This is interesting, after a long time, 11g is has introduced new feature called Events in Object navigator
I assume that we can use the same for Chat application, which we can fire the events from back-end.
Need more R&D on this area to use this feature.

Integration with JavaScript in the surrounding Webpage – Using this, we can use multiple forms on the same HTML if it is required
Using this, we can pass forms value to HTML and set different title/values on the base HTML – need to work on more
Forms11g provides java classes where you can define appearance/behaviour of buttons, text area etc. This will be very useful for developers, who is looking for change in the User Interface.
Thanks to Oracle for their extended support of Forms11g up to 2017
