Unregistered property type

[captain-yoshi]

When adding this ros msg to a stage:

control_msgs::GripperCommand controller_goal;

stage->setProperty("controller_goal", controller_goal);

I get this warning:

[ WARN] [1706843311.825944146]: Unregistered property type: control_msgs::GripperCommand_<std::allocator<void> >

Do you have an idea on why this triggers ? I though that all ros msgs could be serialized...

[rhaschke]

Yes, in principle all ROS msgs can be serialized. But they have to be explicitly registered (for the deserialization system).
I guess that message originates from rviz not being able to deserialize the GripperCommand msg?

[captain-yoshi]

I think it originates from mtc.

[rhaschke]

Yes, you are right. Probably this can and should be improved... Let's see when someone finds time to do so...
The underlying problem is that properties are not templated, but essentially use boost::any to become generic.

[rhaschke]

You missed to declare the property:
stage->properties().declare<control_msgs::GripperCommand>("controller_goal");

Alternatively, you could use the following to declare (and set the default) in one go:
stage->properties().set("controller_goal", controller_goal);

Stage::setProperty is currently not templated and thus we cannot declare/register the type there.
Maybe we should change this. Opinions, @v4hn?

I also get unregistered property type warning

[ WARN] [1716837715.989871855]: Unregistered property type: std::map<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, double, std::less<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<std::pair<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const, double> > >

[rhaschke]

As this is not a ROS message, we don't have a (de)serialization method for it.
