[jira] [Commented] (SYNAPSE-890) Pattern attribute of the property
mediator does not seem to work
[ https://issues.apache.org/jira/browse/SYNAPSE-890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13412615#comment-13412615 ]

---------------------------------------------------
Hi
Ideally I think when the given pattern is not matched at the property mediator it should return a empty string, the fix patch is attached herewith
cheers

> Key: SYNAPSE-890
> URL: https://issues.apache.org/jira/browse/SYNAPSE-890
> Project: Synapse
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.1
> Environment: Ubuntu 12.04
> Reporter: Dushan Sachinda Abeyruwan
> Priority: Critical
> Fix For: FUTURE
>
> Attachments: PropertyMediator.java.patch
>
>
> Steps to reproduce:
> ================
> 1. Create a sequence like the following
> <sequence xmlns="http://ws.apache.org/ns/synapse" name="main">
> <in>
> <switch xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns3="http://org.apache.synapse/xsd" xmlns:m0="http://services.samples" source="//m0:getQuote/m0:request/m0:symbol">
> <case regex="IBM">
> <property name="symbol" value="Great stock - IBM" />
> </case>
> <case regex="MSFT">
> <property name="symbol" value="Are you sure? - MSFT" />
> </case>
> <default>
> <property name="symbol" expression="fn11:concat('Normal Stock - ', //m0:getQuote/m0:request/m0:symbol)" scope="default" />
> </default>
> </switch>
> <property xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns3="http://org.apache.synapse/xsd" xmlns:m0="http://services.samples" name="MyProp" expression="//m0:getQuote/m0:request/m0:symbol" pattern="[a-zA-Z_0-9]" scope="default" />
> <log level="custom">
> <property xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns3="http://org.apache.synapse/xsd" name="symbol" expression="get-property('symbol')" />
> <property xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns3="http://org.apache.synapse/xsd" name="epr" expression="get-property('To')" />
> <property xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns3="http://org.apache.synapse/xsd" name="customProperty" expression="get-property('MyProp')" />
> </log>
> <send />
> </in>
> <out>
> <send />
> </out>
> </sequence>
> 2. Note the following property mediator in the above sequence. I used pattern attribute in there to evaluate the result of xpath expression against a regex
> <property xmlns:ns="http://org.apache.synapse/xsd" xmlns:ns3="http://org.apache.synapse/xsd" xmlns:m0="http://services.samples" name="MyProp" expression="//m0:getQuote/m0:request/m0:symbol" pattern="[a-zA-Z_0-9]" scope="default" />
> According to the above regex, I should only set the property value if the Xpath expression result is alpha-numeric
> 3. Send a request with the following payload (note the non-alpha numeric character)
> <m0:getQuote xmlns:m0="http://services.samples">
> <m0:request>
> <m0:symbol>%</m0:symbol>
> </m0:request>
> </m0:getQuote>
> 4. Check the log mediator output (value of the customProperty)
> INFO - LogMediator symbol = Normal Stock - %, epr = http://localhost:9000/services/SimpleStockQuoteService, customProperty = %
