Accessing ADF UI components programmatically

Question

How can I locate an ADF UI component by its ID and get access to it programmatically, without using the Binding property?
What's wrong with the following code?
public void onButtonPressed(ActionEvent actionEvent) {
FacesContext fc = FacesContext.getCurrentInstance();
ELContext elctx = fc.getELContext();
ExpressionFactory ef = fc.getApplication().getExpressionFactory();
ValueExpression ve = ef.createValueExpression(elctx, "#{it1}", UIXComponent.class);
RichInputText it = (RichInputText)ve.getValue(elctx);
System.out.println(it.getAttributes().get("label"));
it.setValue("hehe");
"it1" is the Id of my InputText.

Hi Alex,
That is not the right way to get the component, #{it1} is not valid.
Here is the sample code to get the component by id, but is not recommended as you should know the parent component ids as well and it would be difficult to maintain in long run:
        FacesContext context = FacesContext.getCurrentInstance();
        context.getViewRoot().findComponent("<id>")What is your exact usecase?
Any specific reason for not using binding property?
