Developer's note for SPR 727
Paul Balm, March 6 2006

The problem reported is that when you create a proposal from PHS, you can't
save it in PHS, because there is no proper abstract. And you can't add an
abstract, because editing of the field is disabled.

The implementation in v12.2 is to allow editing of the abstract, but it has
also been decided to keep the SPR open to make a 'nice' implementation.

The nice implementation is this: In the 'Create Proposal' screen, add a
button 'Edit abstract'. As long as you haven't done that, you can't hit
'Create Proposal' (even better, it should give you an error message if you
do). The best thing to do here is of course to run the business rule
checker (because this is what detects the problem when you try to save from
PHS), but I'm not sure if that's possible as long as the proposal is not
in the database. When this is done, editing of the proposal abstract should
again be disallowed from PHS. 

This rule (when the abstract is editable) is implemented in the FieldMediator.
The abstract dialog is implemented by a class called AbstractDialog, which
has a main function for testing.
