In revision 12848 of the 1.7 branch, I have to manually add the prefix path for the file validators like this:

$element = new Zend_Form_Element_File('foo'); $element->addPrefixPath('Zend_Validate_File', 'Zend/Validate/File', 'validate'); $element->addValidator('Count', false, 1);

Otherwise, I get this exception: Zend_Loader_PluginLoader_Exception: Plugin by name 'Count' was not found in the registry; used paths: Zend_Validate_: Zend/Validate/

I'm assuming the prefix path used to be set automatically, because it's not mentioned in the documentation: http://framework.zend.com/manual/en/…
