Hi,
I want to show a simple tree:
<%@ taglib prefix="z" uri="http://www.zkoss.org/jsp/zul" %>
<z:page zscriptLanguage="java">
<z:zscript>
SimpleTreeNode stn1 = new SimpleTreeNode("C1", new ArrayList());
SimpleTreeNode stn2 = new SimpleTreeNode("C2", new ArrayList());
ArrayList al = new ArrayList();
al.add(stn1);
al.add(stn2);
SimpleTreeNode root = new SimpleTreeNode("ROOT", al);
SimpleTreeModel stm = new SimpleTreeModel(root);
</z:zscript>
<z:vbox>
<z:tree model="${stm}" id="tree" pageSize="5"/>
</z:vbox>
</z:page>
When I run the application the following exception is thrown:
java.lang.InstantiationException: org.zkoss.zul.TreeModel at java.lang.Class.newInstance0(Class.java:340) at java.lang.Class.newInstance(Class.java:308) at

No idea. Could anyone help? Thanks in advance.
My ZK version is: 3.5.2 with jsptags 1.2.0.
@AllenFox
Hi allen, i had tried your code, but i can't have the same result like yours. So i modified some codes to make sure it'll work well,
just please compare these codes to yours.
<z:page zscriptLanguage="java">
<z:zscript>
List empty = new ArrayList();
SimpleTreeNode stn1 = new SimpleTreeNode("C1", empty);
SimpleTreeNode stn2 = new SimpleTreeNode("C2", empty);
List aList = new ArrayList();
aList.add(stn1);
aList.add(stn2);
SimpleTreeNode root = new SimpleTreeNode("Root", aList);
SimpleTreeModel stm = new SimpleTreeModel(root);
</z:zscript>
<z:vbox>
<z:tree model="${stm}" id="tree" pageSize="5"/>

@AllenFox
There is another idea, maybe you can upgrate your library to zk 3.6.3 and try it again.
It's really a strange exception...
/Joy
Hmmm, upgrading to ZK 3.6.3 and to jsptags 1.3.0 gives slightly different exception. Seems like data binding doesn't work.

"java.lang.NoSuchMethodException: No contructor compatible with [java.lang.String] in org.zkoss.zul.TreeModel"
Seems you put a String into TreeModel's constructor?
Try to use <![CDATA[ ... ]]> to include all your codes in zscript, but i will suggest you use GenericForwardComposer
instead to use databinding.
We suggest developers use more GenericForwardComposer, it can control each component or page better than other ways.
If you need some reference, please start at here.
