Unsolved Model-View-Delegate Problem

[Anas A. Ismail]

Hello everyone,
I was extending the Photo Albums viewer recently, by making the app loads the images from local machine, I replaced the XmlListModel with FolderListModel, and set the folder property like this
model: FilesModel { id: rssModel; folder: mainWindow.getFolderUrl()}
where getFolderUrl(), is a method the returns fileDialog.fileUrl+"/"

The main problem is when I load new folder, it makes all albums points to the same url.
