ddynamic_reconfigure's Issues

problem with DDString

hi,
Thanks for sharing this code.
I tried to copy the example given in the README.md file and had a problem with rqt_reconfigre:
doronhi@ubuntu:~$ rosrun rqt_reconfigure rqt_reconfigure
I then try to open the object in the rqt_reconfigure's GUI and get this error:

[ERROR] [1540211050.795114]: bad callback: <bound method Client._descriptions_msg of <dynamic_reconfigure.client.Client object at 0x7fb137260050>>
Traceback (most recent call last):

raise DynamicReconfigureParameterException('parameter has unknown type: %s. This is a bug in dynamic_reconfigure.' % type_str)
DynamicReconfigureParameterException: parameter has unknown type: string. This is a bug in dynamic_reconfigure.

I tried removing the string parameter and everything else works.

I tried running:
rosrun ddynamic_reconfigure_python example.py
It also shows a string parameter but everything works fine now.

It seems to me that something is different in the way python and C++ implements the DDString object.
Or, any suggestions as to what am doing wrong?

Attached is my code:

void MyNode::registerDynamicReconfigCb(ros::NodeHandle& nh)
{
ROS_INFO("Setting Dynamic reconfig parameters.");
// DDynamic setup stage
_dd = std::make_shared<ddynamic_reconfigure::DDynamicReconfigure>(nh);
_dd->add(new DDInt("int_param", 0, "An Integer parameter", 50, 0, 100));
_dd->add(new DDDouble("double_param", 0, "A double parameter", .5, 0, 1));
_dd->add(new DDString("str_param", 0, "A string parameter", "Hello World"));
_dd->start(callback);
ROS_INFO("Done Setting Dynamic reconfig parameters.");
}
