the following code causes an NPE when clicking the button after session serialization (e.g. server restart)
<zk xmlns:w="client"> <div apply="org.zkoss.bind.BindComposer" someVariable="@ref('peter')"> <apply param1="@load(someVariable)"> <label value="@init(param1)"/> </apply> <button onClick="@command('') label="click me""/> </div> </zk>
