Camel editor is blank if a root element is <route>

It seems that the camel editor needs <routes> a the root element. If the route looks like

<?xml version="1.0" encoding="ASCII"?>
<route xmlns="http://camel.apache.org/schema/spring">
<from uri="switchyard://SimpleService"/>
<log message="SimpleService - message received"/>
<bean ref="MyAction" method="displayMessage"/>
<log message="SimpleService - playing with message content"/>
<bean ref="MyAction" method="playWithMessage"/>
<bean ref="MyAction" method="displayMessage"/>
<to uri="switchyard://PrintService"/>
</route>

then the editor is blank.
