I am losing the field level security on fields which I deploy to production using Change Sets. This is a problem which has been discussed on here in the past :
Deploying From Sandbox (Enterprise) - loss of permissions, field security, etc
However, I have some further questions regarding this. If I am understand this all right then this is a serious drawback to deploying fields because it sounds like we are required to deploy all of the profiles from the said sandbox to production as well in order to maintain the proper field level security ... ???
If that is true then am I required to deploy ALL of the profiles in order to account for a field which is meant to be visible and editable by ALL profiles ? If that's true then that's crazy !
So far I have only deployed through Change Sets. Will Eclipse maintain the field level security if you use it to deploy new fields ? I've tested it on a couple of fields but only going from Prod -> Sandbox, not Sandbox->Production.
Thank you very much for your help and insight.
