It is possible to extend the size of the columns XWS_VALUE in the table xwikistrings in the MySQL database. I've run in some cases where a bigger field is necessary without wanting to move to a TextArea. I think it could make sense that we make this field bigger in the xwiki hibernate mapping Ludovic Le 07/12/10 12:10, farouk korteby a écrit :
Hi,
The string property is limited to 255 chars, you must use text-area property.
Take look at \xwiki-enterprise-jetty-hsqldb-2.0.2\webapps\xwiki\WEB-INF\lib\xwiki-core-xx.jar
xwiki.hbm.xml
<joined-subclass name="com.xpn.xwiki.objects.StringProperty" table="xwikistrings"> <key> <column name="XWS_ID" /> <column name="XWS_NAME" /> </key> <property name="value" type="string"> <column name="XWS_VALUE" *length="255"* /> </property> </joined-subclass> -----------------------------------------------------------------------------------------------------

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?
