Hey!

I need to read an array out of my request and generate a zk1 tree.

<treerow>
<treecell label="${each}" forEach="${cats}"/>
</treerow>

that doesn't work, because it just repeats the line with the treecell tag. How can i gerate elements with more than one line?

are there other loop types? like:
for (condition) {
<treerow>
<treecell label="${var}/>
</treerow>
}

thx

Use the zk "virtual" tag.

<zk forEach="${cats}">
<treerow>
<treecell label="${each}/>
</treerow>
</zk>

That doesn't work!

I get the exception:
com.potix.zk.ui.UiException: The zk element cannot be used other than as the root

my code:
<tree id="pages" width="150px" rows="15" style="border-color: white">

<treechildren>

<zk forEach="${requestScope.categories}">
<treeitem>
<treerow>
<treecell label="${each}"/>
</treerow>
</treeitem>
</zk>

</treechildren>
</tree>
