Andrus Adamchik updated CAY-2700:
---------------------------------
Description:
We need to standardize date[time] String representation in Cayenne expressions
to be ISO8601.
Some background ... When parsing Cayenne expressions we do not attempt any type
conversion of parameter values. This is usually not a problem for Cayenne
users, as they can pass parameters already converted to a need type (e.g.
LocalDateTime). However this is an [issue for frameworks like
Agrest|https://groups.google.com/g/agrest-user/c/MxFktjHhXGI] that can not do
proper parameter conversion as they are not aware of the left-hand side of an
expression matched with the parameter.
So let's implement a more robust conversion inside the Cayenne stack. We can
probably do it right in the ExtendedType. E.g. ExtendedType for String can do a
ISO-8601 String to date[time] conversion based on the passed JDBC type.
