double convertedPercentage = new Double(percentage).doubleValue();
double multiplyNumber = 1 + convertedPercentage / 100;
Number newSalary = employee.getSalary().multiply(multiplyNumber);
employee.setSalary(newSalary);
Attention: The type of the parameters is String, because that is easiest to pass
from the ViewController, and it can be converted to any type you need.
Attention: This code assumes that you created a View Row class for the
Employees view. You can generate this class by going to the EmployeesView
editor, selecting the Java category and checking the EmployeesViewRowImpl
class checkbox.
Attention: The Number class referenced is oracle.jbo.domain.Number, not
java.lang.Number.
• Publish this method to the ADF Data Control by opening the Application
Module Editor, and going to the Client Interface category. Shuttle the new
increaseSalary method to the right.
Now you can choose between two customizations:
1. Call the increaseSalary method from a button where you pass the current
Employee Id and a fixed percentage of 10.
2. Call the increaseSalary method from a button where you pass the current
Employee Id and take the percentage from an input field on the page.
If you choose 1, apply the steps from section Creating a Button that Calls the Method
With a Fixed Percentage, and if you choose 2, apply the steps from section Creating a
Button that Calls the Method With Percentage From Input Field.
6.13.2. Creating a Button that Calls the Method With a Fixed Percentage
Before we generate the button into the page, we drag-and-drop it using the JDeveloper
Visual Editor, including the relevant ADF Bindings. That way we can see what it is we
need to generate.
Before making any customizations, ensure that the names of the used generator
templates are included in the sources, as explained in the section Finding Out Which
Generator Templates Are Used.
• Go to the page where you want to add the button (for example Employees.jspx)
in Design mode.
• Go to the Data Control Palette, and find the new increaseSalary method of the
Application Module.
• Drag-and-drop the increaseSalary method next to the other group level buttons.
• Choose Create – Methods – ADF Command Button. An Action Binding Editor
dialog opens. Don't close it yet.
We will now pass the current Employee Id, and a fixed value of 10 (to increase the salary
with 10 percent) to the increaseSalary method.
