    Hello,

    1) why it's not allowed to build an expression like this
       --> see qual_2 (error message: "Can't resolve path component:
    [Category.id]")

    ...
    Expression qual_1 = Expression.fromString(SomeObject.NAME_PROPERTY + "
    likeIgnoreCase '%" + name + "%'");
    Expression qual_2 = ExpressionFactory.matchExp("hasCategory.id",
    categoryId);
    qual_1 = qual_1.andExp(qual_2);
    SelectQuery query = new SelectQuery(SomeObject.class, qual_1);
    ...

    -id is the PK-Column of category table

    2) what is the best solution in this cases.

    Thanks for help
