Getting a value of an input text component in backing bean

Question

I have created an input text component on a page where I will be entering a number, setting Autosubmit feature as true. ValueChangeListener property is set as #{test.displayTable} where displayTable is a method defined in test managed bean.
Now I know to fetch the value entered in input text component by creating a RichInputText variable in Advanced property.
But in case the Advanced property is blank, then how will I be able to retrieve the value of it? This is the code. I am not able to get the value entered in the component. I can't even find any getvalue method for it.
FacesContext facesContext = FacesContext.getCurrentInstance();
UIViewRoot root = facesContext.getViewRoot();
RichInputText inputText = (RichInputText) root.findComponent("it1");  // it1 is the id of the input text component
System.out.println("inputText: "+inputText);On using sop statement, this is the output which is getting generated, while I had entered 90.
inputText: RichInputText[UIXEditableFacesBeanImpl, id=it1]

One more thing. Once the VO is getting refreshed, I am able to display an inline message saying that 'Table refreshed Successfully!' (refer the code)
But in case if the user doesn't enter anything, and press TAB button, I want to display an error message exactly besides the input text component, saying that 'Please Enter an Integer.' According to my understanding, if the user enters a null value then while casting string to Integer, it will throw an exception, so I will be writing the code in the catch part. Any suggestions?
public void displayTable(ValueChangeEvent valueChangeEvent) {
        BindingContext bctx = BindingContext.getCurrent();
        BindingContainer bindings = bctx.getCurrentBindingsEntry();
        OperationBinding method = (OperationBinding)bindings.get("displayEmployeeTable");
        try {
            Integer getValue = Integer.valueOf(valueChangeEvent.getNewValue().toString());
            System.out.println("getValue: " + getValue);
            method.getParamsMap().put("deptId", getValue);
        } catch (Exception e) {
        method.execute();
        FacesMessage message = new FacesMessage("Table refreshed Successfully!");
        message.setSeverity(FacesMessage.SEVERITY_INFO);
        FacesContext fc = FacesContext.getCurrentInstance();
        fc.addMessage(null, message);
