Combining Multiple Queries and Parameters into One Operation
By Shay Shmeltzer-Oracle on Dec 28, 2010
This question came up twice this week and while the solution is explained in a couple of previous blog entries I did, I thought that showing off the complete solution in a single video would be nice.
The scenario is that you have two VOs with queries that are based on a parameter, I showed in the past how to create a parameter form that executes the query - and you can do this for both.
But what if you actually need just one value to drive both queries? How do you combine two parameter forms and two buttons into one?
This is what this video shows you. The steps are:
Creating two parameter forms
Setting the value of a parameter in the binding tab
Creating a backing bean to execute the code for one button
Adding the code to execute another operation
Remarking the parts that can be dropped from the screen
