What version of Camel are you using?
I tried that with the latest fuseesb (7.0.0.fuse-061) which contains camel 2.9.0.fuse-7-061
There message tracing in Fuse IDE (eg from the right click menu) is only available on Fuse ESB / Fuse Camel as its an enhancement over vanilla Apache Camel.
In vanilla Apache Camel there is also a tracer, but its a poor mans tracer, that logs to the log file. So just mind that there is 2 different things.
I suggest to upgrade Fuse IDE if its possible as we have constantly improved and fixed bugs in it since the 7.0.0 release.
