Maybe you could use the if (or the visible attribute)?

<cell>
    <label value="@load(each.prop)" if="@load(not each.withLink)"/>
    <a href="..." if="@load(each.withLink)">
        <label value="@load(each.prop)" />
    </a>
</cell>

So the each should give a boolean back with the property "withLink".

Edit :

After reading your 2 comments :

1) You don't have to use each.withLink, but I don't see the difference between ="@load(each.test() ? 'X' : 'Y')" or use the visible attribute.

2) The if can work but indeed you don't have to use @load but :

<label value="@load(each.prop)" if="${not each.withLink}"/>

3) Other (proper) solution :

Create a Taglib (here I call it 'mine-taglib.tld')

<taglib>
    <function>
        <name>instanceXX</name>
        <function-class>be.chillworld.utils.ZkUtils</function-class>
        <function-signature>
            java.lang.Boolean checkInstanceXX(java.lang.Object)
        </function-signature>
        <description>Checks for a specific instance</description>
    </function>
</taglib>

Create java class :

public class ZkUtils {
    public static Boolean checkInstanceXX(Object o) {
        return (o instanceof AtomicInteger);
    }
}

Zul :

<?taglib uri="/WEB-INF/tld/mine-taglib.tld" prefix="mt"?>
.....
<cell>
    <label value="@load(each.prop)" visible="@load(not mt:checkInstanceXX(each))"/>
    <a href="..." visible="@load(not mt:checkInstanceXX(each))">
        <label value="@load(each.prop)" />
    </a>
</cell>

Hello aznavour,

In order to accomplish your task you have to implement a custom rowRenderer as shown in the link bellow:

http://www.zkoss.org/zkdemo/grid/dynamic_renderer

In detail, you set in your zul script a rowRenderer which targets a implementation of the RowRenderer class.

There you can set the components you wish for each row.

Best Regards,
