----------------------------------
Attachment: (was: XQueryBuilder.java.patch)
> XQuery creates an empty out message that makes it impossible to chain more
> processors behind it
> -----------------------------------------------------------------------------------------------
>
> Key: CAMEL-1057
> URL: https://issues.apache.org/activemq/browse/CAMEL-1057
> Project: Apache Camel
> Issue Type: Bug
> Components: camel-saxon
> Affects Versions: 1.4.0, 1.5.0
> Reporter: Balázs Zsoldos
> Priority: Critical
> Fix For: 1.5.1
>
> Attachments: XQueryBuilder.java.patch
>
>
> When using XQuery the getOut() function is called on the message so if it is
> not used at a place where the out is filled an empty out message will be
> created. With this xquery cannot be used for example in setBody, setHeader...
> and anywhere where the out is not filled.
> An example where this causes real trouble:
> <choice>
> <when>
> <xquery>...</xquery>
> <to uri="direct:follow" />
> </when>
> </choice>
> ...
> <from uri="direct:follow">
> <to ...>
> <to ...>
> In the patch the out property in the xquery context is filled only if it is
> not null. With it all of my pipelines seem to work well for me.
