Hi, I'm working on some reporting stuff in our application. One of few different reports should include activity on last modified objects. The query for now looks like this: select date(insp.lastModificationDate), insp.modifiedBy, insp.description.length(), insp.products.size(), insp.picture from

Hello, we're porting a JDO application to ObjectDB which uses uuid-hex generated values. However the page on generated values in your JPA tutorial only mentions numeric generated values, and when we try to use it the error message seems to imply that auto- generating strings isn't supported
