I'm getting the following exception when using the g:layoutTitle tag after upgrading my app to 2.4.4
Caused by: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'com.opensymphony.sitemesh.compatability.Content2HTMLPage@21b3cfb7' with class 'com.opensymphony.sitemesh.compatability.Content2HTMLPage' to class 'com.opensymphony.module.sitemesh.parser.AbstractHTMLPage'
I've tried with even just hardcoding a string as the default value, like this:
<title><g:layoutTitle default="Test"/></title>
And I still get the issue. Did I miss something when upgrading? I'm not sure what the issue is here.
I also get the same issue when using pageProperty. Ex:
<body class="${pageProperty(name: 'body.class')} ${pageProperty(name: 'page.sectionName')}">
That throws the same exception, but also works when using Grails 2.3.6.
I was experiencing this same issue after upgrading from Grails 2.2.5 to 2.4.4. Changing/adding this line in Config.groovy solved it for me:
Hope this helps someone - I was stumped for a couple days on this one.
