Description

I have a listview, which displays remote images of different dimensions. While images are loaded, I show defaultImage with spinner. Here's a template I have for this 
{
    bindId: 'main',
    properties: {height: Ti.UI.SIZE},
    childTemplates: [
        {
            type: 'Ti.UI.ImageView',
            bindId: 'image',
            properties: {
                width: Ti.UI.SIZE,
                height: Ti.UI.SIZE,
                defaultImage: 'icon_spinner_wide.png'
            }
        }
    ]
}
Once list is displayed, default image is shown, and ImageView has height and width according to default image. The problem is that as soon as remote image is loaded (and cached), it is displayed, but the height remains same as it was for default image. If I open the list 2nd time, it works fine, because the image is not remote anymore and could be shown immediately, without default image. I've tried to add event listener to 'load' event for image (in order to adjust list item height), so template looks like this: 
type: 'Ti.UI.ImageView',
bindId: 'image',
properties: {
    width: Ti.UI.SIZE,
    height: Ti.UI.SIZE,
    defaultImage: 'icon_spinner_wide.png'
},
events: {
    load: function(e) {
        alert('hello');
    }
}
but unfortunately as soon as 'load' event handler is declared, I get following error on listview.setSections: *** setObjectForKey: object cannot be nil (key: section) If I add handler for click event, it works. Probably these 2 issues are connected. Also it works on Android (both resize after remote image is loaded and load event).

    Hello , the new release of the titanium SDK(5.1.0) should fix the current bugs with the imageView. The image will now be resized to it's original size or to a specified one. Example code : 
     
   
   var win = Ti.UI.createWindow({
       backgroundColor: 'white'
   });
   var myTemplate = {
   
       properties: {
           height: 100,
           backgroundColor: 'red'
       },
       childTemplates: [{
           type: 'Ti.UI.ImageView',
           bindId: 'image',
           properties: {
               width: 100,
               height: 100,
               defaultImage: 'default_app_logo.png',
               backgroundColor: '#ccc'
           }
       }]
   };
   var sections = [
       Ti.UI.createListSection({
           items: [{
               image: {
                   image: 'http://cdn.slidesharecdn.com/profile-photo-appcelerator-48x48.jpg?cb=1416396285',
                   backgroundColor: 'blue',
                   width: Ti.UI.SIZE,
                   height: 200
               }
           }]
       })
   ];
   
   var listView = Ti.UI.createListView({
       templates: {
           'template': myTemplate
       },
       defaultItemTemplate: 'template',
       sections: sections,
       top: 20
   });
   
   
   win.add(listView);
   win.open();
