wid does not display anything from the undulator while undulator are not reached once
OH [1]: wid()

You can see that it is empty
Let's trig an undulator which was already part of the session
OH [2]: u18u
Out [2]: AXIS:
name (R): cpmu18a
unit (R): None
offset (R): 0.00000
backlash (R): 0.00000
sign (R): 1
steps_per_unit (R): 1.00
tolerance (R) (to check pos. before a move): 0.001
motion_hooks (R): []
limits (RW): Low: 0.01000 High: 500.00000 (config Low: 0.01000 High: 500.00000)
dial (RW): nan
position (RW): nan
state (R): DISABLED (Axis cannot move)
acceleration: None
velocity: None
CONTROLLER:

type cpmu18a.controller for more information
TANGO DEVICE SERVER VALUES:

CPMU18a_GAP_Position = - mm

cpmu18a - - DISABLED
wid displayes now something
let's trig another undulator
OH [4]: u27d
Out [4]: AXIS:

OH [5]: wid()

cpmu18a - - DISABLED
u27c - - DISABLED
Now both are displayed
