    Description

      Similar to DROOLS-5216, but occurs when binding the field from a different Fact type.

      Example:

          rule "binding field indexed with square brackets from different fact type"
          when Pojo2($firstItem : simpleInt)
          Pojo($firstItem == integerList[this.integerList.size()-1])
          then
          end
      

      Error:

          Message [id=1, kieBase=binding-field-indexed-with-square-brackets, level=ERROR, path=org/drools/reproducer/rules.drl, line=-1, column=0
             text=Comparison operation requires compatible types. Found int and class java.lang.Object]
      

      The example works fine when compiling without executable model.
