From Jdeveloper 12.2.1.4 Don't returned bind variable value in Applcation Module.
Descriprion:
1. Create View Object based on query: select * from dual where dummy = :dummVar
2. Create bind variable dummvar in query tab
3. Add ViewObject to Application Module
4. Open view object instance and set value for bind variable
Generated bcs file with next code:
@AccessorParameterExpression(accessorName="DualVO1", name="dummVar")
def dummVar_DualVO1_BindVariable_BoundParameter()
{
"test"
}
5. Run instance in Application module.
Result: value is empty.
PS: In jdev 12.2.1.3 it was worked properly.

Removed sections that described obsolete use cases for bind variables. The generation of bind variables on custom view object classes is no longer an option in the Select Java Options dialog that you open from the Java page of the view object overview editor in JDeveloper. The recommended way to allow UI fields to update bind parameter values is through view criteria
