Unable to throw 'Error: A value is required' on a field from bean

Question

Scenario: I have an input text field and a button on a page. The input text is not required initially. I want this to be set to required after the button is clicked. So, I am doing this on the action listener of the button and returning to the page. This just returns to the page but does not throw the required error. The error is thrown the second time I click on the button(No listeners are called this time as the required property is already set). I want the error message to display immediately after clicking the button, the first time(after returning from the bean).
Options Tried:
I used the following in the action listener of the bean
setValueMandatory(true); //Used this as a binding value for the required property on the input field
textValue.setValid(false); //textValue is my input text's binding to the bean
textValue.validate(facesContext);
textValue.processUpdates(facesContext);
textValue.processValidators(facesContext);
AdfFacesContext.getCurrentInstance().addPartialTarget(textValue);
FacesContext.getCurrentInstance().renderResponse();
I am able to focus on the field using the cursor but unable to throw the message. Clearly, some form submit or an action need to occur on the page to render the response(or, repaint the page programmatically). But, how do I do this from the bean?

Divya,
Have you tried passing the Component instead of null in my previous code?
here is the sample i tried and it works fine.
jspx code snippet
    <af:inputText label="Label 1" id="it1" binding="#{pageFlowScope.attributeValuesBean.rtx}"/>
    <af:commandButton text="commandButton 1" id="cb1"
                                  actionListener="#{pageFlowScope.attributeValuesBean.throwMessage}"/>backing bean snippet
    private RichInputText rtx; // add getter and setter
    public void throwMessage(ActionEvent actionEvent) {
        // Add event code here...
           FacesMessage fms = new FacesMessage("A value is required");
            fms.setSeverity(FacesMessage.SEVERITY_ERROR);
            FacesContext ctx = FacesContext.getCurrentInstance();
            ctx.addMessage(getRtx().getClientId(), fms);
