BIG Problem about save selection!

Hi,everybody!

I an new about js.  A few day ago, I wrote a "saveSelection dialog.jsx". It can work in "Dialog" windows type. BUT it can't work immediately while I change "Dialog" to "Palette", because I want to the palette stay the screen so as to I can use when I need.

Could you help ME!

Forgive me poor english, thanks in advance for your help

// JavaScript Document
//(function () {    var doc=app.activeDocument,u,array=new Array();;
var w=new Window("palette"),//dialog is work
listPnl=w.add("panel");
//listPnl.size=
entry = listPnl.add ("edittext", u," Type the first letter"); //请输入首字进行查找
entry.graphics.font = ScriptUI.newFont ("Arial", "", 16);
entry.size=[200,30];
entry.active = true;
G_Slist=listPnl.add('group');
G_Slist.orientation='row';
Slist=G_Slist.add('listbox');//,u,u,{multiselect: true}
Slist.alignment='left';
Slist.size=[140,100];
Slist.scrolling=true;
orderG=G_Slist.add('group');
orderG.orientation='column';
orderPnl=orderG.add('panel');
orderPnl.margins=2;
orderPnl.size=[50,100];
orderPnl.alignChildren=['fill','center'];
var select=orderPnl.add("button", undefined, "SEL");
select.size=[40,20];
var up =orderPnl.add ("button", undefined, "Up");//Up
up.size=[40,20];
var down = orderPnl.add ("button", undefined, "Down");
down.size=[40,20];
addSel=listPnl.add('button{text:"+ add 增加选择到清单"}');
addSel.size=[200,20];
deleteSel=listPnl.add('button{text:"- delete 从清单中删除"}');
deleteSel.size=[200,20];
