Cannot retrieve node with :: in label name?

[kuzeko]

I have a node with some label that contains ::

But when I run

gts.V().hasLabel("home::simple").count().next();

it returns 0.

Is this a known issue?

Thanks

In Cypher you can do: `home::simple` When the label contains spaces or special chars. Unsure if it works in tinkerpop, but you can try: gts.V().hasLabel("`home::simple`").count().next(); Luke Daugherty From: M.

Tried that, does not work

I'd guess that has something to do with how TinkerPop tried to handle multi-label support :/

https://tinkerpop.apache.org/docs/current/reference/#_multi_label

[kuzeko]

I don't get it ... ?

[spmallette]

I just meant that TinkerPop uses the double colon for special meaning with multi-label support for neo4j. Perhaps it is interfering with your label that happens to have a double colon. Perhaps that is why your query does not work.

[kuzeko]

uh, that is unexpected

[spmallette]

I think I was able to confirm that this is an issue in TinkerPop and related to the special double colon usage I described in previous comments. Labels that have that delimiter added with addV() end up being split automatically. Making the delimiter configurable is an option but given the way things are implemented I think that ends up being "hard" for various reasons. If this issue is of continued concern perhaps it would be best to create an issue in TinkerPop:

Ok, I've tried to open the issue.
