You can write your own concat method in your class.. Then use it like this:

value="@bind(vm.concat(vm.order.firstName,' ',vm.order.lastName))" 


public String concat(String... a)
{
    String returnString="";
    for(int i=0;i<a.length;i++)
    {
        returnString=returnString+a[i];
    }
    return returnString;
}

(For info and improving your skills, it's not critic cause your code is good) You can yes but if I wrote your code I should do this : first @load in stead of @bind. Second use an for each, yes that works also on arrays, thirth use Stringbuilder, what is a lot more efficient than returnString=returnString+a[i] fourth if you want to implement varargs what is good, write a method for 1 - 2 (and 3) Strings and for the x strings that you will use the most. This is also more effecient then the varargs.

You will have to use el expressions.

Now I don't think you need to @save the element so do just an @load.
@bind() = @load() @save()

<?taglib uri="http://www.zkoss.org/dsp/web/core" prefix="c"?>
<label value="@load(c:cat3('/img/32/number',each.slotNumber,'blue32.png'))"/>
