After upgrading to symfony 0.7.1581, the propel-build-model task is broken, failing with the following error:
ERROR: symfony - You must create a schema.xml file.
As Gimler in the forum correctly pointed out, this can be fixed by a simple change in {$data_dir}/symfony/tasks/sfPakePropel.php. Line 132 should be changed from:
$schemas = pakeFinder::type('file')->name('*schema.yml')->relative()->in('config');
to:
$schemas = pakeFinder::type('file')->name('*schema.xml')->relative()->in('config');
It seems that the problem is a typo, causing pake/propel to look for a schema.yml, rather than a schema.xml. Upon changing this line, the task works perfectly again.
