User Story

As a ZK MVVM user, I want to know how to solve the upgrade issue when I use ZK 10 client MVVM

Case1: @WireVariable is MVC
zephyr-master/zephyr-test/src/main/webapp/mvvm/book/advance/wirevariables/WireFromImplicitObject.zul

Case2: drag not work (Shall find another way to do the drag)
zephyr-master/zephyr-test/src/main/webapp/mvvm/book/basic/component-switch.zul

Case3: @ContextParam(ContextType.COMPONENT), it is not supported
zephyr-master/zephyr-test/src/main/webapp/mvvm/book/basic/contextparam.zul

B86-ZK-4255.zul

Case6: @SelectorParam 

Note: should support if the selector can locate to server side component.
B95-ZK-4722.zul (Should work, div is a ViewModel owner)

Case7: @Listen

Case8: @Wire

Case11: Type issue
B01059DifferentType.zul

Case17: converter to case Object type issue

zephyr-test/mvvm/issue/F00743_1.zul

public Object coerceToUi(Object val, Component component, BindContext ctx) {
   return sort((Set)val); <-- no way to detect the Set type here, we can only support Set in method parameter type, but still Set<Item> cannot support as well.
} 

Case18: itemRenderer="@load(vm.itemRenderer)" (suggested to use <template>)

test2/B85-ZK-3733.zul

case19: Cannot access selectedItems from Event (onXXX="..." should be @command)

mvvm/issue/B00762Listbox1.zul

case20: sorting feature - https://tracker.zkoss.org/browse/ZK-5318
Unable to support sorting function at Server side, so we decide not to support this at Client MVVM. 
test2/F96-ZK-4595.zul
 case21: ProxyTargetHandler - https://tracker.zkoss.org/browse/ZK-5322

Unable to support ProxyTargetHandler for Client MVVM

case22: Unable to support getSaveFormFieldNames() from a binder passed through @ContextParam(ContextType.BINDER)
-> binder.getSaveFormFieldNames(myform);
in B95_ZK_4685VM.java
 

case 23: ZK-3952
public void scrollToIndex(int index) {ListModel<Object> model = getModel();
B00762Combobox1.zul, try to access model in component

F00743_2.zul
getModel shouldn't be called in ClientMVVM.

B86-ZK-4295.zul
B85-ZK-3932.zul
case 25: render client object in include component

case 26: cannot support FormLegacy in ViewModel.

test2/F95-ZK-4501.zul

case 27: setSelectionControl on ListModel - ZK-5407

case 28: getter method should be pure getter
ex. https://github.com/zkoss/zk/blob/6db8ccad0efc7345594a5a96d9c0f0cb9054e352/zephyr-test/src/main/java/org/zkoss/zktest/test2/B65_ZK_2409VM.java#L27-L33

case 29: Custom Binder by using AnnotateBinder

mvvm/issue/B00632.zul

case 30: Cannot support viewModel="@id('vm') @init(module)" from outside this page scope. (see ZK-5405)

zephyr-test/mvvm/book/basic/modulize.zul with modulize-moudle1.zul

case 31: Not support Fragment component for Client MVVM (see ZK-5340)

Acceptance Criteria

System log when server startup and the check should be pluggable
