Getting an IAttribute object from an attribute id on a server extension


Philipp H (53113) | asked Aug 18 '16, 5:05 a.m.
 Hi everyone,

I want to use getValue on a WorkItem in my Server Extension, but for that I need an IAttribute object.
I have the attribute id.
How do I get the IAttribute object?

Thanks

For reference I tried:
this, this and some bits of this which gave me the error:
failed to find the required service 'interface com.ibm.team.workitem.common.IWorkItemCommon'
even tho I have IWorkItemCommon in my prerequisites.

You probably need to use IWorkItemServer (which extend IWorkItemCommon) as prerequisite and in the getService method. Then you can also use it for the rest of the operation or cast it to IWorkItemCommon.

https://rsjazz.wordpress.com/2012/07/31/rtc-update-parent-duration-estimation-and-effort-participant/ shows how this is done in a participant/follow up action and the same mechanism applies in advisors/precondition. It is basically the same mechanism explained in https://jazz.net/forum/questions/226930/how-to-get-icontributor-objects-from-a-workitem where you don't specify the context.

You should use IWorkItemCommon wherever you can and it is possible to use it here. I don't know why you can't get it. I agree with Michele on the alternative and the example above uses IWorkItemServer an works.

Well, if you change a something in the plugin.xml (like the prerequisites) you always have to recompile and restart the server, also when you are on debug mode.
