Hi all, We have the following destination hierarchy defined in our application- continent, country, state, city and locale. We thought of providing the users a drop down in BRMS to select the appropriate values. Current selection should based on the previously selected destination value. For example - If the country is selected as 'UK' then all the states in 'UK' should be populated and shown as the state. This works perfectly well on using the conditional enumeration feature. Currently we have around 6 million records defined and loading all of these during the application start poses a performance issue. Is there a way to tweak this behaviour during BRMS start up. Our rquirement is to load only the continent data first and upon selecting the continent, the application should make a call to the underlying database to retrieve the country related information and so on. I firmly believe there should be a way to do this. If there is currently no provision to do this we are ready to tweak the GWT code to make this work. If someone can provide a little hindsight on where to start from, it would be really helpful. Thanks a lot. -- View this message in context: http://www.nabble.com/Data-enumeration-tp16659931p16659931.html Sent from the drools - user mailing list archive at Nabble.com.
