Claus Ibsen resolved CAMEL-4090.
--------------------------------
Resolution: Fixed
> Add support for setting resultType on Simple expressions
> --------------------------------------------------------
>
> Key: CAMEL-4090
> URL: https://issues.apache.org/jira/browse/CAMEL-4090
> Project: Camel
> Issue Type: New Feature
> Components: camel-core
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Fix For: 2.8.0
>
>
> When people are using the simple expression such as setting a header etc,
> they may want to control what the result type of the expression is. Suppose
> they want to set a boolean
> {code:xml}
> <setHeader headerName="foo">
> <simple>true</simple>
> </setHeader>
> {code}
> What happens is that the type of the foo header will be a String as thats the
> default type from a simple expression.
> We should add the resultType attribute which other expressions has such as
> XPath/XQuery etc.
> Then you can do as follows:
> {code:xml}
> <setHeader headerName="foo">
> <simple resultType="java.lang.Boolean">true</simple>
> </setHeader>
> {code}
> Likewise it should be possible in Java DSL.
