Why does Deletion of an Iteration programatically throw ProcessDataValidationException ?

Following is my code to delete iteration from a project area :

for (Object obj : itemManager.fetchCompleteItems(
Arrays.asList(workingDevLine.getIterations()),
IItemManager.DEFAULT, monitor)) {

   IIteration iter = null;
   if (obj instanceof IIteration) {
    iter = (IIteration) obj;


     workingDevLine.removeIteration(iter);
    }

I am recieving the following error message :

com.ibm.team.process.common.service.ProcessDataValidationException: Iteration 'FY14Q3' has a backpointer to timeline 'Project_Timeline', but the timeline does not contain it.

An explanation about this error might be helpful.

It looks like your iteration is referencing a project timeline. Did you delete the project timeline that iteration was associated with?

No, I just wanted to delete a particular iteration from the project timeline. The project timeline is not deleted.

When you use IDevelopmentLine.removeIteration() to remove an iteration, you should also have to remove the reference of development line from the iteration that is about to be removed.

For example:

developmentLine.removeIteration(iteration);
iteration.setDevelopmentLine(null);

I tried implementing your suggestion. I am getting the following error message on save operation :

com.ibm.team.process.common.service.ProcessDataValidationException: timeline may not be null

If you just want to delete a iteration, you can use com.ibm.team.process.client.IProcessItemService.delete(IProcessItemHandle, boolean, IProgressMonitor) on client site.

Thanks for the alternative. I tried using the method. The problem with this approach is that it renders the existent workitems using the iteration in an unstable state. Instead I tried this :com.ibm.team.process.client.IProcessItemService.archiveProcessItem(IProcessItemHandle, IProgressMonitor).

It did archive the iteration still I was getting work items in an uunstable state. I just added the workingDevelopmentLine.remove operation after this and it worked for me. We now have unnecessary iterations archived. For the workitems using the iteration, the planned for field has value :"iteration-name"+"(archived)".

The code now looks like this :

service.archiveProcessItem(working_Iteration, null);

workingDevLine.removeIteration(working_Iteration);

It's all about the answers!
