Finish not enabled when unprotecting titleCache in new Person dialog
Using the new person dialog, at the beginning the title cache is protected. Therefore entering data e.g. into "family name" does not change the titleCache. It is still empty and therefore the "Finish" button is still disabled.
Now clicking on unprotected fills the titleCache and therefore the Finish button should be enabled, but isn't.
Please check if this might also be the case for other "New" dialogs.
