Martin,

I am getting the following errors when trying to get one of my ecore
model initialized with the table_per_class strategy:

SchemaUpdate.java: 155 : Unsuccessful: alter table `xmlall` add index

I saw a method in PersistenceOptions, getMaximumSqlNameLength, would
that help avoid this?

Also is there possible to implement a different naming strategy for FK
names that would be more meaningful?

Thanks
Alain
