Claus Ibsen commented on CAMEL-5156:
------------------------------------
What do you do in your processor: NullRegistrationDateProcessor
> simple language is not working in onException policy (for example retryWhile
> clause).

> Key: CAMEL-5156
> URL: https://issues.apache.org/jira/browse/CAMEL-5156
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.9.1
> Reporter: Radoslaw Szymanek
> Assignee: Claus Ibsen
>
> The bug was checked against 2.9.1 version of Camel.
> The simple language expressions are not calculated properly within
> onException clause.
> The route below only works as expected because I copy the the exchange and
> remove information about the exception. If the original exchange with
> exception information is used with simple language then the exception will be
> rethrown during (at the end?) the calculation of simple expression.
> If I copy the exchange and remove the exception information then the unit
> tests are passing nicely and the file with proper content is created, so
> simple language expression can be calculated properly for the object being
> routed.
> {code}
> from("direct:toPropertyFileAvoidFixingUnfixable")
> .onException(NullPointerException.class)
> .onRedelivery(new NullRegistrationDateProcessor())
> .handled(true)
> .retryWhile(new Predicate() {
> public boolean matches(Exchange exchange) {
> Predicate composite =
> PredicateBuilder.and(PredicateBuilder.isNull(simple("${body?.getRegistrationDate}")),
>
> PredicateBuilder.isNotNull(simple("${body?.getBirthdate}")));
> // Exchange with exception will make computation of
> simple predicate fail.
> Exchange local = exchange.copy();
> local.setException(null);
> boolean result = composite.matches(local);
> return result;
> }
> })
> .end()
> .setHeader(Exchange.FILE_NAME,
> simple("${body.firstname}.${body.surname}"))
> .bean(RegistrationToPropertiesBean.class, "convert")
> .to("file://" + outFolder);
> {code}
> It is related to the issue https://issues.apache.org/jira/browse/CAMEL-4513.
> My guess is that the problem is present for many other places where simple
> language can be used within onException part of the route definition. Not
> just retryWhile and custom predicate used within retryWhile.
