java - JPA IN expression of collection not working -

hi folks,

    list<integer> typelist = new arraylist<integer>();     typelist.add(1);     typelist.add(2);     expression<collection> expr = criteriabuilder.literal(typelist);     path<integer> path = root.get("type");     path.in(expr); 

the generated sql restriction type be:

type=(1,2)  

instead of

type in (1,2) 

the following works

path.in(typelist)  

works. problem code? in our case, have convert collection expression.

edit:

 predicate  in(expression<?>... values)   predicate  in(expression<java.util.collection<?>> values)  

it seems invokes first method (wrong). how fix it? seems jpa defines many overloaded methods ambiguous itself.

edit:

how create expression collection? literal(values) maybe not right way. jpa might think single value, , replace in equal comparator.
