.setValue of an Element/Hidden Element

Question

function change(e){
var app = UiApp.getActiveApplication();  
app.getElementById("date").setValue(e.parameter.picker);  
Browser.msgBox(e.parameter.date+"|"+e.parameter.picker);  
return app;  
}

I've spent the last hour or so trying to figure out what I am doing wrong, but, the .setValue() seems to not be working, since the Browser.msgBox displays: " | August 8, 2012 0:00:00 (MST)" even though both sides from the | should display the same thing.

The right way to assign a value to a widget in a handler function in GAS is simply (just as you did in your question) like this :

app.getElementById("date").setValue(e.parameter.picker)

but what follows in your code can't work because value is passed to the e.parameter when the handler function is called , not during execution of the handler. This means that e is not updated inside the handler function but it will be on the next call.
