As you probably know, the “Table” component allows you to use an out of the box filtering.
A while ago, I’ve been asked to execute a table filtering programmatically – that is, use a java code to automatically populate the filter.
In my current example I’m using a button to perform a filtering action. Of curse you can use the code in many other ways,
Well, here are the steps:
First, add a binding to the table with getter & setter:

In this post I will explain, how in a simple way you can use managed bean to perform a binding operation.
In case of using ADF for managing Human Task flows (BPM process), you sometimes want to perform post/pre actions to the native operation.
For example: you want the user to press the approve action, and in the background you want to call a Web service for some validations.
Here is how you do it:
to copy:
public String approveAction() {
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
OperationBinding validateNameOP = bindings.getOperationBinding("validateName");
Object resultCommit = validateNameOP.execute();
if (!validateNameOP.getErrors().isEmpty()) {
return null;
}
AttributeBinding status =(AttributeBinding)bindings.get("status");
if (status.getInputValue().toString().equalsIgnoreCase("Y")){
OperationBinding operationBinding = bindings.getOperationBinding("APPROVE");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
System.out.println("inside error");
return null;
}
}else{
return null;
}
return "refreshTaskFlow";
That’s it.
Just be sure, that both APPROVE & validateName operations are declared in the binding. Or else you will get nullPointerException.
Good Luck
