> currently every component that requires the markup to be in an
> associated file must be derived from Panel. Every component that want
> it's markup "inline" must be derived from Fragment. I've changed that
> and moved the respective source code into something I called markup
> sourcing strategy. I'm not sure it's the best name, so feel free to
> suggest other names. Such a strategy can be provided to any component
> via
> public IMarkupSourcingStrategy getMarkupSourcingStrategy();
> Obviously it makes sense that only one strategy can be associated with
> any component. Each strategy has its own implementations to provide
> the correct markup, handle the header contribution, necessary changes
> to the open tag and it renders the component body appropriately.
> Changing a FormComponent to a FormComponentPanel is now as simple as
> subclassing getMarkupSourcingStrategy(). And it easily be changed to
> become a "FormComponentFragment"
> I've attached a patch (draft) against 1.5 trunk which successfully
> passes all tests in core. I wonder what you think about the idea.
