RTC API Exception : Attempting to get unset feature: Category though the value in the workitem is set.

Jazzuser user (68●10●50) | asked Nov 03 '17, 7:40 a.m.

Hello All,

I need to fetch the Task workitem's Category(Filed Against) value. I am using the following code :

    com.ibm.team.workitem.common.model.IAttribute attributename=rtcDataAccessProvider.getWorkItemClient((ITeamRepository)currentWorkItem.getOrigin()).findAttribute(currentWorkItem.getProjectArea(), IWorkItem.CATEGORY_PROPERTY, monitor);
        if(currentWorkItem.hasAttribute(attributename )){
            Object  value =currentWorkItem.getValue(attributename);
  }

Am getting the following exception, though the category value is set for the Task.

Exception in thread "main" java.lang.IllegalStateException: Attempting to get unset feature: Category
    at com.ibm.team.workitem.common.internal.model.impl.WorkItemImpl.getCategory(WorkItemImpl.java:1672)
    at com.ibm.team.workitem.common.internal.model.impl.WorkItemImpl.eGet(WorkItemImpl.java:2352)
    at org.eclipse.emf.ecore.impl.BasicEObjectImpl.eGet(BasicEObjectImpl.java:1021)

However same code is working fine for other workitems. Is there any other way for accessing the Task's attribute ?

Please assist.

I have explained what I know here: https://rsjazz.wordpress.com/2013/01/02/working-with-work-item-attributes/
I can't identify what rtcDataAccessProvider is. Nor is it clear where in the statement the error actually happens.
attributename is a bad name for the IAttribute, because you use the name to get the IAttribute.

Otherwise it is almost impossible to remote debug this kind of stuff.
