Hello, I'm currently evaluating isis for a new application. One of the requirements is that users should be able to import and export data as spreadsheets.
There doesn't seem to be file choosing views shipped with the dnd viewer, so I've been trying to roll out my own (the usual pair of a text field and button that opens a file chooser). Unfortunately, I got overwhelmed by all the concepts involved (views, view requirements, factories, specifications and builders, facets and their factories, object adapters, the various contexts...) and their relations, and ultimately have been unabled to get anything working so far. Also, the app will be deployed in client/server mode, and I can't figure out whether domain object methods are run on the server or on the client. As a consequence, I don't know whether the argument to the import action should be a reference to the file (a la java.io.File) or its contents (a wrapper on byte[]). I'd be grateful if someone could give me a summary of the classes I have to implement. Thanks, Christophe
