...service.cmr.repository.datatype.TypeConversionException

[thierensbart]

Hi,

I got an app that gets a complete folder-structure from an Alfresco-system.

Everything goes well untill it throws a weird error at me.

This is a snippet of my function (bold line is where the Exception is thrown:

Reference ref = new Reference(getStore(), parent.getUuid(), null);
      
      RepositoryServiceSoapBindingStub repoService = WebServiceFactory.getRepositoryService();
      
      QueryResult queryResult = repoService.queryChildren(ref);
      ResultSet resultSet = queryResult.getResultSet();
      ResultSetRow[] rows = resultSet.getRows();
      if((rows != null) && rows.length > 0){
         for (ResultSetRow row : rows) {
            ResultSetRowNode rowNode = row.getNode();
            //make a MigrateFolder for each row IF it is a folder
            String uuid = rowNode.getId();
            Reference subRef = new Reference(_store, uuid, null);
            Node subNode = repoService.get(new Predicate(new Reference[]{subRef}, getStore(), null))[0];
            NamedValue[] subProperties = subNode.getProperties();
            if(isFolder(subProperties)){
               MigrateFolder folder = createFolder(subProperties, parent);      
               getSubFolders(folder);
            }
         }
      }

Any idea what might be the problem?
