Pain: If modifying standard tables can indicate pain of upgrade, forms can really make you feel every upgrades a mammoth task. Just to feel the numbers, there has been 7 minor versions or roll-up in the last three years. So every upgrade might eat up considerable time with more and more form changes. This further amplifies when the solution is further localized.
Solution:A framework that lets designing small reusable form portions and dynamically add it to any form (standard/customized) at a place holder specified. Not limiting there this framework can also redirect events(create, delete, double click) specifically from these form parts to the handler assigned.While the Ax2012 form part which in similar lines to this has some limitations this framework has know such capping and is much powerful.
Pleasure:Literally Zero upgrade but a better win is the ability to create reusable form components. The designer associated with this is simple enough even for a functional consultant to add/delete features to other forms.
