How to get ITeamRepository and IWorkItemClient (in RTC follow-up action)?

Hello everybody!
I'm trying to extend an RTC with follow-up action plug-in. It works well but untill I try to get workitem attributes. How to do it, I found a lot of excellent articles including this one:

http://rsjazz.wordpress.com/2013/01/02/working-with-work-item-attributes/

But I stumble at the step when I need get ITeamRepository and IWorkItemClient objects. For example, I used such code:

IProcessArea procarea = operation.getProcessArea();
ITeamRepository teamRepository1 = (ITeamRepository) procarea.getOrigin();
IWorkItemClient workItemClient1 = (IWorkItemClient) teamRepository1.getClientLibrary(IWorkItemClient.class);

and another one:

IProjectAreaHandle projhndl = newState.getProjectArea();
ITeamRepository teamRepository2 = (ITeamRepository) projhndl.getOrigin();
IWorkItemClient workItemClient2 = (IWorkItemClient) teamRepository2.getClientLibrary(IWorkItemClient.class);

But every time, I have null for the teamRepository object! Can somebody say what is wrong? As far as I understand, follow-up action is called by RTC under a user which is already connected to the repository. Can I get an existing reference to this data from within RTC extention plug-in?
Thank you very much in advance for any advices!

because your code is a subclass of abstractService you have access to methods to load libraries

from another plugin

fWorkItemServer = getService(IWorkItemServer.class);

fAuditableCommon = getService(IAuditableCommon.class);

fcontributorService = getService(IContributorService.class);

fProcessServerService = getService(IProcessServerService.class);

fQueryService = getService(IQueryService.class);

fItemService = getService(IRepositoryItemService.class);

note that you must declare the need to access these other services in your plugin.xml

<extensionService

componentId="com.sd.tools.workitem.createapproval.participant.component"

implementationClass="com.sd.tools.CreateApprovalParticipant">

</prerequisites>

</extensionService>

also all attributes, see here

Thank you very much!
Yes, I understand now the internal work of the solution. You really helped me to clarify this!

But is somebody else will be wondered the exact way which I used, I applied next code:

List<IAttributeHandle> wi_customs = wi.getCustomAttributes();
IRepositoryItemService itemService = getService(IRepositoryItemService.class);
for (int i = 0; i < wi_customs.size(); i++) {
IAttribute attribute = (IAttribute) itemService. fetchItem(wi_customs.get(i), IRepositoryItemService.COMPLETE);
<some operations with attribute>
}

And don't forget (as Sam pointed above) add next string manually into plugin.xml of service plugin project:

<requiredService interface="com.ibm.team.repository.service.IRepositoryItemService"/>

By the way, the solution is described here:

https://jazz.net/forum/questions/87341/how-to-fetch-the-workitem-built-in-custom-attribute-id-and-value

The conclusion - no need to apply ITeamRepository and IWorkItemClient here!

you are IN the repository..

most objects have a getOrigin() method which returns the repository..

see one of my plugins to do the rest .(or Ralph's blog) .post 2 has a working advisor to enforce depends/blocks

Sam,
Thank you for quick reply!

You write "most objects have a getOrigin() method which returns the repository". But I used getOrigin() for IProcessArea and IProjectAreaHandle objects which I found through class declarations. And everywhere getOrigin() returns null as if I'm out of the repository. This case strongly confuses me!

To make clear my end point, I need to get a list of all attributes for a workitem resulting from saving operation for this workitem. To get these attributes, I presume to use some code like next:

IWorkItemClient workItemClient = (IWorkItemClient) fTeamRepository.getClientLibrary(IWorkItemClient.class);
IAttribute someAttribute= workItemClient.findAttribute(fProjectArea, "some_attribute_ID", monitor);

But I can not get fTeamRepository which is always null!
