[symfony-users] Fatal error: Call to a member function end() on a non-object in ... Hydrator/RecordDriver.php

[joshuacoady]

I'm getting the following error and cant figure out why.

Fatal error: Call to a member function end() on a non-object in .../
Doctrine/Hydrator/RecordDriver.php on line 51

The relevant code in that file is:

    public function getLastKey($coll)
    {
        $coll->end();

        return $coll->key();
    }

It is expecting $coll to be of type Doctrine_Collection, but it is
getting passed an array.

The line that calls that is 218 of Hydrator.php:

$identifierMap[$path][$id[$parent]][$id[$dqlAlias]] = $driver-
>getLastKey($prev[$parent][$relationAlias]);

Query to repeat:

Doctrine_Query::create()
         ->from('Entry e')
         ->innerJoin('e.Data da')
         ->innerJoin('e.MetaData md')
         ->execute();

I included the MetaData relationship because the relationship between
Entry and EntryData is almost the same as Entry to EntryMeta, but the
EntryData causes the error, i.e. if you remove the e.Data da join, the
error goes away.

My schema is as follows:
