I am getting error while adding existing child of one team area to another team area using plain java API. Adding similar child in different Team areas of a project area is allowed in RTC UI so this should be possible using API too.The code creates the team hierarchy the first time it runs but it throws error if I want to have same child in some other team area. The error is thrown at below line of the code : projectArea.getTeamAreaHierarchy().addChild(rootTeamAreaHandle, childTeamAreaHandle);
Error: " Exception in thread "main" com.ibm.team.process.common.TeamAreaHierarchyException: Child team area is already part of this team area hierarchy "
My relevant code :
public void createTeamArea(ITeamRepository repo, String projectName, String rootTeamAreaName, String childTeamAreaName, String grandchildTeamAreaName,String teamAdmin, IProgressMonitor monitor) throws TeamRepositoryException {
IProcessItemService processItemService= (IProcessItemService) repo.getClientLibrary(IProcessItemService.class);
ITeamAreaHandle rootTeamAreaHandle;
ITeamAreaHandle childTeamAreaHandle;
ITeamAreaHandle grandchildTeamAreaHandle;
IProjectArea projectArea = getProjectAreaByName(projectName, monitor);
List<ITeamAreaHandle> teamlist = new ArrayList<ITeamAreaHandle>();
teamlist = projectArea.getTeamAreas();
ITeamAreaHandle rootTAHandle = findTeamAreaByName(teamRepository,teamlist, rootTeamAreaName, monitor);
if(!(rootTAHandle == null)){
rootTeamAreaHandle = (ITeamArea)repo.itemManager().fetchCompleteItem((ITeamAreaHandle)rootTAHandle, IItemManager.DEFAULT, monitor);
}
else {
rootTeamAreaHandle = createTeamArea(repo, projectArea, rootTeamAreaName, teamAdmin);
}
if (!childTeamAreaName.equals("NULL"))
{
ITeamAreaHandle childTAHandle = findTeamAreaByName(teamRepository,teamlist, childTeamAreaName, monitor);
if(!(childTAHandle == null)){
childTeamAreaHandle = (ITeamArea)repo.itemManager().fetchCompleteItem((ITeamAreaHandle)childTAHandle, IItemManager.DEFAULT, monitor);
}
else {
childTeamAreaHandle = createTeamArea(repo, projectArea, childTeamAreaName,teamAdmin);
}
ITeamAreaHandle grandchildTAHandle = findTeamAreaByName(teamRepository,teamlist, grandchildTeamAreaName, monitor);
if(!(grandchildTAHandle == null)){
grandchildTeamAreaHandle = (ITeamArea)repo.itemManager().fetchCompleteItem((ITeamAreaHandle)grandchildTAHandle, IItemManager.DEFAULT, monitor);
}
else {
grandchildTeamAreaHandle = createTeamArea(repo, projectArea, grandchildTeamAreaName,teamAdmin);
}
if (!(projectArea.getTeamAreaHierarchy().getParent(childTAHandle)== rootTAHandle))
{
projectArea = (IProjectArea) projectArea.getWorkingCopy();
projectArea.getTeamAreaHierarchy().addChild(rootTeamAreaHandle, childTeamAreaHandle);
projectArea.getTeamAreaHierarchy().addChild(childTeamAreaHandle, grandchildTeamAreaHandle);
}
processItemService.save(new IProcessItem[] {projectArea} , monitor);
}
Method findTeamAreaByName () :
public static ITeamAreaHandle findTeamAreaByName(ITeamRepository teamRepository, List<ITeamAreaHandle> teamAreaHandleList, String teamAreaID, IProgressMonitor monitor) throws TeamRepositoryException{
for(ITeamAreaHandle teamAreaHandle : teamAreaHandleList){
ITeamArea teamArea = (ITeamArea)teamRepository.itemManager().fetchCompleteItem(teamAreaHandle,ItemManager.DEFAULT,monitor);
if(teamAreaID.equals(teamArea.getName())){
return teamAreaHandle;
}
}
return null;
}

One answer
The error "Child team area is already part of this team area hierarchy" is thrown when any team area in the hierarchy is a parent of the team being added anyplace in the hierarchy.
You should be able to address this by using method com.ibm.team.process.internal.common.util.TeamAreaHierarchy::reparent(ITeamAreaHandle newParent, ITeamAreaHandle child) instead of addChild() when the team area already has a parent.
The code in the RTC IDE that implements drag-and-drop of team areas to move calls promoteToRoot() when the target is an instance of IProjectArea and invokes reparent() otherwise.
