After configuring the "store client ID in JavaScript variable" it's fairly easy to retrieve a control's value with the following:

var test = NWF$("#" + someID + " option:selected").text();

However, if this control is a List Lookup, I am only able to retrieve these values via an onClick event in the page (or after waiting for a few seconds with a timer). Even after waiting until the NWF.FormFiller.Events have completed and the DOM has loaded, these fields are still "Loading..."

Is there another Nintex function I can monitor in order to make my function call once it completes?
