To all Java developers: can you imagine coding Java without code completion in your favorite IDE? - No way! - Yet, this is how we've been coding for years with Nuxeo components and extension points in Eclipse. Sun started to write this new feature in Nuxeo IDE: an extension to the Eclipse WST XML Editor for completion proposals based on the Eclipse JDT model and XMAP introspection. Through demonstrations, Sun will introduce you to the new features he has implemented: existing extension point proposals, extension completion based on descriptors, documentation in tooltips, etc.
