Hi all,

When I tried to create a 2-dim array with ROS's srv, I had

some troubles with the server side.

from file "srv/Joints.srv":

float32[] joints

from file "srv/ImportPC.srv":

float32[] jts

---

Joints[] trajectory

In server.cpp, I tried to push_back a new Joints to trajectory like this:

res.trajectory[0].joints.push_back(sum);

It compiles, but of course at runtime it fails because trajectory[0] doesn't exist.

So I tried something like this:

import_pc::Joints_<std::allocator<void> Jts ();

Jts.joints.push_back(sum);

res.trajectory.push_back(Jts);

However the template for import_pc::Joints_ is not correct. Any suggestion would be really appreciated.

Thank you so much,

Paul
