Ha, at some point I did add the special case code to handle string array, but never removed the dbr type check.

f9c1489fcc24c97d36e1edd85e94c1261383282a turns on string array mapping.

In [1]: from p4p.client.thread import Context

In [2]: C=Context('pva')

In [3]: C.get('arrs')
Out[3]: []

In [4]: C.put('arrs', ['hello', 'world'])

In [5]: C.get('arrs')
Out[5]: [u'hello', u'world']

Using an IOC w/ QSRV and

record(waveform, "arrs") {
  field(FTVL, "STRING")
  field(NELM, "10")
}

@mrkraimer Can you update and repeat your test to confirm?
