Inputfield dependencies with PageTable?

[suntrop]

I am wondering if it is possible to hide a field depending on the PageTable field. 

I would like to hide a field when the PageTable has any child-pages saved (or show only, if there are no pages saved). But I couldn't figure out how or if it is supported at all. 

product_variations.count!=0  // … hides it in any case
product_variations=''  // … hides it in any case

The custom PHP option in @Robin S' module (http://modules.processwire.com/modules/custom-inputfield-dependencies/) should make this possible.

That would be my next choice  Thought it may be possible by core. I'll have a look at it.
