c# - Caliburn.Micro No target found for method -

i'm using caliburn.micro wp7 project , maintain getting unusual error of pages. can't reproduce myself appears in bugsense logs. how utilize it. xaml:

cal:message.attach="[event loaded] = [action init()]"

and in viewmodel:

public async task init() {...}

or on other pages just

public void init() {...}

this stacktrace bugsense:

0 system.exception: no target found method init. 1 @ caliburn.micro.actionmessage.invoke(object eventargs) 2 @ system.windows.interactivity.triggeraction.callinvoke(object parameter) 3 @ system.windows.interactivity.triggerbase.invokeactions(object parameter) 4 @ system.windows.interactivity.eventtriggerbase.onevent(eventargs eventargs) 5 @ system.windows.interactivity.eventtriggerbase.oneventimpl(object sender, eventargs eventargs) 6 @ ms.internal.coreinvokehandler.invokeeventhandler(int32 typeindex, delegate handlerdelegate, object sender, object args) 7 @ ms.internal.jolthelper.fireevent(intptr unmanagedobj, intptr unmanagedobjargs, int32 argstypeindex, int32 actualargstypeindex, string eventname)

any ideas on how can determine what's wrong?
