Description of my issue:
There is an error in front-end submission (bugfix), if submission do not have any custom fields. This part of the components/com_hotspots/models/hotspot.php prevent form to be submitted (error about unknown variable, or something like this), failed with fatal error.

public function getForm($data = array(), $loadData = true)
{
// Get the form.
$form = $this->loadForm('com_hotspots.marker', 'marker', array('control' => 'jform', 'load_data' => $loadData));

// Make sure that the custom fields are part of the form
/******** ------ THIS IS THE BAD PLACE. I commented to make my own site running, but had to be checked and repaired.

// $customFieldsModel = $this->getInstance('Customfields', 'HotspotsModel');
// $form->load(HotspotsHelperCustomfields::generateFormXML($customFieldsModel->getItems($data['catid'])));
