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: 1.5.0, 1.4.0
Reporter: Balázs Zsoldos
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.
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.
