Expected behavior

The DTO compiler reports an error when the filter class does not match the target entity type.

Actual behavior

Compilation of the DTO succeeds. The error surfaces later from javac, in generated code:

BookDeepView.java:115: error: incompatible types: AuthorFilter cannot be converted to FieldFilter<BookTable>

Description

DtoGenerator (KSP) parses the generic argument of KFieldFilter and compares it against the target entity type, throwing DtoException on mismatch. The APT implementation constructs the same GenericParser against FieldFilter and discards the result. The check is missing on the Java side; the error only surfaces from javac, at a line in generated code.

Reproduction steps

dto

export org.babyfish.jimmer.sql.model.Author

import testpkg.configurations.AuthorFilter

BookWithFilter {
    !filter(AuthorFilter)
    books {
        authorFullNames
    }
}

entity

@Entity
public interface Author {
    @ManyToMany(mappedBy = "authors")
    List<Book> books();
}

@Entity
public interface Book {
    @ManyToMany
    @JoinTable(
            name = "BOOK_AUTHOR_MAPPING",
            joinColumnName = "BOOK_ID",
            inverseJoinColumnName = "AUTHOR_ID",
            deletedWhenEndpointIsLogicallyDeleted = true
    )
    List<Author> authors();

    @Formula(dependencies = {"authors.firstName", "authors.lastName"})
    default List<String> authorFullNames() {
        List<String> fullNames = new ArrayList<>(authors().size());
        for (Author author : authors()) {
            fullNames.add(author.firstName() + "-" + author.lastName());
        }
        return fullNames;
    }
}

filter

public class AuthorFilter implements FieldFilter<AuthorTable> {

    @Override
    public void apply(FieldFilterArgs<AuthorTable> args) {
        AuthorTable table = args.getTable();
        args
                .where(
                        Predicate.and(
                                table.firstName().ne("Alex"),
                                table.lastName().ne("Banks")
                        )
                )
                .orderBy(
                        table.firstName().asc(),
                        table.lastName().asc()
                );
    }
}
