This tries to call all the elements of the array...

but if grid is false, callfunctions[1] will not be a function.

The same could also happen with callfunctions[2] depending on the
outcome of all these tests.

This is odd.  There's no point in setting callfunctions[4]=nodeDraw of
you are going to assign a different value immediately afterwards.
