To reproduce; create the 'camel-activemq' archetype via New
> Project> Fuse IDE Project ... > (type "act" in the filter to find it).
Then run it (select the camel-context.xml and right click -> Run As -> Local Camel Context.
Browsing the endpoints in JMX Explorer you should see some messages; if not drag & drop some of the src/data/message*.xml files onto some of the camel endpoints then browse them.
Select an endpoint thats got messages in the Messages View in Fuse perspective - then select a message. Does the Properties UI render correctly?
Its a little random-ish but a way to make sure the render bug shows its head is;
- select a message
- click on another view so it loses focus
- click on a new message in the Messages View, the Properties View should look a bit borked
- click on the original message in the Messages View it should now render fine again
