Expression containing bound variables cannot be bound to a new bound variable in constraint binding.

Issue

When I use a pattern like (*1-1) below in LHS (when part) of my DRL rule, an error like (*e1) or (*e2) occurred when I build the rule.

(*1) Problematic rule

rule "Rule 1"
    when
        Fact1( $value1 : value )
        Fact2( $value2 : (value + $value1) )  // ..... (*1-1)
    then
        ...
end
// "value" is int-type property of the classes above (Fact1, Fact2).

(*e1) the error when I build the rule in non-executable model

[ERROR] Unable to build KieBaseModel:kbase-rules
Variables can not be used inside bindings. Variable [$value1] is being used in binding '(value + $value1)' : [Rule name='Rule 1']

(*e2) the error when I build the rule in executable model
