Joomla ACL custom actions - joomla2.5

Question

I'm creating a custom (1.6) component wherein users can book a camp site. Users will be required to log in if they want to use funds/credits that they already have stored. Only certain groups can use these funds/credits.
I have created an access.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<access component="com_propbooker">
<section name="booking">
<action name="booking.create" title="Book Site" description="Allows users of this group to book sites." />
</section>
</access>
and my config.xml file:
<config>
<fieldset name="API Configuration" label="API Configuration">
<field name="google_api_key" label="Google API Key" type="text" size="50" default="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" />
</fieldset>
<fieldset name="Booking Permissions" label="Booking Permissions" description="Set Groups that can book sites">
<field name="booking_permission" label="Booking Permission" type="rules" class="inputbox" validate="rules" filter="rules" component="com_propbooker" section="booking" />
</fieldset>
</config>
It all shows up fine when I click the options button, but no changes are ever saved. It always flips back to "Inherited" when i click the "Save" button.
Thanks in advance for any insight.

Answer 1

Try using permissions as the fieldset name and rules as the fieldname in your config.xml.
Like this:
<fieldset name="permissions"
label="JCONFIG_PERMISSIONS_LABEL"
description="JCONFIG_PERMISSIONS_DESC" >
<field name="rules"
type="rules"
label="JCONFIG_PERMISSIONS_LABEL"
class="inputbox"
validate="rules"
filter="rules"
component="com_propbooker"
section="booking"
/>
</fieldset>
I would also consider using the section name component as it is the default naming. But your needs may be different.
