camel Java DSL Choice in a Choice

Question

I want to have

_ from( A )
_ .split()...
_ .choice() //Choice 1 
_   .when( predicate )
_     .process()

_     .choice() // Choice 2 
_       .when( x )
_         .to( X )
_       .otherwise()
_         .to( Y )
_     .end() // to terminate inner choice

_   .endchoice() // tell camel we're back in the outer-choice - gets exception
_   .otherwise() // Choice 1
_     .to( Z )
_ .end()

but I get runtime exception on the endChoice()

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

I get compile time error without it

I suspect end() is ending the inner and outer choice, I only want it to end the inner one.

not putting in the end() makes it treat the second otherwise() as an extension of the inner-choice. Which it isn't.

I have found workaround by putting the second choice in a sub-route and "direct:SUB_ROUTE"-ing into it, but I would prefer to use the plainer structure I've outlined above if I could. Is there a way to achieve Choices in Choices or is this just a limitation of the Java DSL?

Are you sure about that? Infact, I think removing the end() from there should resolve your problem. The endchoice() is enough to indicate the end of the inner choice construct.

I did try a sample code with it and it was working fine..

Thanks!
