Setting dynamic WHERE clause in VO

Question

Hi all,
I am using JDev 11.1.2.2.0. Example Scenario : In my application, In the first page, I am choosing a location value. In the second page I have a model based VO. The where clause of the query has to be set dynamically, based on the location what I am choosing in the first page. How to achieve this?
Regards,

First make sure you have defined your method in the AM Impl class.
Here is a post from a few topics back :

My question is how can I create a method that will return this information and use it from the ViewController ?For this:
1) Created a method in AMImpl
2) Exposed the method through Client Interface.
See this for more details:
http://docs.oracle.com/cd/E12839_01/web.1111/b31974/bcservices.htm#sm0212
Then
3) Define a method action binding in your jspx page(pagedef) where you want to access this method.
http://docs.oracle.com/cd/E15523_01/web.1111/b31974/web_adv.htm#ADFFD20984
4) Use the below code to call the AM method from View controller
DCBindingContainer bindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
OperationBinding operationBinding =
bindings.getOperationBinding("<method_name_in_AM>");
if (operationBinding != null) {
operationBinding.execute();
Object obj = operationBinding.getResult(); //obj will contain the value returned from your AM method
Step 4) is when you want to call that method from a bean.
You can also drag that method (from your data control) on your page. JDev will then ask if you want to make a form of it.
When you choose for that option, you will get an input field and a button. When you fill in the parameter in that input field and then hit the button, the method will be
executed and will use the inputed value as your parameter.
