How to disable the 'Next' button of a combo container

Hi,

I want to disable the 'Next' button of a Combo container. I am using the combo container and I have two jsps and in 1st jsp there is a checkbox, on click of that new jsp will be invoked in that jsp I have to disable the 'Next' button of a container and again after fetching the values it should come back to the previous page and the next button should be enabled again.
