[jira] Created: (CAMEL-1261) camel-spring - method call language can not be used with split

camel-spring - method call language can not be used with split
--------------------------------------------------------------

                 Key: CAMEL-1261
                 URL: https://issues.apache.org/activemq/browse/CAMEL-1261
             Project: Apache Camel
          Issue Type: Bug
          Components: camel-core, camel-spring
    Affects Versions: 1.5.0
            Reporter: Claus Ibsen
            Assignee: Claus Ibsen
             Fix For: 1.5.1, 2.0.0


Using a method call for the split expression is not possible in Spring DSL. It wants to resolve the language.

As we dont have all the expression builder helper in Spring XML its a bit harder to do routing. But I want to use a bean for the splitting. End users should always have the true power of java, regardless.
{code}
            <split>
                <expression>
                    <method bean="echoService" method="splitWords"/>
                </expression>
                <to uri="bean:echoService?method=hello"/>
                <to uri="stream:out"/>
            </split>

{code}

And gives this exception:

{code}

---------------------------------------

kinda conflused by this - as SplitterType is an ExpressionNode (just like filter, when) so it should allow expressions as children?

{code>
<split>
 <method bean="echoService" method="splitWords"/>
</split>
{code}

this works for me in IntelliJ. Indeed there's a test case splitterWithCustomThreadPoolExecutor.xml in camel-spring

Okay I got confused. The <expression> should not be there. Its a shallow that we should try to get out of the XSD

Claus Ibsen commented on CAMEL-1261:
------------------------------------

I suggest to rename expression to languageExpression or kinda remove it all together. Its used for expression using language where you set the language name in an attribute. Hardly used in Spring DSL where we have XSD types for all the languages (xpath, groovy, el, methodCall, etc.)

I still think it should be removed as its a xs:any type and its confusing what it can be used for.

Claus Ibsen resolved CAMEL-1261.
--------------------------------

       Resolution: Duplicate
    Fix Version/s:     (was: 1.5.1)

False alarm. Have created a new ticket with the rename of the expression to language. And avoiding it being a tns:any type.
