Import Failing....

I am trying to perform an import with the binding parm set to UPDATE_EXISTING and it is failing with a "Duplicate child name found." I think it started failing when I upgraded to 2.1, but not completely sure.I did a simple test of creating a space folder with one file of content. Exported the cont

I'm having the exact same problem, so I decided to create a Test where I can import content into the repository. The first time works OK, second one fails with a DuplicateChildNodeNameException. Changing the UUID binding parameter does not affect the result.

That's a bit annoying if you want a module to bootstraps every time the server starts. For example, if your module has a template and you want to reinstall the module because that template changed, you might probably want to bootstrap that module again (mind there's still no "module uninstaller" available yet). Hence, duplicate child node name constraint stops you from doing that.

Here's the code for the test I'm running:

ImportTest.java

public class ImportTest extends BaseSpringTest
{
    public void testImport()
    {                       
        importFile("import.xml", "/app:company_home");
        
        setComplete();
        endTransaction();
    }
    
    private void importFile(String file, String destination)
    {        
        ImporterComponent importer = (ImporterComponent)this.applicationContext.getBean("importerComponent");
        
        InputStream viewStream = getClass().getResourceAsStream(file);
        InputStreamReader inputReader = new InputStreamReader(viewStream);
        BufferedReader reader = new BufferedReader(inputReader);

        Location location = new Location(new StoreRef(StoreRef.PROTOCOL_WORKSPACE, "SpacesStore"));
        location.setPath(destination);
        
        importer.importView(reader, location, new TempBinding(), null);
    }
    
    private static class TempBinding implements ImporterBinding
    {   
        /* (non-Javadoc)

        {

            return UUID_BINDING.UPDATE_EXISTING;
        }

If my memory serves me correctly (after hours of pouring through code), the import will only "update" a file based upon UUID, not the filename.

The UUID MUST Match between the existing system and the imported file xml. Your XML file you are importing does not specify a UUID for the file so it will assume it needs to create a new one and attempt to do so (thus the duplicate child node).

Hope this is usefull.

Well, your memory is just fine, because that was the problem. By not specifying a UUID for the content I was bootstraping, the UUID binding was being ignored. Setting a UUID for each content inside the bootstrap xml files did the trick..

Thank you very much!
