I think we have attempted to fix this previously and got it working.

I am trying the latest RCP build and in the XML editor the ctrl + space no longer have content assistance so I can see the list of EIPs to select among.
See screenshot.

I created a new Fuse project and selected the camel-archetype-activemq. And I then opened the camel-context.xml file. And chose the source tab.
And started editing the XML directly.

In the otherwise block I want to add a <log> EIP. But pressing ctrl + space does not show me the EIPs to select. And if I have a EIP selected I cannot see which attributes I can use.
