Grails Camel Routing Plugin Not recognising sendMessage - grails

Question

We have a project that we recently required the use of Camel in. This projects is a Groovy/Grails project and I have installed the Routing 1.4.1 plugin.
I then proceeded to create a new route as specified in the documentation which is shown below:
package some_package
import org.apache.camel.builder.RouteBuilder
class TestRoute extends RouteBuilder {
def grailsApplication
#Override
void configure() {
def config = grailsApplication?.config
// example:
from('seda:input.queue').to('stream:out')
}
}
Then I proceeded to setup a call to this Route in one of my Controllers using the following 'sendMessage' command:
//Camel Testing
def message = "This is some history"
sendMessage("seda:input.queue", message)
However when typing in the IDE the 'sendMessage' method it does say 'Type Not Found' which says to me maybe I am missing an import of something but according to the documentation this should be available to all Controllers and Services.
I added debug and the code hits the sendMessage line however does not get into the routing method.
Can someone please help with this?
Thanks
************UPDATE***********
So I installed everything again from scratch and used an older version of InteliJ and the simple example worked great.
Next I tried a more complex example of calling a service, however the app fails on startup, I have put the Service, Route and sendMessage data below:
Route
from("seda:input.queue").filter {
it.in.body.contains("test")
}.to("bean:TestService?method=printMsg")
Service
def printMsg(msg){
println(msg)
}
sendMessage
def myMessage = "this is a test message"
sendMessage("seda:input.queue", myMessage)
The error I get when running the app is below:
Error 2015-08-07 13:46:46,156 [localhost-startStop-1] ERROR context.GrailsContextLoaderListener - Error initializing the application: groovy.lang.MissingMethodException: No signature of method: org.grails.plugins.routing.processor.PredicateProcessor.to() is applicable for argument types: (java.lang.String) values: [bean:TestService?method=printMsg]
Possible solutions: is(java.lang.Object), any(), use([Ljava.lang.Object;), getAt(java.lang.String), with(groovy.lang.Closure), any(groovy.lang.Closure)

I hope you can help.
Update
Ok so i removed the filter piece and the application loaded.
However when the sendMessage got run I got the following error:
Message: No bean could be found in the registry for: TestService
I then tried to add the bean manually using the following code but still get the same error:
void configure() {
def config = grailsApplication?.config
SimpleRegistry registry = new SimpleRegistry();
registry.put("TestService", new TestService());
CamelContext context = new DefaultCamelContext(registry);
from("seda:input.queue").to("bean:TestService?method=printMsg")
}

Answer 1

What you need to do is use ProducerTemplate class as follows:
CamelContext context //the Camel Context running your routes
ProducerTemplate template = context.createProducerTemplate()
Object resultBody = template.sendBody("seda:input.queue", "Your body")
println(resultBody) //anything that your route puts in the body

Answer 2

I have managed to fix this and it was down to a missname of the bean.
I found the error by listing all current beans in the context and then changing my call.
