How to get value of a customeattribute use plain java api
Hi all:
I am trying to develop RTC extensions these days, I got a instance from the https://jazz.net/library/article/1000, that is a example of RTC extension developement with a very long documentation, I have done the whole example, but now I want to make a little modification to do something else, for example, put a custome attribute value to another attribute, I attempt to edit the run mothod of class BuildOnStateChangeParticipant, below is a piece of run method of this class:
public void run(AdvisableOperation operation,
IProcessConfigurationElement participantConfig,
IParticipantInfoCollector collector, IProgressMonitor monitor)
throws TeamRepositoryException {
/*
* There are several reasons not to request a build. This code is
* structured to perform the most common and fastest cases first. The
* idea is to find out as quickly as possible that you have nothing to
* do. Depending on how the participant is configured (which process
* area(s), iteration(s) or roles it affects), it could be called for
* all work item saves that occur in the using project area.
*/
/*
* First check that the operation data is work item save data.
*/
Object data = operation.getOperationData();
ISaveParameter saveParameter = null;
if (data instanceof ISaveParameter) {
saveParameter = (ISaveParameter) data;
/*
* If the state id has not changed, do not build.
*/
IWorkItem newState = (IWorkItem) saveParameter.getNewState();
Identifier<IState> newStateId = newState.getState2();
Identifier<IState> oldStateId = null;
IWorkItem oldState = (IWorkItem) saveParameter.getOldState();
I have already add a custome attribue named "test user" to the Story workitem type, and I want to copy its value to the "Owner" build-in attribue when the state changes, how can I do this?

HI, thanks for your reply, I also have the a) "teamRepository" b) IItemManager c) NullProgressMonitor unresolved problem, according to you answer, I found another guy's answer that refer to the same question, It use this code:
IAttributeHandle handle = ...
IRepositoryItemService itemService = getService(IRepositoryItemService.class);
IAttribute attribute = (IAttribute) itemService.fetchItem(handle, IRepositoryItemService.COMPLETE);
so I have a try, but it says "The service 'net.jazz.rtcext.workitem.extensions.service.BuildOnStateChangeParticipant@1d7c1d7c' failed to find the required service 'interface com.ibm.team.repository.service.IRepositoryItemService'. Check <prerequisites> in plugin.xml"
what is the matter?
and could you look into the code above, and give me some sample code that can fellow that
By the way I know there are client side api and server side api, what's different between them, and when I can use them?
I'm not certain what is causing the prerequisites error you're getting. My guess is that you need to add the repository as a required bundle.
The following code should be able to follow yours:
The following code should be able to follow yours:
System.out.println("The attribute id: " + attribute.getIdentifier());
System.out.println("The value of the custom attribute: " + workItem.getValue(attribute));
For your question about client side and server side api, refer to this forum post that has helpful links: https://jazz.net/forum/questions/10577/queries-regarding-clientside-and-serverside-api
