you will need to use the ContributorManager object on the repository connection to be able to get the details from the contributor objects in the list

Hi Sam thanks for quick reply.
I am writing custom advisor. I have tried with IworkItemServer method. I am getting attribute first(Using IworkItemServer.findAtribute () method). When I used workitem.getValue(custom_Contributor_attribute_filed) it is giving me  IContributorHandle of default user(i.e Unassigned) even though I have selected particular user(This field is like "Owned by" field). I am not able to get currently selected user in the custom_Contributor_attribute_filed. I tried with IworkItemServer enumeration mehtod but getting assertionFailed error(Also tried with EnumerationManager.internalresolve(...) method). Please let me know if anyone have idea to how to get value custom attribute of type contributor?

Funny, I just realized I have no example for the server, where I resolve the contributor handle to a contributor. Hang in there, I am trying to create one.

Nilesh, you can find example code here: http://rsjazz.wordpress.com/2012/11/30/a-create-approval-work-item-save-participant/ there are other posts on that blog with examples you might be interested in.

Please be aware of http://rsjazz.wordpress.com/2012/12/14/do-not-modify-the-triggering-element-in-an-operationadvisor/ should you try to modify your work item in the advisor.

The code to get an arbitrary IContributor Handle resolved to an IContributor I found is: 

IContributorHandle creator = resolved.getOwner();
fRepositoryItemService=getService(IRepositoryItemService.class);


IContributor user = (IContributor) fRepositoryItemService.fetchItem(creator, IRepositoryItemService.COMPLETE);
You need to add the IRepositoryItemService to the prerequisites 

<prerequisites>
    <requiredservice interface="com.ibm.team.workitem.service.IWorkItemServer"/>
    <requiredservice interface="com.ibm.team.workitem.common.IWorkItemCommon"/>
    <requiredservice interface="com.ibm.team.repository.service.IRepositoryItemService"/>
</prerequisites>


This assumes you try to write an advisor for the server. On the client the API is different and you can find code in my blog for that. It also resolves the IContributorHandle.
