Propel and Collection Methods

Question

I am developing a PHP app with Propel ORM as a model. It's installed via Composer and all classes are auto-loaded correctly. I can create querys, access database and retrieve data to populate my page. Nice.

But I'm having trouble with some methods like isLast(). According to documentation, you can use it as follows:

$books = BookQuery::create()->find();
foreach ($books as $book){
  if($books->isLast()){
    // Do something
  }
}

I can't even replicate this simple example. I have simplified my code in order to see if it works (with my own tables and columns names):

$provincias=ProvinciasQuery::create()->find();
foreach($provincias as $v){
  echo $v->getProvinciasNombre(); // This works!
  if($provincias->isLast()){ // This doesn't :(
    // Do something
  }
}

I get always the same error:

Fatal error: Uncaught exception 'Propel\Runtime\Exception\BadMethodCallException' with message 'Call to undefined method: isLast' in /path/to/my/app/vendor/propel/propel/src/Propel/Runtime/Collection/Collection.php on line 558

Same happens with other methods like isEven(), isOdd() or isFirst(). Method isEmpty() seems to work fine.

Any help would be appreciated.

Found a solution here:

$books = BookQuery::create()->find();
$booksLoop = $books->getIterator();
foreach ($booksLoop as $book) {
  if ($booksLoop->isFirst()) echo "First";
}

Official documentation for Propel 2 is outdated. I have already filed an issue at github: https://github.com/propelorm/Propel2/issues/1314
