[jira] Commented: (SYNAPSE-503) get-property function is not
recognized in xquery variable expression attribute
[ https://issues.apache.org/jira/browse/SYNAPSE-503?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12673469#action_12673469 ]
Asankha C. Perera commented on SYNAPSE-503:
-------------------------------------------
There is no implementation of a get-property('body')
Did you look at Sample#390? That should show you how to achieve what you need

> Key: SYNAPSE-503
> URL: https://issues.apache.org/jira/browse/SYNAPSE-503
> Project: Synapse
> Issue Type: Bug
> Components: Extension Mediators
> Affects Versions: 1.3
> Reporter: Michal Stochmialek
> Fix For: 1.3
>
>
> I'm transforming response of the remote service in outSequence of a proxy.
> I'm using xquery mediator. I want to change the format of the payload of the response
> and also I want to insert a payload of the request into a first element of the response.
> 1. proxy: gets request A,
> 2. inSequence: transforms request A to request B,
> 3. endpoint: sends request B to remote service,
> 4. endpoint: receives response B,
> 5. outSequence: transforms response B to response A with request A included.
> To do that, I'm storing the request A payload in a variable and in outSequence
> I'm want to use it in XQUERY mediator while transforming the response.
> Here's a fragment of the synapse.xml:
> <xquery key="response.xq" trace="enable">
> <variable name="payload" type="ELEMENT"/>
> <variable name="request" expression="synapse:get-property('body')" type="ELEMENT"/>
> </xquery>
> On the runtime I've got following exception:

> Unable to execute the query
> After looking a bit at XQueryMediator code it seems it uses AXIOMXPath class instead of SynapseXPath class.
> This seems to be a reason of the exception.
