Webflow RequestContextHolder Returns Null RequestContext

I need to run an AJAX method from one of the pages in my webflow. According to the docs, this is what RequestContextHolder is for.

So, here is my method:

@RequestMapping(value="training/test", method=RequestMethod.POST)
public GridItem getGridItems() {

    RequestContext requestContext = RequestContextHolder.getRequestContext();
    Set<String> fsKeyset = requestContext.getFlowScope().asMap().keySet();
    for (String key: fsKeyset) {
        log.debug(key);
    }
    Form form = (Form) requestContext.getFlowScope().get("form");

    return form.getGridItem();

}

Unfortunately, the RequestContext is null. Is there something special I need to do to actually GET the RequestContext?

Lets say your flow/view definition look like this

<view id="someId" view="someView" model="entity">

<transition on="ajaxSave" to="handleAjaxActionState"/>
<transition on="save" to="handleStandardSave"/>
</view>

then the bare min for your ajax url would look like: 

url=${flowExecutionUrl}&_eventId=ajaxSave&ajaxSource=true

executing this (while you are still inside "someId" view state) will then get picked up in the "ajaxSave" transition.

disclaimer: I did not test the above example.
