Hello  team

 I am using the below code to set the currentiteration for the timeine  :
 IDevelopmentLineHandle[] developmentLineHandle = prjArea
                .getDevelopmentLines();
 developmentLine = fAuditableClient.resolveAuditable(developmentLineHandle1,
         ItemProfile.DEVELOPMENT_LINE_DEFAULT, monitor);

for (IIterationHandle subiterationsHandle : subiterations) {
                IIteration subiteration = fAuditableClient.resolveAuditable(
                        subiterationsHandle, ItemProfile.ITERATION_DEFAULT, monitor); }
         
developmentLine.setCurrentIteration(subiterationsHandle);

i get the below error:

Exception in thread "main" com.ibm.team.repository.common.internal.ImmutablePropertyException

 Please carefully read Understanding and Using the RTC Java Client API   especially the part about working copy. You can not just modify stuff, you usually need a modifiable item (working copy).


From the same blog post read up how to setup the RTC SDK and the plain java client libraries. Use the Eclipse Java Search capability to search for setCurrentIteration and look at how the code is used in the RTC SDK e.g. unit tests.

Example from com.ibm.team.process.internal.client.tests.AbstractTeamProcessTest.setCurrentIteration(IDevelopmentLine, String) to get the workingcopy (called mutable copy in this context)

    
            IProcessItemService service = getProcessItemService();
            line = (IDevelopmentLine) service.getMutableCopy(line);
            line.setCurrentIteration(current);
            service.save(line, null);

The point of my reply was what to do and how to get at this information. It took me longer to type the response than to search for the API. If you want to continue with this kind of work, you should learn how to find API examples in the SDK.


You had several questions with a similar pattern and you would be able to answer most of your questions if you could do that.
