-----------------------------------------------
> Provide error at build time or runtime when a `method` attribute is used
> inside a when clause in xml dsl
> --------------------------------------------------------------------------------------------------------
>
> Key: CAMEL-22884
> URL: https://issues.apache.org/jira/browse/CAMEL-22884
> Project: Camel
> Issue Type: Improvement
> Affects Versions: 4.17.0
> Reporter: Aurélien Pupier
> Assignee: Guillaume Nodet
> Priority: Minor
>
> Currently, when a method attribute is provided at the wrong place, it is
> still called and can be a duplicate of when expression clause.
> It must be at the first position. And there shouldn't be several clause
> expression for the when.
> For instance:
> {noformat}
> <routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
> xmlns="http://camel.apache.org/schema/spring";
> xsi:schemaLocation="
> http://camel.apache.org/schema/spring
> http://camel.apache.org/schema/spring/camel-spring.xsd";>
> <route xmlns="http://camel.apache.org/schema/spring";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
> <from uri="direct://start"/>
> <choice>
> <when>
> <xpath saxon="true">/*:test/*:foo/text() = 'bar'</xpath>
> <log message="Condition met: foo equals bar"/>
> <method ref="someBean" method="processFooBar"/>
> </when>
> <otherwise>
> <log message="Condition not met: foo does not equal bar"/>
> </otherwise>
> </choice>
> </route>
> </routes>
> {noformat}
> the route will star without any issue and the second method will be called.
> The xsd validation is rejecting it but if no xsd validation used, the route
> is accepted at build time and runtime.
> it would nice to fail the build when it happens.
