Hi tisaksen,

You can, but you need to import your enum in zul first

<?import foo.bar.MyEnum?>
<zk>
...
<textbox...

Hi tisaksen,

This is working on my side: zul:

    <?import foo.bar.MyEnum?>`
    <zk>
        <div viewModel="@id('vm')@init('foo.bar.EnumVm')">
            <button onClick="@command('myCommand', tag=MyEnum.MONDAY)" />
        </div>
    </zk>

EnunVm.java: public class EnumVm {

    @Command("myCommand")
    public void myCommand(@BindingParam("tag") MyEnum tag) {
        System.out.println(tag);
    }

}

If the <?import ?> processing instruction doesn't work, you can also import from zscript, or from a global import http://zkfiddle.org/sample/8p1lrf/1-mvvm-and-enum#source-1

You mentioned Enum cannot be instantiated using reflection, could you post a stacktrace or a code sample where you run in that limitation?
