1. Create web application with "JSF" framework. 2. Open XML view of faces-config.xml. 3. Write '<' after <faces-config> tag. 4. Press Ctrl+Space. Result: Code completion window is displayed and JavaDoc window is shown for components, but for all of them message "No ducumentation found for this item." appears. For a lot of their children the same.
I do see all 'Javadoc from source' appear for all elements. Please see the attached screenshot. BTW, the Javadoc button will never be there if that's what you mentioned. It's coming from 'external' Javadoc zip that we will not support.

On your screenshot you can find string "No ducumentation found for this item." under "Element: application" string. I've talked about it. Is it normal?
Yes, it's a never planned feature. I will put this in the future feature plan.
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
