Need help upgrading from 1.x to 2.x

Hi there,

I'm in the process of upgrading from Ext.Net 1.x to 2.x and need a little help regarding referencing Ext.Net controls in Javascript code. I want to pass the value of some entry fields as parameters to an Ajax Proxy. I used to do the following (dfVon and dfBis are the IDs of two DateFields):

<ext:AjaxProxy Json="true" Url="http://Someserver/SomeService.svc/SomeFunction">
    <ActionMethods Read="GET" />
    <Reader>
        <ext:JsonReader />
    </Reader>
    <ExtraParams>
        <ext:Parameter Name="machine" Value="PM1" Mode="Value" />
        <ext:Parameter Name="startDate" Value="#{dfVon}.getValue()" Mode="Raw" />
        <ext:Parameter Name="endDate" Value="#{dfBis}.getValue()" Mode="Raw" />
    </ExtraParams>
</ext:AjaxProxy>

But using Ext.Net 2.x, this results in the following error:

Uncaught TypeError: Cannot call method 'getValue' of undefined

What is now the correct way to do this in 2.x?

Thanks in advance!

Follow up: I've just noticed that the placeholders, #{dfVon} for example, are now replaced with App.dfVon in the code sent to the browser. What's that App thing?
