Embedding JavaScript rendered controls into a BSP page

Hello,

I want to add a JavaScript rendered grid control from the Ext JS framework into a tab of a BSP application.

It looks however that the layout management code behind BSP (it has to manage its tab container somehow)

interferes with the JavaScript of the Ext JS library.

My question is how to embed such a non-trivial JavaScript software into a BSP page without interfereing with the internals of the BSP rendering engine.
