ADF UI: Made Some Operations in Page Load or During Page

• Steps:
• Go to java tab in view object (say: xVO).
• Add the ViewImpl java class
• Define new public method execute the operation you want in the VO (ex: filter data by view criteria). 
• Note: you may need this.executeQuery() after you code to update VO data
• Add the method to client interface of this VO
• Add VO to Application Module
• When it runs:
• Page Load:
• Drop the method from 'Data Control' into your bounded task flow as start activity
• Open binding and set the method parameters to other bind variables, literal values, or keep it blank
• Make sure the task flow share AM instance across pages in it
• Make the next page use the same VO instance in Data Control you used to create method binding.
• During Page:
• Using this code sample in bean

    public void RefreshAction(ValueChangeEvent valueChangeEvent) {

        BindingContainer bc = BindingContext.getCurrent().getCurrentBindingsEntry();

        OperationBinding oper = bc.getOperationBinding("Your Operation Binding");

        oper.getParamsMap().put(key, value); //if you have parameters and you keep it blank

        this.setValueToEL("#{bindings.parameterValue.inputValue}", valueChangeEvent.getNewValue()); //if you set parameter value to another bind variable, you need to refresh it

        oper.execute();

    }
