T6015 cannot-cache

cache on a screen that is not open to anyone, or one of whose data entries is not.

Details

The engine keeps a screen that states cache for nobody, so every entry it reads is the same for everyone: a screen that is open to 'anyone', whose entries read what anyone may read. A member of an agent and working are never the same for every visitor. A component that the screen uses may read what is a visitor's own: it is a personal part, drawn for each visitor and never kept (option.component.personal).

cache: 60_000,
data: { orders: read(openOrders) },   // T6015 where openOrders is for signed-in callers

The fix

Read only what is open to 'anyone' on a screen that is kept, or take cache away.
