@pasqualre congiusti: I came across this discussion thread and wanted to
confirm if it's still possible to achieve this.
@claus: Thanks for the reply. I tried that approach, but it didn't work for
me. I am on Camel 4.4.0. I get an error saying the Kamelot is not found,
but I am able to invoke the kamelet individually from the route.yaml. If I
add the call of the second kamelet inside the first Kamelet, I get the
error below. any pointers would be appreciated.
snippet of route.yaml
---
- kamelet: nonstop-logtwo?response_class_name=second
- kamelet: nonstop-log?response_class_name=first
---
snippet of 1st kamelet:
---
- to: kamelet:nonstop-logtwo?response_class_name=abas
---
