Hi,
I'm currently porting some code over to a new Nodelet
setup and I'm running into a small issue. We're using
MessageEvent subscribers to find out from where some
messages come from on topics with multiple publishers.
The thing is, when these publishers are from nodelets,
they all appear to come from the nodelet manager's node.
From what I can figure out, this comes from the fact
that ros::this_node::getName() is used to fill out
message headers. Since this seems to be attached to the
process itself, it
won't contain the name of the ros::NodeHandle from
which the publication was created.
We do have have a workaround: running these specific
nodelets as standalone, but it somewhat beats the whole
point of writing them as nodelets. I do realize that
changing the "callerid" header field behavior might have
some important repercussions over the whole API, but
would it be possible in a future revision ? Does anyone
have a better workaround idea ?
Thanks,
