how to use smart rendering with jboss 5.1/java/struts 1.2

I have been trying for the last two weeks on trying to get the smart rendering feature for dhtmlxGrid to work with my environment which includes jboss 5.1/java/struts 1.2.

I have imported the appropriate javascript and enable the smart rendering feature after the init just like all the examples in the documentation, but I cannot get the event to fire as I scroll down in the grid. I have tried a very simplified version of the grid, stripped out all other features, but it still is not firing the event. I am trying to get it to fire into my action class which I could then call my search routine and build the XML appropriately to send back.

Any help is appreciated.

Thanks,

CODE:
Please note that this code was in a custom designed tag so there are a few variables such as system time, that are dynamically generated in order to have many grids on 1 page each with their own unique name.

//custom changes made to the look & feel of stylesheet.

//custom functions needed for special formatting & sorting.
