Cronedit in rails

When I tried to integrate the cronedit gem with the rails2.1 application
it is not working. The pages becomes blank. I think it is not getting
work.
I tried the following things.

./script/console

I added some cron entries. It is updating properly.

But rails application(On apache) persay it is not working.

In web-brick it is working properly…

Any help…
