A couple of threads on the Oracle Visual Builder Cloud Service forum asked about writing code in buttons in VBCS that compares values entered in a page to data in business objects and perform conditional navigation based on the values. In a past blog I showed the code needed for querying VBCS objects from the UI, but another sample never hurts, so here is another demo...
For this demo I'm going to show how to do it in a login flow - assuming you have a business object that keeps usernames and passwords, and you want to develop a page where a user types a user/pass combination and you need to verify that this is indeed a valid combination that exist in the business object.
(In reality, if you want to do user authentication in VBCS - you should use the built in security frameworks and not code it this way. I'm just using this as an example.)
Here is a quick video of the working app - with pointers to the components detailed below. Read the complete article here.
