We have tried to use the principle "convention over configuration", i.e.
provide as good default values as possible.
I don't think "no cascade" is a good default value.
The logic behind the default value for cascade can be found in
DatabaseGenerationHelper.getDerivedCascade
What we could do is to place the values for the different cases in
generator.properties to simplify customization. Alternatively it is enough
to customize with oAW AOP and overwrite the getCascade function in
dbhelper.ext
You mention FaultTimer and FaultType. Is that a typo?
I guess you know that you can define it as:
Entity FaultTimer {
- @Fault fault cascade="none"
}
