[rules-users] Question on contains operator with integer

[cwolfinger]

Hello - I have a question on how to a contains operation with primitive
values.  What I have is a message that has a field called intTest that is a
List<Integer>.  If i do an intTest contains 4 check, then check compiles but
it never matches.  However if I do an eval it does work.  Does anyone know
how to use a primitive in a contains.


Here is a sample of the rule:

package com.sample
 
import com.sample.DroolsTest.Message;

rule "Test" salience 9999
	#when Message( eval(intTest.contains(Integer.valueOf(4))))
	when Message( intTest contains 4)
	then
	System.out.println("Found 4");
end
