So, I tested a couple of scenarios and here is my finding.
When I save the address and the website from the edit dialog of an organization, the data is saved both in ost_form_entry and ost_form_entry_values as well as ost_organization__cdata
If I try editing the same organization again - the values appear in the edit dialog box.
However, if I delete ost_form_entry and ost_form_entry_values - but don't delete ost_organization__cdata then the values DON'T appear in the edit dialog box.
So the behaviour is that osticket is retrieving the values from the form_entry and form_entry_values tables. Is this the correct behaviour?
