Netbeans保存掛起

我有一個編輯器TopComponent實現。出於某種原因，當我保存文檔時，會引發錯誤。下面列出的是錯誤。我不確定從這個例外開始。你能分享你所知道的嗎？感謝Netbeans保存掛起

EDIT 1

我有DataObject中且具有構造成一個新的MIME類型text/x-puml一個VisualElement子類。一旦我將這些改回text/plain，事情就開始奏效。我搜索了text/plain，看看我是否錯過了更改text/x-puml的任何內容，但找不到任何內容。有沒有其他的事情我應該改變MIME類型爲text/x-puml？

EDIT 2

似乎現在零星發生，但往往不是發生。如果我有自定義MIME類型，是否需要實現自己的SaveCookie或Savable？

stacktrace中的哪一行包含您編寫或編輯的類？ – 2013-05-11 21:55:47

這是有趣的部分，沒有一行提到我的代碼。但是我剛纔確實發現了什麼導致了這個問題。我有一個新的MIME類型的註冊'text/x-puml'，一旦我將它改爲'text/plain'，問題就消失了。你會碰巧知道我是否缺少任何配置。 – ShaggyInjun 2013-05-11 22:04:36

我還沒有在NetBeans中使用自定義MIME類型，所以我無法在那裏幫你。 – 2013-05-13 00:06:39

它看起來像一個信號燈問題。

系統無法保存文件，因爲該文件上存在排他鎖。另一個獨佔鎖（根據保存需要）是不可能的。

試着看文件處理。某處必須是鎖。

我有一個類似的錯誤，由於重命名，這是因爲該文件的鎖。所以我用了file's鎖定與primaryFile.lock()在：

WindowManager.getDefault().invokeWhenUIReady(new Runnable() 
{ 
    @Override 
    public void run() 
    { 
     if (obj.getDomainModel() != null) 
     { 
      String newName = obj.getDomainModel().getName(); 
      FileObject primaryFile = obj.getPrimaryFile(); 
      try 
      { 
       primaryFile.rename(primaryFile.lock(), newName, primaryFile.getExt()); 
       callback.updateTitle(newName); 
      } 
      catch (IOException ex) 
      { 
       String message = String.format("The model couldn´t be renamed to \"%s\"", newName); 

       LOG.warning(message); 
      } 
     } 
    } 
});

用它來保存文件或相似任何情況下。

我的例子我有同樣的問題，但重命名，而不是保存。但同樣的問題：先前打開的文件的鎖定。 – EliuX 2015-08-27 22:40:19

對不起 - 我誤解了你的回答。刪除downvote，謝謝澄清 – user2290362 2015-08-29 17:30:30

感謝您糾正。 – EliuX 2015-08-31 17:15:15
