Msg must be displayed when mismatch occurs

Question

Hi.,
I am using jdev 11.1.1.5
I had created Glhd,GLln EO's with corresponding VO's
I had also created an transient attribute in GLln listed below
Debitamt object.getRowset.sum("GLln.GjlDebitAmt")
creditamt object.getRowset.sum("GLln.GjlCreditAmt")
I had also created a viewlink
Glhd.bu = GLln.bu
I had dragged and dropped GLhd as adf:Forms GlLn as adf:table
My Scenario:
I need to display a msg if there is an mismatch in the values of Debitamt and creditamt

Answer 1

one suggestion is to create a before phase Listener and display the message in the before render phase.
in your pagem select the view node from the structure window, select BeforePhase attribute and create your own method
    public void beforeRender(PhaseEvent phaseEvent) {
        // check your condition, if true show the message
        int RENDER_RESPONSE = PhaseId.RENDER_RESPONSE.getOrdinal();
        if (phaseEvent.getPhaseId().getOrdinal()== RENDER_RESPONSE) {
            String messageText = "Add your message text";
            FacesMessage fm = new FacesMessage(messageText);
            fm.setSeverity(FacesMessage.SEVERITY_INFO);
            FacesContext context = FacesContext.getCurrentInstance();
            context.addMessage(null, fm);
