I've created a module which has a number of settings, one of which uses a custom field type defined within my module. The custom field essentially generates a dropdown list which is populated with data.
To decide which data should be added, though, I need to access some other parameters in the settings file. I've tried using
$this->form->getValue(param) where param is the name of the field I'm trying to access, but it returns nothing.
Couldn't find anything specific in the documentation for this.
