Nodelets not running together

edit

I'm trying to run 4 nodelets together, but for some reason the last 3 seem to be incompatible with each other. That is out of the last 3 which ever one is loaded first, it runs but the rest don't run. Nothing crashes but the nodelets simply won't subscribe or publish anything! I'm really unsure what is happening, been stuc on this for the past 3 hours.

This is the single executable node :

This is the cmakeLists :

This is the xml :

This is how the pose estimation nodelet is initialized:

This is how the display nodelet is initialized :

This is how the chase robot is initialized :

Any help would be greatly appreciated!
