Conditional class for body
I've run in to a situation where the CSS class used for the body of my
layout.tml varies depending on certain conditions. I've tried using
variously:
<body t:class=<t:if test="xyzTest" negate="true">'xyzClass'</t:if>>
Or:
<t:if test=" xyzTest ">
<body class="'xyzClass'">
<p:else>
<body>
</ p:else>
</t:if>
. and several other permutations without success - I am getting variations
on parse errors with the general theme that class parameters cannot contain
quotes, or that body tag must be accompanied by closing body tag etc.
Can anyone suggest a working approach to this simple use case? It's
important to be able to have the CSS class explicitly in the tml, and not
buried in a java property.
Thanks,
Jim.

Hi Jim,
You can give an id to body and then use JavaScript.
<script>
<t:if text="xyz">
$('body').addClassName('myClass');
<p:else>
$('body').addClassName('otherClass');
</ p:else>
</t:if>
</script>
But I think the Michael's solution very good too.

Thiago, Pablo,
Thanks for the replies. I'll try one of those methods.
Regards,
Jim.

Just make your Java method look for the class name in some appropriate
place (properties file, etc).

Thanks for the quick response Michael. The reason the CSS class name needs
to be present in the tml is that I am not in control of the CSS / overall
look of the app, and some of the CSS / front-end people may not necessarily
know where to look within the java code. I guess if no other solutions are
apparent I can use the property approach.
Regards,
Jim.

Hi Jim,
I've used class="${xyzClass}" before in the past. Then implemented
getXyzClass() in my .java. You said it was important to not be in the
Java for you and had to be in the TML? Why is it that important when
both would require a WAR redeploy in a real production environment?
