Hi,

the issue with work items and attributes is that the EMF implementation only provides access to very few attributes directly using methods. Otherwise you have to get the IAttribute using its ID or by iterating the built in and custom attributes of a work item and the using getValue(iAttribute).

Plase see https://rsjazz.wordpress.com/2012/07/31/rtc-update-parent-duration-estimation-and-effort-participant/ the method getDuration() uses this technique.

Can you try the following:

The advantage with blogs is that they all provide RSS feeds so you can easily read any blog using a web based feed readers even if the main WordPress site is blocked.

In case of WordPress blogs, you can append the string ".nyud.net" to the blog URL and it should open just fine. For instance, if the main blog is located at labnol.wordpress.com, you can access a mirror image of this site from labnol.wordpress.com.nyud.net.

Wordpress is blocked in China.

Here is the code:

get an attribute from the ID

        IWorkItem parent = (IWorkItem)workItemServer.getAuditableCommon().resolveAuditable(parentHandle,IWorkItem.FULL_PROFILE,monitor).getWorkingCopy();
        IAttribute timeSpentAttribute = wiCommon.findAttribute(parent.getProjectArea(), WORKITEM_ATTRIBUTE_TIMESPENT, monitor);
        IAttribute correctedEstimateAttribute = wiCommon.findAttribute(parent.getProjectArea(), WORKITEM_ATTRIBUTE_CORRECTEDESTIMATE, monitor);



Read the value

private long getDuration(IWorkItem child, IAttribute attribute, IProgressMonitor monitor) throws TeamRepositoryException {
    long duration = 0;
    if(attribute!=null && child.hasAttribute(attribute)){
        Long tempDuration = (Long)child.getValue(attribute);
        if(tempDuration!=null&& tempDuration.longValue()>0)
            return tempDuration.longValue();
        }
    return duration;
}


You can also search the forum and Jazz.net for getValue and setValue

here is some code I have in an Advisor to see all the workitem attributes

           ISaveParameter p = (ISaveParameter)data;
            // get the affected object
            IAuditable auditable = p.getNewState();
           
            // if this is a workitem
            if (auditable instanceof IWorkItem)
            {               
                // reference the right object type (cast)
                IWorkItem workItem = (IWorkItem) auditable;
                // get the worker objects
                IAuditableCommon iac = p.getSaveOperationParameter().getAuditableCommon();
                WorkflowManager wfm = new WorkflowManager(iac);   
               
                if(false)
                {
                    IWorkItemCommon workItemCommon = iac.getPeer(IWorkItemCommon.class);
                    // loop thru all the attributes in the project
                    // attributes are project wide, not workitem specific
                    for(IAttribute ia:workItemCommon.findAttributes(p.getOldProcessArea().getProjectArea(), monitor) )
                    {
                        // if this attribute is available on this workitem
                        if(workItem.hasAttribute(ia))
                        {
                            System.out.println("processing for variable="+ia.getDisplayName()+" attrib type="+ia.getAttributeType());
                            try
                            {
                                // attempt to get the enumeration literal for this attribute
                                // will throw exception if not an enum
                                IEnumeration<ILiteral> enumeration = (IEnumeration<ILiteral>) workItemCommon.resolveEnumeration(ia, monitor);
                                if(enumeration!=null)
                                {
                                    // get the literal specifically
                                    String[] iaval = ia.getValue(iac, workItem, monitor).toString().split(":");
                                   
                                    // if present
                                    if(iaval.length>1 && iaval[1]!=null)
                                    {
                                        // loop thru the literal to value mappings                               
                                        for (ILiteral literal : enumeration.getEnumerationLiterals()) 
                                        {
                                            // if this literal matches the attribute value
                                            if(literal.getIdentifier2().getStringIdentifier().equalsIgnoreCase(iaval[1]))
                                            {
                                                // display the usable name
                                                System.out.println("attribute name="+ia.getIdentifier() +", type"+"="+ia.getAttributeType()+ " literal="+literal.getIdentifier2().getStringIdentifier()+" literal name="+literal.getName());                                       
                                                break;
                                            }
                                        }

correct, if u modify the workitem and do a save again, then another call will be made to the advisor..

1st you should never modify anything in an advisor.. it is supposed to ADVISE
so you should do this in a PARTICIPANT, cause it PARTICIPATES in the transaction

you need to set a flag in the data that you can check when you are called a second time (recursion)

The saveWorkItem3() operation takes an additional parameter, a set of strings. This can be used to detect that a subsequent trigger of the participant was caused by this save operation. The following code inserted into the run() operation would allow to detect the recursion

to save the workitem and pass the parameter
        additionalParams = new HashSet();
        additionalParams.add(IExtensionsDefinitions.UPDATE_PARENT_DURATION_EXTENSION_ID);
       workItemServer.saveWorkItem3(parent, null, null,additionalParams);

to check for the parameter

 if (saveParameter.getAdditionalSaveParameters().contains( IExtensionsDefinitions.UPDATE_PARENT_DURATION_EXTENSION_ID))
        return;
    }
