Persistent ScriptUI Dialogs that can be shown several times.

Question

Hi all,
I love ScriptUI and all its possibilities. But every time I try something new I fail for at least some days
Here is my newest conundrum: I try to do something that involves selecting a menu item along the road. Assembling all menu items in a tree view takes up to 20 seconds so I would like to build that dialog only once and call it repeatedly from the main dialog.
The test setup illustrates the problem:
var w = new Window("dialog");
var d = new Window("dialog");
d.closeDlg = d.add("button", undefined, "Close Dialog");
d.closeDlg.onClick = function () {
     d.hide();
w.openDlg = w.add("button", undefined, "Open Dialog");
w.cancelElement = w.add("button", undefined, "Cancel");
w.openDlg.onClick = function () {
     d.show();
w.show();
The first click on "Open Dialog" looks as it should. But when you cancel d and click again, the sub dialog contains nothing and is off the screen.
I can correct the latter (d.center() before d.show() ), but not the former.
Help says "When a window or container is hidden, its children are also hidden, but when it is shown again, the children retain their own visibility states."
I tried to show the children in a d.onShow() function but so far with no success.
So my question is (thank you for reading this far):
Can this be done? Can I build a complicated dialog once and call it several times from a different dialog?
The only other option I can think of is to build an ugly super-dialog that contains all the controls of the main and of the sub dialog. bah.
Thank you
Gerald

Duh...
Peter I feel stupid. Of course. Thank you for pointing that out to me
I updated the zip in the mentioned post, in case anyone's interested.
Harbs, I save a lot of details in the list items themselves instead of maintaining an additional array. So removing all listitems would mean I lose e.g. the info which menu item is applied to which script.
So rebuilding the list would mean quite some changing of my datamodels. I will keep that in mind for future projects, though. Thank you
