           Summary: RExpression fails to convert arrayType(niltype)
           Product: Kepler
           Version: 1.x dev
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: actors
        AssignedTo: leinfelder at nceas.ucsb.edu
        ReportedBy: soong at nceas.ucsb.edu

Create a workflow with 2 RExpressions.  The first should output c(NA, NA).  The
second should take the output from the first as input.  Hook a Display to the
output of the second to observe the error in R.  Basically, a token of
arrayType(niltype) is sent, but the second RExpression doesn't know how to
convert this and drops the token.  I think it just needs another entry of "||
(token_type_string.startsWith("arrayType(niltype"))" around line 631 of
RExpression.java.
