I have a new RCP application that allows users to maintain patient demographics data via a UI form. It is a fairly deep object graph and data of this model is pre loaded for every patient. I need to add the flexibility for users to write rules via a UI tool and customize how and when they want data in the model should be changed and control things in the UI form, such as set focus, set required, enable/disable field, show message box ...etc. They also want the ability to group and when to fire rules based on three different levels such as form, dialog or field. They could build one or more rules to the form or/and dialogs/fields in the form. They could set up to fire rules at the open/close of the form or dialog or even when a value is changed/lost focus on a field. I’d like to have your opinions if this will fit well with Drool rule engine. Is this a bit overkill for what I want to do? Has anyone used Drool for something similar to this? Thanks. -- View this message in context: http://n3.nabble.com/Is-this-overkill-to-use-a-rule-engine-tp90400p90400.... Sent from the Drools - User mailing list archive at Nabble.com.
