Passing array argument results in java class cast exception

[gching]

I am probably doing something wrong here but just wanted to post it here if it is an actual error.

I am passing an array of strings over to be used as an argument for the .out() transform function. Specifically, my code is the following:

var point_of_traverse_vertice = query.var(g.V('name', point_of_traverse_id).next())
query(point_of_traverse_vertice.out(['edge_label_1', 'edge_label_2']))

This will result in an error with the following stacktrace:

 Error: javax.script.ScriptException: java.lang.ClassCastException: [Ljava.lang.String; cannot be cast to java.util.List
      at RexsterClient.<anonymous> (/Users/gching/Projects/app-builder/api/node_modules/grex/src/rexsterclient.js:117:34)
      at IncomingMessage.EventEmitter.emit (events.js:117:20)
      at _stream_readable.js:910:16
      at process._tickCallback (node.js:415:13)

Trying to debug it personally, the script being sent over is:

/graphs/graph/tp/gremlin?script=i0%3Dg.V('name'%2C'id').next()%0Ag.V('name'%id').next().out(%5B'edge_label_1'%2C'edge_label_2'%5D)%0A&rexster.showTypes=true&

The thing to note is that %5B and %5D is present, which represents the [ and ] respectively. I am assuming that is being parsed through ArrayArgument rather than the Argument helper class. I don't know much about the code base and have just recently started using grex so I might be making wrong assumptions; do tell me if I am.

Thanks for the help!
