Default value is not working if there is a bound model

[cboelter]

I'm using the Form class with a bound Contao Model. If I want to set the default value of a field in the dca configuration like this:

'salutation' => [
  'label' => &$GLOBALS['TL_LANG']['xxx']['salutation'],
  'inputType' => 'radio',
  'options_callback' => ['xxx', 'getSalutationOptions'], // returns ['mr', 'mrs']
  'default' => 'mrs',
  'reference' => &$GLOBALS['TL_LANG']['xxx'],
  'eval' => [
    'mandatory' => true,
    'step' => 1,
  ],
  'sql' => ['type' => 'string', 'length' => 3],
],

The default value will be overwritten every time with the model value, even it is currently empty.

To fix this, I have changed this line: https://github.com/codefog/contao-haste/blob/master/library/Haste/Form/Form.php#L414 to the following:

if (!$arrDca['ignoreModelValue'] && $this->objModel !== null && $this->objModel->$strName) 

So the model value is only used, if there is a value for the field. Is this a bug or is there another way to set the default value?

If you bind the model, the model is the master. Default values should be represented by the model too, otherwise what happens if I do something like this:

$model = new FoobarModel();

echo $model->salutation;

? It will not show mrs but it should ;-)
