Hello,here is a weird situation, and guess i have tried everything what i think should have worked.

look below the code first ,in this i have taken a groupbox and a div in vlayout,In div their is a include component,I want to pass the present viewModel object(vm) to the viewmodel of this included page.

    <window mode="modal" popup="true" width="1000px" height="635px"
        closable="true" 
        apply="org.zkoss.bind.BindComposer" border="normal"
        position="center,top"
        viewModel="@id('vm') @init('xxx.ViewModel')">
        <vlayout>
            <groupbox width="100%" mold="3d" height="280px"
                closable="false">
                <caption>
                ............
            </groupbox>
            <div>
                <include   src="@bind(vm.path)"
                    viewModelArg="@load(vm)">
                </include>
            </div>
        </vlayout>


    </window>
</zk>

included page viewmodel code:

   @AfterCompose
    public void afterCompose(@ExecutionParam("viewModelArg") ViewModel viewModel  ){}

initially somehow it was working ,but as i have changed some code inside my project(don't have any idea about the change,but its not relative as much i know to this code),Now it has stopped working.and gives a null value to viewModel.

The situation is that ,we can have only string type value and for non string-typed their is no clear documentation about how to retrieve the value in included page viewmodel.I get a NULL everytime. Thanks in advance.
