@erictgrubaugh it looks like the original programmer wanted to disable sublist columns during pageInit. I'll just omit the pageInit reference to lineInit and let all the lineInit code happen during its own entry point.

I have used this approach, when you want the columns on the new line to be disabled. When the form is loaded by the system and the focus goes to the new line, it does not trigger the line init function. That was how it was in the past, not sure if that has changed now.
