Balana and WSO2 Identity Server giving different results - wso2

Question

I have a policy and when i run a request in WSO2 Identity Server i get permit decision as expected. But when i create another sample policy from:
http://svn.wso2.org/repos/wso2/carbon/platform/tags/4.0.7/products/is/4.1.0/modules/distribution/conf/policies/sample-kmarket-sliver-policy.xml
And send my same request again, i get following error:
<Response xmlns="urn:oasis:names:tc:xacml:3.0:core:schema:wd-17">
<Result>
<Decision>Indeterminate</Decision>
<Status>
<StatusCode Value="urn:oasis:names:tc:xacml:1.0:status:missing-attribute"/>
<StatusMessage>Couldn't find AttributeDesignator attribute</StatusMessage>
<StatusDetail>
<MissingAttributeDetail AttributeId="http://kmarket.com/id/role" DataType="http://www.w3.org/2001/XMLSchema#string" Category="urn:oasis:names:tc:xacml:1.0:subject-category:access-subject" ></MissingAttributeDetail>
</StatusDetail>
</Status>
</Result>
</Response>
For some reason request is being run against this sample policy instead of my original policy. Now interesting thing is I downloaded Balana (XACML Engine used by WSO2 Identity Server) source code and ran tests with both policies and my request and i am getting Permit as expected. But when i do the same in WSO2 its not working and i am getting Indeterminate error. I tried both 'Try It' feature and 'Evaluate with PDP' with same results.
Here is the request i used, why is this being applied to the sample policy and not my original policy via WSO2 but not Balana?

According to the error, it seems that attribute finder is not configure. I guess policy has a attribute id called "http://kmarket.com/id/role" But it is not in the request, so attribute finder is called. you need to register an attribute finder to support it... Please find sample attribute finder from here [1]. In balana sample, this attribute finder has been already there with the sample itself
