Flash message contents lost in layout

275 Views Asked by nIx.. At 04 April 2025 at 22:12

This is the scenario:
I have layout : main.gsp
and have a page on which this layout is applied: homepage.gsp
I have a div in main.gsp where I display flash message if any.

Now,
when controller sends any flash message, its available in homepage.gsp but when layout is applied on it and page is displayed, flash message is lost.

I want flash message to be available in layout code. Again, it would be preferable if I need not add any code to homepage.gsp as there are many such pages where controller can return flash message.

How do I handle this?
Any help much appreciated.

This is the code I will used, I have tested and it work. main.gsp

    <body>
    <div id="grailsLogo" role="banner"><a href="http://grails.org"><img src="${resource(dir: 'images', file: 'grails_logo.png')}" alt="Grails"/></a></div>
    <div>
        <g:if test="${flash.message }">
        ${flash.message }
        </g:if>
    </div>
    <g:layoutBody/>
    <div class="footer" role="contentinfo"></div>
    <div id="spinner" class="spinner" style="display:none;"><g:message code="spinner.alt" default="Loading&hellip;"/></div>
    <r:layoutResources />
</body>

Controller:

    package com.mtsinai

class EmployeeController {

    def index() { 
        flash.message = 'Welcome world'
    }
}

index.gsp

    <%@ page contentType="text/html;charset=UTF-8" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<meta name="layout" content="main"/>
<title>Insert title here</title>
</head>
<body>
  <div class="body">

  </div>
</body>
</html>

Note that the flash message will be displayed on top of the body or the page that will be rendered
