Tabbar into Layout

Hi;

I have a 3L Layout:

1 Cell (“a”): Have a single form with a button. When I click the button, run a function that attach a grid into cell (“b”).

2 Cell (“b”): Have a grid with links. When I click this link, run a function that attach a tree into cell (“c”). Detach object from cell (“b”) and attach a Tabbar into cell (“b”).

3 Cell (“c”): When I click an option from the tree, run a function that add a tab into Tabbar in cell (“b”).

Without problems but If I click the button from the form again, and click the link from the grid, apear an error:
No se puede obtener valor de la propiedad ‘className’: el objeto es nulo o está sin definir
in dhtmlxtabbar.js

Can you help me?
