You have to use the core methods.

First of all declare your core taglib by :

<?taglib uri="http://www.zkoss.org/dsp/web/core" prefix="c"?>

Then you can use the following :

@load(c:new1('java.lang.Boolean', 'true'))

Now ZK does autocasting of the Boolean so you can do just like this(without the whole core method's) :

@load(true)

Greetz chill.

Thanks for testing ZK 8. In general this should work when EL 3.0 support is enabled:

this issue is currently under investigation http://tracker.zkoss.org/browse/ZK-2808 please follow the status there.
