The reason is the broken LOOKUP-TRANSFORM function call, which throws the following error: "Not connected to an action server. Cannot send goal." My question is: is there anything one needs to explicitly change in their own code due to the switch to TF2? As TF2 works through action calls, do I need to start the action server by myself and how do I do this? As most of this changes have been made during the two weeks of Christmas and New Year's it's hard for me to track the changes in the repositories. Any help? Thanks in advance.

Just grep for tf2 in rostopic list - it should show (I think) "/tf2_buffer_server", and "/tf2". Again, I'm not in front of a computer right now, so hopefully those are correct. Did you start the ROS node? Because the action server is connected via a ROS init function. So far from my side, Cheers, Jan > On 30.01.2015, at 14:46, Gayane Kazhoyan wrote: > > Dear CRAM developers, > > After the recent change from TF to TF2 in our repositories, resolving location designators stopped working for me.
