Pass an input value directly as action method argument

Is there a way to do pass an input value as a action's parameter without using managed properties?

i.e. 

<h:form>        
    <h:inputText id="input" />  
    <h:commandButton action="#{someBean.doSome(input)}" />  
</h:form>

Yes, it's during the form submit already there in the JSF component state. Just bind the input component to the view by binding attribute, which will reference an UIInput instance, which in turn has a getValue() method for the very purpose of retrieving the input value (so that you can pass it as action method argument):

<h:form>        
    <h:inputText ... binding="#{input}" />  
    <h:commandButton ... action="#{someBean.doSome(input.value)}" />  
</h:form>

The properness of this approach is however highly questionable and depends on concrete functional requirements. This approach is namely basically tight-coupling the view with the model and therefore considered a bad practice.
