CatchDefinition cannot be cast to ChoiceDefinition cTry/cMessageRouter

Anonymous — Sat, 16 Nov 2024 11:30:18 GMT

Hi,
I have a route where I want to execute a job and fallback to a second job if the first one fails. If both fail a custom error message should be returned to the client. If the client request doesn't fulfill certain conditions, an error message will be returned without trying.

I get a ClassCastException:

org.apache.camel.model.CatchDefinition cannot be cast to org.apache.camel.model.ChoiceDefinition
java.lang.ClassCastException: org.apache.camel.model.CatchDefinition cannot be cast to org.apache.camel.model.ChoiceDefinition

Activating "Append endChoice()" on the when condition doesn't help. Should I open a JIRA issue for it? What's the recommend workaround in this case?
I'm using TOS 5.5.1.
Cheers
Dennis

This Camel FAQ entry is helpful: https://camel.apache.org/why-can-i-not-use-when-or-otherwise-in-a-java-camel-route.html
Of course it works if I split up the route in multiple routes but in my view the TOS should not produce invalid code.
