I have the following types, in effect four nested std::vector types

    namespace ndlcom_device_driver
    {
         struct ConfigureRegisterBit {
             std::string name;
             int bit;
             bool value;t
         };

         typedef std::vector< ConfigureRegisterBit > ConfigureRegisterBits;

         struct ConfigureRegister {
             std::string name;
             representations::RegisterId id;
             double value;
             ConfigureRegisterBits bits;
             std::string valueString;
         };

         typedef std::vector< ConfigureRegister > ConfigureRegisters;

         struct DeviceClassRegister {
             std::string deviceclass;
             ConfigureRegisters registers;
         };

         typedef std::vector< DeviceClassRegister > DeviceClassRegisters;

         struct JointConfig {
             std::string jointName;
             DeviceClassRegisters configureRegisters;
         };

         typedef std::vector< JointConfig > JointsConfig;
    }

The task property is of type JointsConfig. In the ruby script I do

         joints_config = task.joints_config.to_a
         joints_config.each do | joint_config |
            configureRegisters = joint_config.configureRegisters.to_a
            configureRegisters.push(
    Types::NdlcomDeviceDriver::DeviceClassRegister.new )
            joint_config.configureRegisters = configureRegisters
         end
         task.joints_config = joints_config  # This is where it crashes

I also tried something like.

             joints_config.each do | joint |
                 joint.configureRegisters.push( 
Types::NdlcomDeviceDriver::DeviceClassRegister.new )
                 joint.configureRegisters.each do | dc |
                     dc.registers.push( 
Types::NdlcomDeviceDriver::ConfigureRegister.new )
                     dc.registers.each do | reg |
                         reg.bits.push( 
Types::NdlcomDeviceDriver::ConfigureRegisterBit.new )
                     end
                 end
             end

The difference is that then the problem is changing from crash to 
following error message.

    install/lib/ruby/1.9.1/typelib/compound_type.rb:23:in `set':
    invalidated object for
    /ndlcom_device_driver/DeviceClassRegister.registers for
    /ndlcom_device_driver/JointConfig.configureRegisters (TypeError)

Let me know if you need more info.

No the task is not running.
