Buggy source:
public void createFolder(final IndexedFile file,final AsyncCallback<ActionImpact> callback){
  Dialogs.showPromptDialog(messages.createFolderTitle(),null,messages.createFolderPlaceholder(),RegExp.compile("String_Node_Str"),messages.cancelButton(),messages.confirmButton(),new AsyncCallback<String>(){
    @Override public void onFailure(    Throwable caught){
      Toast.showInfo(messages.dialogFailure(),messages.renameFailed());
    }
    @Override public void onSuccess(    final String newName){
      Dialogs.showPromptDialog(messages.outcomeDetailTitle(),null,messages.outcomeDetailPlaceholder(),RegExp.compile("String_Node_Str"),messages.cancelButton(),messages.confirmButton(),new AsyncCallback<String>(){
        @Override public void onFailure(        Throwable caught){
        }
        @Override public void onSuccess(        String details){
          IndexedFile folder=file;
          String aipId=folder.getAipId();
          String repId=folder.getRepresentationId();
          String folderUUID=folder.getUUID();
          BrowserService.Util.getInstance().createFolder(aipId,repId,folderUUID,newName,details,new LoadingAsyncCallback<IndexedFile>(){
            @Override public void onSuccessImpl(            IndexedFile newFolder){
              HistoryUtils.openBrowse(newFolder);
              callback.onSuccess(ActionImpact.UPDATED);
            }
            @Override public void onFailureImpl(            Throwable caught){

Fixed version (ground truth):

  Dialogs.showPromptDialog(messages.createFolderTitle(),null,messages.createFolderPlaceholder(),RegExp.compile("String_Node_Str"),messages.cancelButton(),messages.confirmButton(),new AsyncCallback<String>(){
    @Override public void onFailure(    Throwable caught){
    }
    @Override public void onSuccess(    final String newName){
      Dialogs.showPromptDialog(messages.outcomeDetailTitle(),null,messages.outcomeDetailPlaceholder(),RegExp.compile("String_Node_Str"),messages.cancelButton(),messages.confirmButton(),new AsyncCallback<String>(){
        @Override public void onFailure(        Throwable caught){
        }
        @Override public void onSuccess(        String details){
          IndexedFile folder=file;
          String aipId=folder.getAipId();
          String repId=folder.getRepresentationId();
          String folderUUID=folder.getUUID();
          BrowserService.Util.getInstance().createFolder(aipId,repId,folderUUID,newName,details,new LoadingAsyncCallback<IndexedFile>(){
            @Override public void onSuccessImpl(            IndexedFile newFolder){
              HistoryUtils.openBrowse(newFolder);
              callback.onSuccess(ActionImpact.UPDATED);
            }
            @Override public void onFailureImpl(            Throwable caught){
              if (caught instanceof AlreadyExistsException) {
