Pass the error Message to XPage client from Java Server code

Here is my Java code, before call I call the save() method. I want to check this business rule.

   if (endDate.before(startDate)){
        message = new FacesMessage(FacesMessage.SEVERITY_ERROR, "",
        "The end date should be not before the start date.");
        // Throw exception so that it prevents document from being saved
        FacesContext facesContext = FacesContext.getCurrentInstance();
        facesContext.addMessage("travel_endDate",message);
        return false;

    }

I want this message display at the "travel_endDate" component.

You have to use the client id of your component when adding the message.

1.) Add a binding to you component

<xp:inputText
    id="travel_endDate"
    binding="#{errorComponent}">
</xp:inputText>

2.) resolve the variable in your save method

UIComponent cmp = (UIComponent) facesContext.getApplication().getVariableResolver().resolveVariable(facesContext, "errorComponent");
String clientId = cmp.getClientId(facesContext);

3.) Add the message with the id to the facesContext

facesContext.addMessage(clientId,message);
