule "Determine min PRI for for PROD2" ruleflow-group "budget_calculated_variables_appl" when $a: RetailApplication( ) StringVariable(name=="prodid", value matches CONST.PROD2) then insert(new NumberVariable("minPTI", 0.6, $a)); end Initially I had only one constructor for NumberVariable: public NumberVariable(String pName, Number pValue, Object pOwner) But MVEL couldn't find this constructor when "then" part was executed (runtime exception). The problem was solved when I added another constructor: public NumberVariable(String pName, float pValue, Object pOwner) Java compiler accepts identical code when only first constructor is there: NumberVariable nv = new NumberVariable("minPTI", 0.6, null); Drools version: 4.04, Java version: 1.6 Thanks, Andrey.
