Andrus Adamchik updated CAY-2700:
---------------------------------
Description:
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
date[time] conversion based on the desired JDBC type.
