Marshal.dump fails

[sl1974]

Marshal.dump fails when applied to Calendar objects with error can't dump hash with default proc (TypeError).

Here is an example that fails with the mentioned error:

require 'icalendar'

# Create a calendar with an event (standard method)
cal = Icalendar::Calendar.new
cal.event do |e|
  e.dtstart     = Icalendar::Values::Date.new('20050428')
  e.dtend       = Icalendar::Values::Date.new('20050429')
  e.summary     = "Meeting with the man."
  e.description = "Have a long lunch meeting and decide nothing..."
  e.ip_class    = "PRIVATE"
end

Marshal.dump(cal)

Marshalling worked fine with v. 1.5.

We have no plans to support Marshal.dump on iCalendar objects.

As an alternative, you can just use cal.to_ical to get a string representation that can completely rebuild your object structure with Icalendar.parse (or the Icalendar::Parser class for more tricky cases)
