How can I get attachment file name of a work item in a customized attribute (calculated value or value set)? 
Do we have any way to do?

Background; A customer is using RELM to search RTC artifacts but attachment file name cannot be searched, so he is thinking to put the attachment filename in a customized attribute in a work item.

We are thinking to use HTTP Filtered Value Set Provider as one possible way, it is not successful to run yet.

 Hello,
I don't think this can be done: attachment(s) is not an attribute but a link.
You can use RTC Queries to search on attachments names, id:

 How to run a query in calculated value or value set?

the only approach that might work is described here: http://jorgediazblog.wordpress.com/2012/06/27/work-item-customization-httpconector-and-oauth-in-rtc-4-0-for-oslc/ You would have to use REST/OSLC to access the query.

Takki,

as far as I am aware you can't access the attachments collection from JavaScript in calculated value providers.

See: https://jazz.net/library/article/1093 Lab 5 especially the limitations.

You might be able to use tricks like the one provided by Jorge to succeed. Another way to proceed might be using Java as described here: https://rsjazz.wordpress.com/2013/06/26/attribute-customization-java-based-value-providers-conditions-and-validators/

JavaScript won't allow you to do this, I am sure.

In my testing, if I do the following, it works. 1. Customize attribute > Add Value set 'myValueSet’ / provider: HTTP Filtered Value Set Provider  >     Configuration: XML data source URL: https://<host>:9443/ccm/oslc/workitems/15/rtc_cm:com.ibm.team.workitem.linktype.attachment.attachment 　Row XPath : //Collection/Attachment Column XPath expression: ./title    Column Identifier : title    Authentication method: OAuth

 2. Create an attribute ’TestField1’ 3. Set the value set 'myValueSet’ in the attribute. 4. Add an editor presentation for the attribute with kind:picker.  But If I add an editor presentation for the attribute with kind:string, it won't work because it seems the return value is array.

Also it works by following: 1. Customize attribute > Add Value set 'myValueSet3’ / provider: Script based value set  > dojo.provide("com.example.ValueSetProvider3"); dojo.require("com.ibm.team.workitem.api.common.connectors.HttpConnectorParameters"); (function() {     dojo.declare("com.example.ValueSetProvider3", null, {         getValueSet: function(attributeId, workItem, context){

        var params= new com.ibm.team.workitem.api.common.connectors.HttpConnectorParameters();         params.url="https://vappwin2k8r2ja:9443/ccm/oslc/workitems/15/rtc_cm:com.ibm.team.workitem.linktype.attachment.attachment";         params.xpath= "//Collection/Attachment";         params.columnXpaths= ["./title"];         params.columnIds= ["title"];         params.ignoreInvalidCertificates=true;         params.useOAuth=true;         var connector= context.getDataConnector("HttpConnector");         var values= connector.get(params);         var result= [];

         while(values.hasNext()){              var entry= values.next();              var wiIDs= entry.getById("title");              result.push(wiIDs);          }          return result;      }     });  })();

But If I add an editor presentation for the attribute with kind:string instead, it won't work.

 hi 

this line of code

seems to be particular for a work item .
how to make it generic so that when we open a wok item its displays the attachment name attached to this work item.
