>             Project: Drools
>          Issue Type: Bug
>          Components: core engine, executable model
>    Affects Versions: 7.31.0.Final
>            Reporter: Toshiya Kobayashi

> Having a constraint like
> {code:java}
>     Person( name == "Toshiya" )
> {code}
> is not really the same thing as
> {code:java}
>     Person( "Toshiya" == name )
> {code}
> In the second case not only you don't have property reactivity, but also you don't have indexing. This an inconsistent behaviour and hoping to fix it with a "normalization" phase where the second constraint got rewritten like the first before being analyzed by property reactivity and indexing.
