With a float, PersistenceBroker.getCollectionByQuery() throws
MetaDataException
Accouding to stack trace, The error's reason is treating value as double instead of float when invoking setFee(float fee).
I wonder that is from wrong configuration. Then I made a test with a very similar object. But test runs.
So I can't understand what is happening.
If you have some idea, please tell me.
This is from my repository_user.xml
<field-descriptor
name="fee" column="FEE" jdbc-type="FLOAT" />
Here is stack trace.
