One can use literal values for declaring a default value for an attribute, but I should be able to have initialization expressions (like Date#today())

JPA is the new standard for Java applications using relational databases. Allow generating code for the domain and persistence layers using Java/JPA.

Please provide a Maven plug-in that can generate code based on an AlphaSimple project.

It's great that one can model, generate prototypes, compose and test templates via the web site. But on an ongoing basis, code generation is triggered as part of an unattended automated process. For Java applications, Maven is the standard tool used.

Allow exporting all project files as a single operation.

It'd be great to have multiple users editing a same model at the same time.

Currently, one has to start the prototype again in order to reflect the latest changes in the model. Ideally, the prototype should update on the fly (preserving any existing data if possible).

Allow fetching a project's contents into my computer so I can version, archive etc.

Need support for object constraints (invariants). For instance, you cannot have more than 3 private projects if you have a free account.

Allow modeling acceptance tests. Imagine that tests could run automatically after a save, or that one could generate test code from the tests.

Allow generating domain/persistence code targeting C#/.Net

Open http://alphasimple.com/project/show/276#diagram on Chrome (Windows?).

The class diagram pane shows empty on Chrome (tested on Windows). Dragging the vertical sash (or the window border) causes the diagram to show for a split second (and stay if you are lucky). Seems the auto-resizing of the diagram is causing problems. Opening the diagram in its own tab works fine (for instance: http://alphasimple.com/mdd/diagram/rafael-276/alphasimple.uml ).

There. Said it.

If you have multiple comments, it seems only one will show.
