[xwiki-devs] Data too long for column XWS_VALUE

Hi devs, I have a serious problem. I'm using a fresh XE 2.6 with MySql (fresh db + XE 2.6 XAR import) and I'm doing this: 1. Create a class Main.TestClass with only one property (say "city") of type "String". 2. Add an object of type Main.TestClass to Main.TestClass page and set the value of "city" to a large string (say 270 characters). 3. Save. I get: ----------8<---------- org.hibernate.exception.DataException: could not insert: [com.xpn.xwiki.objects.StringProperty] ... Caused by: com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column 'XWS_VALUE' at row 1 ---------->8---------- IMO "Data too long" should be only a warning. Why isn't the string simply truncated if it's too long? If I go back to the object editor the value of the "city" property is empty. If I try to set the value to a short string, say "Paris" and then save, I get: ----------8<---------- Failed to commit or rollback transaction. Root cause [] ... Wrapped Exception: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [com.xpn.xwiki.objects.StringProperty#<?xml version="1.0" encoding="UTF-8"?> <city>Paris</city> ] ---------->8---------- So how can I fix this? If I delete the object and then create a new one, setting the value of "city" to "Rome" I get the same exception as before, but with: <city>Rome</city> Is this related to my configuration? Thanks, Marius
