    <p>I've added storage file to my codenameone application. In some event I wanna delete specific storage file and recreate it with some old filtered data and new data. It doesn't work well on deletion.</p> <p>First I create method for clear storage file in StorageManager class:</p> <pre><code>public void clearData(String pStorageTable){ Storage.getInstance().deleteStorageFile(pStorageTable); } </code></pre> <p>In other class I use this method like this: </p> <pre><code>// load all data of specific storage file // ... new DBManager().clearData(ThreeTrans.DB_NAME); // write old data with filtering of specific ID and new data // ... </code></pre> <p>here is method of write data:</p> <pre><code>public void write(ThreeTrans pTT){ if(store == null) { store = Storage.getInstance(); } DB_NAME = "TT"; if(!store.exists(DB_NAME)) { Hashtable depHash = new Hashtable(); String k = "1" + pTT.getNumber(); depHash.put(k, pTT.toString()); store.writeObject(DB_NAME, depHash); } else { Hashtable depHash = (Hashtable)store.readObject(DB_NAME); if (!depHash.containsValue(pTT.getNumber())) { String k = String.valueOf(getLastKeyNumber()); depHash.put(k, pTT.toString()); store.writeObject(DB_NAME, depHash); } } } </code></pre> <p>at first I was using this method for delete storage file:</p> <pre><code>public void clearData(String pStorageTable){ if(store == null) { store = Storage.getInstance(); } for (String str : store.listEntries()) { if(str.toLowerCase().startsWith(pStorageTable)) { store.deleteStorageFile(str); } } } </code></pre> <p>and after this problem this method changed to this;</p> <pre><code>public void clearData(String pStorageTable){ Storage.getInstance().deleteStorageFile(pStorageTable); } </code></pre>

    1. COWhat do you mean by "doesn't work well"? Do you get an exception? Your final data does not have all you need?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
