Hi, I need some help please...

I have a custom datatype that renders uses the checkbox list and has its root node id defined so that it only shows that node's children as options.   This works great but when I package the site and install it elsewhere it is still looking for the same root node id, which does not exists because the imported content now as different ids.

How can I get the package to set the root node id correctly on install so that the checkbox list works?

thanks

Chris
