Bartosz Popiela updated CAMEL-19343:
------------------------------------
Description:
Templated routes with the "choice" processor share the same Predicate
({_}org.apache.camel.model.WhenDefinition#expression#predicate{_}) and because
it is initialized with template parameters of the first route created, it fails
for the other routes. This is particularly visible when using Kamelets.
The proposed solution would be for _org.apache.camel.model.WhenDefinition_ to
accept Supplier<Predicate> (or similar) instead of the Predicate instance but
that would require static factory methods in
_org.apache.camel.support.builder.PredicateBuilder_ to be refactored or a new
class to be created.
[This|https://github.com/bartoszpop/CAMEL-19343/blob/main/src/test/java/io/github/bartoszpop/camel/Camel19343Test.java]
is the unit test. It fails for the second instance of the template.
