Issue regarding filter in wso2esb - wso2

Question

I'm using wso2dss3.1.0 and wso2esb 4.7.0.
I wish to filter the condition for that I have user filter mediator.
My proxy is like :
<filter xpath="get-property('mailid1')=''">
<then>
<log level="custom">
<property name="service called" value="then of inner filter"/>
<property name="mailid exist" value="creating new entry in muser with phonenumber as username"/>
</log>
<payloadFactory>
<format>
<p:Capp_insert_emercontactid xmlns:p="http://ws.wso2.org/dataservice">
<p:username>$1</p:username>
<p:firstname>$2</p:firstname>
<p:lastname>$3</p:lastname>
<p:phonenumber>$4</p:phonenumber>
<p:mailid>$5</p:mailid>
</p:Capp_insert_emercontactid>
</format>
<args>
<arg expression="get-property('phoneno1')" evaluator="xml"/>
<arg expression="get-property('firstname')" evaluator="xml"/>
<arg expression="get-property('lastname')" evaluator="xml"/>
<arg expression="get-property('phoneno1')" evaluator="xml"/>
<arg expression="get-property('mailid1')" evaluator="xml"/>
</args>
</payloadFactory>
<property name="HTTP_METHOD" value="POST" scope="axis2" type="STRING"/>
<property name="RESPONSE" value="true" scope="default" type="STRING"/>
<property name="NO_ENTITY_BODY" action="remove" scope="axis2"/>
<log level="full"/>
<send receive="UpdateEmergencyContact_seq3">
<endpoint>
<address uri="http://localhost:9764/services/Capp_MuserDataservice/" format="soap11"/>
</endpoint>
</send>
</then>
<else>
<log level="custom">
<property name="service called" value="else of inner filter"/>
<property name="Phonenumber exist" value="creating new entry in muser with mailid as username"/>
</log>
<payloadFactory>
<format>
<p:Capp_insert_emercontactid xmlns:p="http://ws.wso2.org/dataservice">
<p:username>$1</p:username>
<p:firstname>$2</p:firstname>
<p:lastname>$3</p:lastname>
<p:phonenumber>$4</p:phonenumber>
<p:mailid>$5</p:mailid>
</p:Capp_insert_emercontactid>
</format>
<args>
<arg expression="get-property('mailid1')" evaluator="xml"/>
<arg expression="get-property('firstname')" evaluator="xml"/>
<arg expression="get-property('lastname')" evaluator="xml"/>
<arg expression="get-property('phoneno1')" evaluator="xml"/>
<arg expression="get-property('mailid1')" evaluator="xml"/>
</args>
</payloadFactory>
<property name="HTTP_METHOD" value="POST" scope="axis2" type="STRING"/>
<property name="RESPONSE" value="true" scope="default" type="STRING"/>
<property name="NO_ENTITY_BODY" action="remove" scope="axis2"/>
<log level="full"/>
<send receive="UpdateEmergencyContact_seq3">
<endpoint>
<address uri="http://localhost:9764/services/Capp_MuserDataservice/" format="soap11"/>
</endpoint>
</send>
</else>
</filter>
I wish to do:
If mailid and phonenumber present in request then insert mailid as
username.
If only mailid present insert it as username.
if mailid absent insert phonenumber as username.
and configuration I have written is eorkinh fine for else part.
When mailid present proxy allow to insert it as username.
But problem occurred while mailid absent.In this case it sends blank username.. Even not accept hardcoded value.
Log for above at server side is like:
[2014-06-25 10:29:29,676] INFO - LogMediator phoneno1 = 111, mailid1 =
[2014-06-25 10:29:29,677] INFO - LogMediator service called = else of inner filter, Phonenumber exist = creating new entry in muser with mailid as username

Where is exact problem?
Am I missing something or doing some wrong while writing filter?
Please let me know soon.

Answer 1

it is simple error ..In your else condition . you are passing mail id as username..So, if mailid is not there, username also empty. Check your payload fcatory argument expression

Answer 2

in your filter xpath use boolean(get-property('mailid1')) and compare it with true and false.
