I would appreciate some pointers at what is wrong with the following.
I am deploying a VFP and an Apex class in to production using change sets, but the profile settings keep getting lost.
On the production box, before deployment happens, the VFP has "Support Engineer" and "Support Leadership" in the enabled profiles, I checked these via "Setup | Develop | Visualforce Pages | [My VFP] | security".
On the dev box I create an outbound change set that as "Support Engineer" and "Support Leadership" listed in the "Profile Settings For Included Components" section as well as the updated VFP and class.
The change is uploaded to production.
On the production server the change is successfully validated and deployed but when I revisit "Setup | Develop | Visualforce Pages | [My VFP] | security" the "Enabled profiles" list is empty and I have to add them in manually.
What am I doing wrong? How should I deploy access rights to my page and class?
