How to get a WorkingCopy of a hierarchy


Susan Hanson (1.6k2189193) | asked Jun 13 '14, 9:06 a.m.
I am working on re-creating a team hierarchy from one project area to another.

I have gotten down to getting an IWorkingCopyManager as well as creating a new ITeamAreaHandle and getting the ITeamAreaHierarchy from the project area.

However, I am getting the ImmutablePropertyException on the teamHierarchy.addRoot(teamAreaHandle, timeline).

I assume this is because I have the hierarchy and not a hierarchyWorkingCopy (if one exists).

Has anyone done this that they could share a snippet?

here is some code I have for that  copy team area from src project (and server maybe) to dest project (and server maybe)

Thanks Sam .. this works fine ... however, I don't see that the Summary and Description of the team area is being duplicated over.

I attempted to add something in the block with
                    destTeamArea.setName(srcteamarea.getName());
                    destTeamArea.setProcessName(srcteamarea.getProcessName());
...
but while I can get the description using srcteamarea.getDescription();  I didnt' see a setDescription() on the destTeamArea object.  Is that correct?  Is there any way to do this?  We use the Description field for ALOT of things, so I really need to find a way to  get that over as well.

Susan


sam detweiler commented Jun 14 '14, 7:41 a.m. | edited Jun 14 '14, 7:51 a.m.

yeh, I didn't find it either.  and getDescription() returns an IDescription object, not String.

there must be a way however as the UI does it.. I looked thru the code for the team area editor, but its as obtuse as ever.

the TeamArea object has setDescDetails, and setDescSummary,
which match the fields in the IDescription object.


Susan Hanson commented Jun 16 '14, 9:28 a.m.

So I don't have any type of setDesc* methods on the ITeamArea that I can see in my eclipse, perhaps those were added more recently than 4.0.5?

As well, I have this working (NICE!) with the exception of the Description and Summary, which I'm looking into more.


sam detweiler commented Jun 16 '14, 9:45 a.m.

note that I said 'TeamArea' NOT ITeamArea..

the interface, ITeamArea, does not have methods
the implementation class,  TeamArea, does

I think its moot now, as the IDescription object can be accessed to set the fields and
on (process/team) area save its values are used.


Susan Hanson commented Jun 16 '14, 10:24 a.m.

Well, except that so far, I can getDescription() to get the IDescription object, but again, I can't set the values that I want, nor can I seem to set the description back into the team area.

Please have a look into the snippets that come with the Plain Java Client Libraries. There is some explanation here too: https://rsjazz.wordpress.com/2013/09/18/deploying-templates-and-creating-projects-using-the-plain-java-clients-library/

The code looks funny.....

if (area == null) {
        System.out.println("Trying to create Project Area: " + projectName);
        area = service.createProjectArea();
        area.setName(projectName);
        area.setProcessDefinition(processDefinition);
        IDescription description = area.getDescription();
        description.setSummary("Project to be used running the RTC Extension Workshop");
        area = (IProjectArea) service.save(area, monitor);

some apis are by value (get/set) and some are by reference.(access thru )

there is NO indication that the IDescription object is by reference

how does get/setSummary relate to the IDescription object Summary field?
as setSummary is not deprecated.

this should be the new code.. (tested on same repo) (my code assumes different rtc repos all the time)

                    destTeamArea.setName(srcteamarea.getName());
                    destTeamArea.setProcessName(srcteamarea.getProcessName());
                    destTeamArea.setProcessSummary(srcteamarea.getProcessSummary());
                    destTeamArea.setProjectArea(destproject);  
                    destTeamArea.getDescription().setSummary(srcteamarea.getDescription().getSummary()); //new
                    destTeamArea.getDescription().setDetails(copycontent(srcteamarea.getDescription().getDetails(),((ITeamRepository)srcproject.getOrigin()).contentManager())); //new
////
worker function
    private static IContent copycontent(IContent in, IContentManager icm)
    {
        IContent out = null;

        // get the content of the content object.
        try
        {
            if (in != null)
            {        
                IAuditableCommon auditable = (IAuditableCommon) destauditableClient.getTeamRepository().getClientLibrary(
                        IAuditableCommon.class);               
                // make an output stream for the content manager
                OutputStream os = new ByteArrayOutputStream();
                // get the content of the content object.
                icm.retrieveContent(in, os, null);
                // extract the bytes, need the object twice
                byte[] bytes = os.toString().getBytes(in.getCharacterEncoding());
                // make a content object on the destination system

Yea, I had went down this path a few days ago already.  At the same place I create the TeamArea and set it's name, I attempted to set the Summary and Details from the srcteamarea:
                    IDescription x = srcteamarea.getDescription();
                    IDescription y = destTeamArea.getDescription();
                    y.setSummary(x.getSummary());
                    y.setDetails(x.getDetails());

I'm on the same server, so I just did a straight setSummary() and setDetails() from the Summary and Details directly in the srcteamarea.  However, the setDetails() call gets
com.ibm.team.repository.common.internal.ImmutablePropertyException


sam detweiler commented Jun 17 '14, 9:14 a.m.

the code above worked perfectly, copy team area from project a to project b, including the description.

you of course have to have the working copy of the destination project area.

Susan, did this work for you? I updated the code in the 1st answer as well.
