    1. COI know there are limitations and I'm close to the edge. That's why I'm trying to get a feel for which side of the edge I'm on. I don't think I'm too upset if I can't get an active assertion that this is a safe cast, I know better than to expect this is standard usage and generics have generally been a great tool and very useful in the past for me. the Transformer is an interface, and not so simple as the example of course. A DateTransformer concept would be an implementation that expects a certain date format, you could have a PercentageTransformer, MonthTransformer, or custom types.

    2. COnot going outside of standard Java. Four reasons are compatiblity and portability, availabilty of libraries on other machines, collaboration with others, and I have a mental dislike of huge libraries/language extensions which are more complex to use than it is to make it yourself.

    3. COsorry, comment took more than 1 box. I think we are commenting in parallel :P. The transformer is typed, but that is another file. The issue is that type parameter is only applicable inside a transformer, and more specifically it is fixed the instant you instantiate it. But a cell may have it's value and transformer removed and replaced with a different transformer and recalculated. This is why I'm trying to take complexity out of the cell and the spreadsheet to make it something that only applied to the data.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
