When you put a lab availability in public or local and you remove it. It doesn't remove the data from database.
Problems when you use id = "", in few cases i can use this id, and we shouldn't use it. It can be solved by changing the order the if sentences in functions _changeaccessibility and _change_publicavailability
I can put only blanks in form. I think we should reject it.
The form remembers the last id. Because we didn't clean the var _lab.publicidentifier in functions _public_availabilityformatter and _accessibilityformatter.
We have a few issues in page http://localhost:5000/admin/rlms/labs/ :
