Hi everyone, I would like to use Form Binding for Validations and Status.dirty, but I'm having several problems with the Combobox and Hibernate.

This is the exception:

Exception Type: class org.zkoss.zk.ui.UiException
Exception: org.zkoss.zk.ui.UiException: I can't convert com.sarco.hibernate.MyClass@2896ac80 from class com.sarco.hibernate.MyClass to class com.sarco.hibernate.MyClass_$$_javassist_309 at [file:/E:/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/sarco/WEB-INF/pages/myfile.zul, line:54]

My Form:

<window apply="org.zkoss.bind.BindComposer" 
        viewModel="@id('vm') @init('com.sarco.AddEditMyClassVM')"
        border="normal" 
        width="500px"
        closable="true"
        mode="modal"
        onClose ="@command('closeWindow', event = event, status = fxStatus.dirty)"
        onCancel="@command('closeWindow', event = event, status = fxStatus.dirty)"
        form="@id('fx') @load(vm.selectedItem) @save(vm.selectedItem, before='save')">

And the combobox:

<combobox  model="@load(vm.items)" 
       selectedItem="@bind(fx.object)"
       value="@load(vm.selectedItem.value)"
       constraint="no empty">
<template name="model">
    <comboitem label="@load(each.value)" />
</template>
</combobox>

I get the exception when I select an item from the combobox.

Any ideas?
