ForeignCollection auto load with queryRaw()

I have a Card class, which has an eager ForeignCollection in it. I have to query for the instances of this class with a Dao.queryRaw(), because my SELECT is too complicated to be built with a simple QueryBuilder (see my other question). This is how i query and build my objects with RawRowMapper:

GenericRawResults<String[]> rawResults = getCardDao().queryRaw(statement);
List<Card> results = new ArrayList<Card>();

for (String[] row : rawResults) {
    results.add(getCardDao().getRawRowMapper().mapRow(rawResults.getColumnNames(), row));
}

rawResults.close();

Unfortunately when i try to get the ForeignCollection on my objects, it returns null. If i query the objects with a simple Dao.queryForFirst, the ForeignCollection is OK.

I have had the same problem today. My solution has been to call something as 

dao.refresh(<Card object>)

for every object returned by the queryRaw function (and accumulated into "results" list). This do the trick for me, reloading objects from DB with filled foreign collection.
