Hi, I'm doing my first cairngorm project, and trying to adapt best practices and conventions.
Well, I have a screen in which the user should upload multiple files from his computer, much like flickr's one <http://www.flickr.com/photos/upload/> . The view will contain a DataGrid, "upload" button and "select files" button, that allows the user to select files. When user selects one or more files, their details will be added to the DataGrid and upon clicking the "upload" button the upload process begins. This is a very simple case to do without cairngorm, but I can't find a decent way that follows the cairngorm mvc architecture. For the user to start selecting files he'll need to use the FileReferenceList.browse(), where would that object should reside ? I'm not sure if it should sit in the model, created by the view as a VO or... ? Lets say I have the FileReferenceList object. the file browsing smells like a view related as it interacts with the user, if so, and following the rule that dictates that only commands can change the model, then the FileReferenceList should be instantiated by the view so that it won't change a model object directly. That is one thing, the other one is keeping the business the only way data can be passed to the server. Upon clicking the "upload" button, how can the matching command us the business to upload the FileReferenceList ? Thanks a lot and good night. Cheers, Almog Kurtser.
