Why is the protected function _populateState() in the /admin/models/helloworld.php file? It doesn't appear in the original helloworld.php model file, and there isn't any indication as to the purpose of this function aside from the annotations within the function, which I don't fully understand.
Section about admin/views/helloworld/tmpl/edit.php is not the same as in file present in archive.
I have expanded the helloworld component to have several other fields now, and set some of them to required="false" in the /models/forms/app.xml file. I still get "invalid field" when I leave the input box empty. Any ideas?
