Could you be more specific as to the type of property.
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.
Moreover, do you try to change the property while the component is running ?
No the task is not running.

Hi all,
I have a complex property with std::vector (sub-configs) inside std:vector
(configs). I am trying to modify the property from ruby script.
Changing any already existing value works fine. But once I try to push a new
element to the sub-configs and then write it back like
configs = task.configs.to_a
configs.each do | config |
sub_configs = config.sub_configs.to_a
sub_configs.push( Types::SubConfig.new )
config.sub_configs = sub_configs
end
task.configs = configs
it crashes. Does anybody know how this can be achieved?
