This is probably caused by the Event Handler Service that's not working/installed on my machine. How can I find out what's wrong with the Event Handler Service? Where to look for the web service?    Report

The default location of the web service is: http://[TFSHost]/ScrumforTeamSystem/WorkItemChangedEvent.asmx It is possible to enable trace file logging on the service by specifing an output file within the web.config. I've explained how to accomplish this in this forum thread: http://scrumforteamsystem.com/cs/forums/1567/ShowPost.aspx#1567 Hope this helps. Regards, Crispin Parker, Technical Consultant, Conchango.

I managed already to activate the logging. The field is not recalculated after changes to a SBI, but when I manually call the webservice, the field gets updated! So my question now : why isn't this working automatically after changes to the SBIs?    Report

Is there any messages in the Event log [on the TFS machine] that indicate a problem? Crispin. "It is better to light a candle than to curse the darkness"    Report

To do this, open a SQL Management Studio instance on the TFS machine and then execute the below script: SELECT [id]       ,[event_type]       ,[expression]       ,[subscriber]       ,[schedule]       ,[delivery_type]       ,[address]       ,[classification]   FROM [TfsIntegration].[dbo].[tbl_subscription] If the server is correctly set up, there should be an entry that specifies the"WorkItemChangedEvent" and points to the scrum service endpoint. If this entry does not exist, then you will need to re-install the SfTS template. Another thing to check is that the "Visual Studio Team Foundation Server Task Scheduler" service is running. This service is required in order to broadcasting the work item changed events. Crispin. "It is better to light a candle than to curse the darkness"    Report

I installed the ScrumForTeamSystem webservice on the TFS website on port 8080, but the address in the tbl_subscription table pointed to the default port 80. After setting the port correctly in the address field everything worked. Problem solved. Thx for pointing me in the right direction!    Report

The "WorkItemChanged" event is triggered whenever a work item is saved to the tfsWorkItem database regardless of source project. If one of the projects is getting updated and the others are not, then the issue is not with subscriptions. I suggest that you enable logging in the event handling service and see if that revels any clues to the cause of the problem. The following post details how to enable event logging. http://scrumforteamsystem.com/cs/forums/2048/ShowPost.aspx#2048 You will need to restart IIS in order for the TFS process to pick up changes to the Subscription table. Hope this helps, post back if you need to. Regards, Crispin Parker, Technical Consultant, Conchango. "It is better to light a candle than to curse the darkness"    Report

10-08-2008, 12:35 AM buildboy Joined on 03-03-2008 Posts 2 Re: Event Handler Service - update "Work Remaining (hours)" in Product Backlog item That makes sense except for the filter that is part of the Subscription. The filter expression look like this: "PortfolioProject" = '<project name>' AND ("CoreFields/StringFields/Field[ReferenceName = 'System.WorkItemType']/NewValue" = "Sprint Backlog Item") OR ("CoreFields/StringFields/Field[ReferenceName = 'System.WorkItemType']/NewValue" = "Product Backlog Item") OR ("CoreFields/StringFields/Field[ReferenceName = 'System.WorkItemType']/NewValue" = "Bug") Is this wrong?  I thought that this subscription & filter was created by the Scrum plug-in.  We had another subscription that did not contain a filter and we needed to remove because it kept throwing a null exception.  We found that one the fields it was expecting had been removed from the work item from. Thank you    BuildBoy      Report
