rosrun autocomplete show all src files.

edit

when i try autocomplete at rosrun with tab key,

uesr@pc:~$ rosrun name-of-pkg [tab]
CMakeLists.txt             [executable_name]
main.cpp                      package.xml

what i expect is to see only the executable_name on autocomplete, but what i see is whole files in package folder in src

another happening :

i created 2 catkin workspace with a pkg

1. create ws1/src/ws1_pkg, do $ catkin_make

2. then create ws2/src/ws2_pkg, do $ catkin_make

3. $ source ws1/devel/setup.bash -> can't autocomplete ws2_pkg

4. new terminal $ source ws2/devel/setup.bash -> rosrun ws1_pkg shows up.

ws1_pkg shows up even if i sourced ws2 setup.bash

What's happening to me?
