How can I dynamically add an attribute to a body element in a GSP page
Question
In Grails 2.3.7, is there a way to use an expression in a GSP page to add an attribute to a body element? In the code below, the expression in the p element works, but the same expression in the body element causes a error: Expecting '=' after attribute name (${raw('this="that"')}).
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body ${raw('this="that"')}>
<p ${raw('this="that"')}>Hello!</p>
</body>
</html>
I'm trying to do this in a layout and pick up the corresponding attribute from the original page with pageProperty , but the same error occurs on the body element in the page layout as well.
Replacing an attribute value does work in a body element like this:
<body this="${that}">
but this won't work because I do not want the attribute to appear at all if it has no value.

the problem is, that the body tag is replaced by the <g:layoutBody /> tag and therefore could not be set like this.
One solution is to use to set different stuff in the sitemesh layout. An example of this is shown here :
<html>
<head>
<g:layoutHead/>
</head>
<body class="${pageProperty( name:'body.class' )}">
<g:layoutBody/>
</body>
</html>
