XPages should have native access to RDB data. This will allow the use of external SQL data in views and forms in conjunction with Notes data. Moving Domino Designer to Eclipse was a big step forward in opening up the propertairy technology of the Lotus Notes development platform. The next step to wider acceptance of Lotus Notes as an application development platform is to allow the tool to easily integrate with other systems in a corporate environment.
I know this has been mentioned as a future enhancement for XPages but I feel we need to drum up support to make sure this happens.
