> I like to use steps in my routeTemplates. This works, however when I want to
> specify the ID I cannot use template parameter:
> {code:java}
> <routeTemplates id="camel" xmlns="http://camel.apache.org/schema/spring";>
> <!-- create a route template with the given name -->
> <routeTemplate id="myTemplate">
> <!-- here we define the required input parameters (can have default
> values) -->
> <templateParameter name="name"/>
> <templateParameter name="greeting"/>
> <templateParameter name="myPeriod" defaultValue="3s"/>
> <route>
> <from uri="timer:{{name}}?period={{myPeriod}}"/>
> <step id="{{name}}">
> <setBody>
> <simple>{{greeting}} {{name}}</simple>
> </setBody>
> <log message="${body}"/>
> </step>
> </route>
> </routeTemplate>
> </routeTemplates> {code}
> When I create 2 routes with the above template I get the following error:
> {code:java}

> The step ID doesn't get interpolated and is used a the literal "\{{name}}". I
> need to set the step id myself to get information about the specific route.
> Note that I run into when I was using kamelets with the step EIP, but this is
> a smaller example.
