[Dev-luatex] Question on node.insert_before()

[Patrick Gundlach]

Hi,

this gives me an error:


----------------------------------------
\directlua{
  local second=node.new("rule")

  local v=node.vpack(second)

  local first=node.new("rule")

  node.insert_before(v,second,first)
}

\bye
----------------------------------------

Attempt to node.insert_before() a non-existing node

I assumed that node.insert_before would put the first node before the second node and "corrects" the list pointer of v.

Q: why do I get the error?
