Modal Window Driving me Insane! disapearing table

Hi All,

so i have been at this for a few hours now and its slowly driving me insane, i cannot for the life in me figure it out.

here is a very simple working (or not as its broken somehow) example

I have 2 files

app.js

Ti.include('windows/window1.js');

var tabGroup = Titanium.UI.createTabGroup();
var main = Ti.UI.createWindow({title:'My Window',url:'main.js'});
var tab1 = Titanium.UI.createTab({
    title:'main window',
    window:main
});

tabGroup.addTab(tab1);

tabGroup.setActiveTab(1); 
// open tab group with a transition animation
tabGroup.open({
    transition:Titanium.UI.iPhone.AnimationStyle.FLIP_FROM_LEFT
});

var modal = Ti.UI.createButton({
    systemButton:Ti.UI.iPhone.SystemButton.INFO_LIGHT
});

main.setRightNavButton(modal)

main.open()

winopen();

modal.addEventListener('click',function(e)
{
    winopen();
});

windows/window1.js

var win = Ti.UI.createWindow({title:'My Window',barColor:'#13386c'});

var done = Ti.UI.createButton({
    systemButton:Ti.UI.iPhone.SystemButton.DONE
});
win.setRightNavButton(done);
var data = [
    {title:'Set 1'},
    {title:'Set 2'}
];
var table = Ti.UI.createTableView({
    style: Ti.UI.iPhone.TableViewStyle.GROUPED,
    data:data,
    rowHeight:50
});

win.add(table);

var winopen =  function()
{
    win.open({modal:true});
};

done.addEventListener('click', function()
{
    win.close();
});

Now as you would expect on initially loading, my app slides up the modal window1.js. all correct and working lovely

now you hit done and it take you back to the main window, which has a info button in the rightNavBar location

if you hit that button it fires a event which again opens the modal box

but this time there is no table to be seen!.

i just cannot understand why this works as expected

winopen();

but this doesnt

button.addEventListener('click',function(e)
{
    winopen();
});

can anyone put me out of my misery?

Thanks in advance

Richie

Try to add the table to the modal win when it opens.
So on the open event.
```
win.addEventListener('open', function(e) {
   win.add(table);
});
```
I think when you call close, the content of the window is released, so on a subsequent open, there is nothing to show.

function winopen(winName)
{
    winName.open({modal:true});
};

button.addEventListener('click',function(e)
{
    winopen(win);
});

Try that

It seems that the TableView is deleted each time the modal closes, so you need to define and add a new tableview each time you want to open the modal. If you define it once (as Tamas indicated) it doesn't work.

This code has been tested in Titanum SDK 1.5.1 / iOS 4.2 and works correctly:
```
var mainWin = Titanium.UI.createWindow();
var modalWin = Titanium.UI.createWindow();
var closeButton = Titanium.UI.createButton({title:"done",height:30,width:80});
modalWin.rightNavButton = closeButton;
closeButton.addEventListener("click",function(){modalWin.close();});    

var openButton = Titanium.UI.createButton({title:"open",height:30,width:80});
openButton.addEventListener("click",function(){
    var table = Ti.UI.createTableView({
        data:[{title:"Enter your own quote"},{title:"Quote Font Size"}]
    });
    modalWin.add(table);    
    modalWin.open({modal:true});

});

mainWin.add(openButton);
mainWin.open();
```

- So it seems this would be a bug then, right?

- …or a feature :-)

- I have also notified Appcelerator (through the Helpdesk) and am waiting for confirmation that this has been logged as a bug.

Hi Guys,

Thanks both for replying. I can tell you though that neither option results in a working window with table.

Daniel is correct in saying that the contents of the window appear to be released. if i remove the initial call to winopen and run the on event against the button the window is drawn correctly.

closing and then reopening results again in the missing table.

i will keep plugging away at it and see if i can come up with anything further

thanks again

- Okay i finally got it to work by wrapping the whole window creation in a function and calling that function from the eventListener
```
window1 = {};
window1.init = function() {
 // create your window here and open it
};


then in app.js

button.addEventListener('click',function(e)
{
    window1.init();
});
```
  not the best solution (certainly need to check the performance of it) but it works
