Calling module params from custom field type

Question

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.

You probably forgot to specify container of the form fields. Your code should be something like

$this->form->getValue('fallBeginning', 'container')

if your field has actual html code like

<input type="text" name="container[fallBeginning]" value="x">

The container value depends on your xml definition, what is the name of fields. For example

<form>
    <fields name="container">
