RE: [Springframework-rcp-dev] spring-rich-forms: how to implement AbstractTableMasterForm using GlazedLists model archetype

[Larry S. <lst...@ny...>]

Hi Joe,

I'm sure I'm missing something unique in your application, but it seems that
you are asking about recreating a significant chunk of code, but I don't see
why you would need to do so.

The AbstractTableMasterForm already creates a GL around the bound property's
collection.  The current Form instances already handle dealing with
individual elements of the collection, so I can't see why you would need to
create your own FormModel implementation.

As I said, I'm obviously missing something, so maybe you can explain why the
existing implementations will not work for you.

Thanks,
Larry.
