correct use of choice

Hi,

I want to test out filters. I have this route:

<route id="route1">

   <from uri="direct:start" />						
   <to uri="bean:compAImpl" />

   <camel:setHeader
headerName="goto"><camel:constant>B</camel:constant></camel:setHeader>

   <camel:choice>

      <when>
           <camel:simple>in.header.goto='B'</camel:simple>
           <to uri="bean:compBImpl" />
      </when>

      <otherwise>
           <to uri="bean:compCImpl" />
      </otherwise>

   </camel:choice>
</route>

It is not working. only C is invoked.

What is wrong?

The simple languages support a limited set of operators as listed here
http://camel.apache.org/simple.html

The eq is using double = so you should use == instead of only a single =

And you need ${ } around the header. Just check the simple
documentation page as there are plenty of examples.
