Old thread but in case anyone else comes across it.

It is possible to use the PortletPreferences section of the API to store preferences for the portlet. In particular, if you are already creating custom jsp hooks/code for the portlet then all you need to do is also include the logic to retrieve them and use them as required. Check out the PortletPreferences table in the database and the PortletPreferenceLocalServiceImpl (and related classes) for the API stuff.

Hello,

You should try to have a look at the ExpandoValueLocalServiceUtil class. I think you will be able to manage your custom field...

About your portlet preferences, you have to add the following to your portlet.xml:

<portlet-mode>edit</portlet-mode>

Then, the main class of your portlet has to implement PortletListener. You will have to switch portlet modes (view - preferences) in the overrided method handleResourceRequest...

Hope I helped you...

Best,
Nicolas.
