Combining EXTJS with WebObjects.

Hello,.. Well after almost giving up on my requirement to put more than one column in a wobrowser to have multiple selections.  I remind that before I did some little work with EXTJS. It has what we need. a GRID extjsComponent.. :D:D.. now how do I integrate WO and EXTJS?

In the example of grid they  are loading data from an array of arrays, and configuring "hard-coded" all the grid. How can I from the JS ask the WO server for the data to congifure the grid? is it possible?..
another approach I saw was to generate a hidden WORepetition and generate all the data, then form the JS get the element and create the grid, but this approach I don't like it, becuase if I need another grid somewhere else I have to do all again, I want to reuse code.

Another approach is to load the data form an xml, the same,  grid has a url: attribute I fetch the xml there, so in th backend I will need to generate the xml, keep it there, while EXTJS via the url: ask for it.. what comes to my mind are security stuff... and some theoretical stuff like:

How WO knows that the JS that its requesting  is valid for the session in the WO application?. 
I think this is about the request-n-response loop... isn't it?


So.. any advice... help, clue, light, code?

G.
