Hi,

Sorry for late reply.

Without this guard, soap4r will generate something like

  <epointment xsi:type="xsd:string">
    <ivars>
      <ical_params>blah blah</ical_params>
    </ivars>
  </epointment>

instead of

  <epointment xsi:type="xsd:string">epointment#1481</epointment>

which should not be what you want.

Hmm.  Can soap4r distinguish objects

  class Foo
    attr_reader :ical_params
  end
  obj = Foo.new
  obj.ical_params = 123
  obj (ical_params in obj should be serialized)

and

  obj = "abc"
  obj.instance_eval { @ical_params = 123 }
  obj (ical_params in obj may not need to be serialized)

?
