Subject [jira] Updated: (GERONIMO-4353) An uniform way to show error messages on the console
Date Tue, 14 Oct 2008 16:37:44 GMT


Ivan updated GERONIMO-4353:

    Attachment: snapshot.JPG

    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 the
page for each portlet. The reason why using js to display messages is for we wish to show
messages on the header of  the portlet page, and until finishing rendering, we could not which
messages are needed to display.
4. For how to display the messages, I refer to way used by the deployment portlet.
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.
> I am trying to provide a solution, and will provide a demo in the next few days. Thanks
