update single field does not work

[tanya]

It's not a good practice to make field dependent on itself.

[Vincent]

I have done the following thing in official demo (version 5.2.5)

I set the following in type field of Account Entity

Conditions making field read-only (if account record is not newly created or type is not Investor, set account record be read-only)
(
(
Type ∉ (Investor )
OR
Created At = ∅
)
)


if i click the "EDIT" button, then update the type from investor to customer, the type value changes to is "customer" after clicking "SAVE".
however, when i only update the type from investor to customer by clicking the pen symbol near type field, the type value is still "investor" after clicking update.

how can these single field be updated using pen symbol near type field (single field update)?


Thanks.
