Hi

I will have a better feel for the performance after I get a little further into my project. However, the only time delay that I have experienced so far is the initial load time after that everything so far happens very quickly. I have opted for a VFP technique of only loading controls when the form or tab page is activated. I don't know if I needed to do this but I got so use to doing it in VFP that I just carried it over to QooxDoo figuring it could not hurt.

The area of tweaking for me has been in the data binding area. They have a relatively simple but powerful method of data binding but I wanted to make it more automatic so I have built this into my base classes so it just happens after I assign the equivalent of a "ControlSource". I also am now building support for parent child relationships so that when I change the selection in the parent list all the child items get refreshed as well.

>>QooxDoo is turning out to be quite understandable ... So I have built similar data binding in QooxDoo so it is simply a matter of specifying a JSON Store (similar to a VFP table) and a column name (similar to a VFP field) and the framework takes care of loading and saving the values.
