QueryDSL: Struggling with syntax on how to bind for a sub-list field with QList [DATACMNS-1298]

GT opened DATACMNS-1298 and commented

I apologize as I am little confused if this is a QueryDSL issue or else a Spring QueryDSL extension issue. I have explained the issue in QueryDSL github forum -

querydsl/querydsl#2293

To add further, I am using those generated class of QType with Spring Data Web support. With that class structure, I am unable to pass requestParameters as -

emails.email.value=johndoe@rocketmail.com
neither
emails.value=johndoe@rocketmail.com

Both of above fails because of invalid field on QList type as emails type is QList in generated code.

If i just use emails.value = johndoe@RocketEmail.com

then i am forced to register a String to List<Email> converter which i feel like shouldn;t be required.

My API method is very simplistic -

public ResponseEntity<Users> searchUser(@ApiIgnore @QuerydslPredicate(root = User.class) Predicate predicate) {
        if (predicate == null || (BooleanBuilder.class.isAssignableFrom(predicate.getClass()) && !((BooleanBuilder)
                predicate).hasValue())) {
            return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
        } else {
            Users result = StreamSupport.stream(this.userRepository.findAll(predicate)
                                                                   .spliterator(), false)
                                        .collect
                                                (Collectors
                                                         .toCollection(() -> new Users()));
            return ResponseEntity.ok(result);
        }

Appreciate any guidance on how can I bind to sub-lists which are generated as QList and not as ListPath

Fwiw, we were able to avoid the use of QList by hiding the some of unrelated model classes which were extending from ArrayList and hence forcing code generation to use QList. Once that part is taken care of, codegen is now generating proper ListPath as expected,

However, there's an issue w/ ListPath that makes it unusable beyond default "in" clause or binding,
