Ext.data.ScriptTagProxy and Domino JSON

[kerocs]

I'm building an apllication on ext 3.0 which will pull data from my notes server.
Since this is cross domain and I will be filling grids I have to use the Ext.data.ScriptTagProxy.
According to the API I will need a callback function which is not provided by a notesview json url : ?ReadViewEntries&OutputFormat=JSON

Is there any quick way to add this callback function, basically 'stcCallback1001()' to the output given by the notes server.

An agent, a page or a form doing something like

"stcCallback1001(" + myviewurl?ReadViewEntries&OutputFormat=JSON + ")"

Thanks for thinking with me, Johan
