Scrollbar truncates contents (using ScriptUI)

[Guest]

I have problem with generating long dialog. I add scrollbar, create 41 rows, but in real created are only rows to 31. (I added higher scrollbar to see whole last elements)

var w = new Window('dialog');
w.maximumSize.height = 400;
var panel = w.add ('panel {alignChildren: "left"}');
var scrollGroup = panel.add ('group {orientation: "column"}');

var scrollBar = panel.add ('scrollbar {stepdelta: 10}');

for (var i = 0; i <= 40; i++) {
var group = scrollGroup.add ("group");
group.edit = group.add ("edittext", undefined, scrollGroup.children.length);
}

// Move the whole scroll group up or down
scrollBar.onChanging = function () {
scrollGroup.location.y = -2 * this.value;
}

w.onShow = function() {
// Set various sizes and locations when the window is drawn
panel.size.height = w.size.height-20;
scrollBar.size.height = w.size.height-20;
scrollBar.size.width = 20;
scrollBar.location = [panel.size.width-30, 8];
scrollBar.maxvalue = scrollGroup.size.height - panel.size.height + 15;
};
w.show();

hi, maybe the code below will help you

var myWindow = new Window('dialog','test',undefined)
	
var len = 100
var size = 1
	
var myTopPanel = myWindow.add('panel',undefined,'scroll')
myTopPanel.size = [200,500]

var myGroup = myTopPanel.add('group')
myGroup.orientation = 'column'
for(var i = 0; i < len; i++){
	myGroup.add('edittext',undefined,'item '+(i+1))
	size+= myGroup.children[i].preferredSize[1]
}
myGroup.maximumSize.height = myGroup.children.length*size
	
var myScrollBar = myTopPanel.add('scrollbar')
myScrollBar.stepdelta = myGroup.children.length
myScrollBar.jumpdelta = myGroup.children.length*10
myScrollBar.onChanging = function(){myGroup.location.y = -1*this.value}

myWindow.onShow = function(){
	myScrollBar.bounds = [myTopPanel.size.width-20,0,myTopPanel.size.width-5,myTopPanel.size.height-10]
	myScrollBar.maxvalue = myGroup.size.height-myTopPanel.size.height+10
}
myWindow.show()
