Hi All, I created a JDO class, which had some attributes, and I created some CRUD operations, all of them worked correctly.
Then I added a new attribute in the JDO class, and then set value to it and persisted it as usual when I executed CRUD operations. The problem is that I cannot retrieve the value of the new attribute in program, the value is always null. But when I check the value in "Datastore" -> "Data Viewer", the value is correct. So i'm wondering why it cannot be retrieved in application. Is there some cache mechanism? Thanks in advance!
