---- Yes, converting dates to Strings are a no-go. I don't see us being able to fix that on the short run. Could you try a parameterized expression instead (using $param instead of date literals). On the other hand, we need some way to handle dates or other parameters that can't be converted into literals... I guess one way is to generate "synthetic" parameters and collect values in a map passed as an argument. ----The problem is that I can't use parameter based expressions as they are constructed elsewhere (as instances of Expression) and re-used in various places (including in-memory).
Is it not possible to re-use whatever code in Cayenne already converts such values (depending on the associated DbAttribute, for example)?
