…ds#2403

Before this change, when set property
exo.feature.PostToNetwork.enabled=false, launch server and create spaceX
then on spaceX AS and choose poll then create poll and save, POST button
is disabled.
After this change, As poll is created&saved, Poll button is enabled and
once submitted poll is posted.
