----------------------------------------------------------
I try to provide a solution to using a uniform way to handle and display
error messages in the portlets.
1. Some helper methods are added in the class BasePortlet, so any portlets that
extend it could use them to add error messages.
eg. getWebMessages(request, response).addErrorMessage(message,
detailedMessage);
2. While rendering the portlets, those messages are generated as html texts in
a hidden block on the html pages.
3. A dojo extension GMessages.js will load the messages and show them on the
header of each portlet. The reason of using Javascript to display messages is
that I wish to show messages on the header of the portlet page, and until
finishing rendering, we could not know how many messages are added by the
portlet.
4. For how to display the messages, I refer to the way used by the deployment
portlet, please check the snapshot attached.
5. I update the class DeploymentPortlet for a demo.
Before trying this patch, dojo plugin should be installed, and make sure the
reference to dojo.js is /dojo/dojo/dojo.js
Plase help to review it, and if it is feasible, I wish to continue to work on
it, and begin to do some changes to existing portlets.
Thanks !

> Currently, different portlets uses different way to show those error messages
> to the end user. We need a uniform way to do it. The simliar issue is opened
> in GERONIMO-2621, but it was closed due to overwork on it in the past.

> days. Thanks !
