    <p>I hope I will get help, I will ask as general question:</p> <p>I am using a <code>JList</code>, and due to the <code>JList</code> not have a (value,text) (so I can display text and use the value in my code). Because of this leak I create <code>List</code> of object (myList), that work parallel with the <code>JList</code>. Every item I add to <code>JList</code> I add to <code>myList</code>, so the same index will contain the same info in the two objects (JList and mylist) I use the <code>JList.getselectedindex()</code> method to get the index and use it in <code>myList</code> to pup information...</p> <p><strong>The problem:</strong> is when I select value, the next value of the <code>myList</code> is overridden with the first value!!! Is this problem known?</p> <pre><code> mod_mp = new ModelMAPPING(); objects cotain values that ot exist in jList msgF.setTo(incom.userID);/////// set parter! if(isExCon==-1) { // not exist mod_mp.to = incom.userID; // incom is object that incom from another program mod_mp.SetCovFile(incom.userID+".html"); mod_mp.ConvName = incom.getBody(); boolean added= model_list.add(mod_mp); // add to mylist if(added) System.out.println(mod_mp._Hfile + " added"); model.addElement(mod_mp.ConvName);// add to Jlist by model HestoryFile(Htmlhead+tohis,mod_mp._Hfile);//create _Hfile and write to it:"tohis" string. } else { //exist@ // note isExcon return the index if exist else -1 model_list.get(isExCon).ConvName=incom.getBody(); mod_mp.SetCovFile(model_list.get(isExCon)._Hfile); HestoryFile(tohis, model_list.get(isExCon)._Hfile); }//end else </code></pre> <p>Here if file exists I just update the new text in the <code>JList</code> and set the current file</p> <p>The select of <code>JList</code> is:</p> <pre><code>msgF.setTo (model_list.get(jList2.getSelectedIndex()).to); // set that we will send To... mod_mp.SetCovFile(model_list.get(jList2.getSelectedIndex())._Hfile);//set the file jLabel5.setText( bringFromFile(mod_mp._Hfile));//tell the label to read that file </code></pre> <p>It works fine, but when I have two items in <code>JList</code> if I select any, the other is overridden!!! </p>

    1. COWhy don't you create and object that holds the values and pass it to your JList model? And you can override it's toString method so it'll display the text you want?

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.
