Daniel Kuppitz commented on TINKERPOP3-549:
-------------------------------------------
The last traversal is still an issue:
{code:none}
gremlin>
g.V(1).repeat(out().as("a")).until(label().is("software")).in("created").back("a").path().by(branch{it.get().getClass()}.
gremlin> option(ArrayList.class, unfold().values("name").fold()).
gremlin> option(none, values("name")))
==>[[], lop, marko, lop]
==>[marko, lop, josh, lop]
==>[marko, lop, peter, lop]
==>[marko, josh, ripple, josh, [josh, ripple]]
==>[marko, josh, lop, marko, [josh, lop]]
==>[marko, josh, lop, josh, [josh, lop]]
==>[marko, josh, lop, peter, [josh, lop]]
{code}
This is the expected result:
{code:none}
gremlin>
g.V(1).repeat(out().as("a")).until(out().count().is(0l)).in("created").back("a").path().by
{it instanceof ArrayList ? it*.value("name") : it.value("name")}
==>[marko, lop, marko, lop]
==>[marko, lop, josh, lop]
==>[marko, lop, peter, lop]
==>[marko, josh, ripple, josh, [josh, ripple]]
==>[marko, josh, lop, marko, [josh, lop]]
==>[marko, josh, lop, josh, [josh, lop]]
