PropertyChangeSupport in ADF Mobile

Question

I'm working with ADF Mobile - altogether easier and more powerful than I thought - much faster development than with the Android SDK, and multiple device support thown in.
I'm seeing in the bean samples that PropertyChangeSupport is used for every bean variable on setting (via the firePropertyChange method, but also with the fireProviderRefresh and fireProviderCreate methods).
The ADF API has scant documentation:
"This is a utility class that can be used by beans that support bound properties. You can use an instance of this class as a member field of your bean and delegate various work to it."
Is this a new way to work with bean values? It appears to be mobile only (in the adfmf package), so it is a different way to handle this?
When do I use this? Which methods do I call?
Is there more documentation?
Thanks,
Ed.

Hi,
this is normal JavaBean development in which properties notify listeners about change (thus bound properties). In the ADF Mobile case the framework listens and you can use this to refresh a component. See http://www.oracle.com/technetwork/developer-tools/adf/learnmore/m02-dynamicallyshowhidecomponents-1915399.pdf where I used this to dynamically show/hide components. So to answer your question: yes its spcific to ADF mobile and not required in Web ADF. But then its not specific because you would use the same in Java desktop UI development too.
