saveAction stores empty object

Question

Whenever I fill a form and click "Save", magento doesn't get the form data. It just saves an empty object in the database. I can't figure out why. Here's my form and file structure:

Answer 1

I found out what the problem was. In my form the fields' names weren't the same as the table columns. If I have a column "title", then my field should be:

$fieldset->addField('title', 'text', array(
        'label' => $this->__('Title'),
        'class' => 'required entry',
        'required' => true,
        'name' => 'title',     // MUST match the table column!!!
    ));
