Juan Antonio Agudo commented on HHH-2946:
-----------------------------------------
There seems to be some kind of limitation to what you can do with yout index column.
Turns out this problem is not restricted to Annotation behaviour.
If you do:
<map name="settings" >
<key column="id" />
<index column="keyValue" type="string"
length="255"/>
<element column="value" type="string"
length="1024" />
</map>
you get a Table that looks perfectly okay:
mysql> desc testentity_settings;
+----------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+----------+--------------+------+-----+---------+-------+
| id | bigint(20) | NO | PRI | | |
| value | text | YES | | NULL | |
| keyValue | varchar(255) | NO | PRI | | |
+----------+--------------+------+-----+---------+-------+
However if you decide you want a text field as your index column:
<map name="settings" >
<key column="id" />
<index column="keyValue" type="string"
length="1024"/>
<element column="value" type="string"
length="1024" />
</map>
The DDL Creation fails and everything just dies. This is not doumented behaviour as far as
I know.
@AttributeOverride of column type or name results in
PropertyNotFoundException

Key: HHH-2946
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2946
Project: Hibernate3
Issue Type: Bug
Environment: Hibernate 3.2.5.ga, Annotations 3.3.0.ga, Spring 2.0.7, MySQL
5.0.41-community-nt, Windows Vista
Reporter: Juan Antonio Agudo
Attachments: hibernateErrorTest.zip
When trying to map a java.util.Map<String,String> hibernate by default creates
VARCHAR(256) fields. When an attempt to alter for e.g. the column type to "TEXT"
an Exception is thrown. For example:
@CollectionOfElements
@AttributeOverride(name="element.value",
column=@Column(columnDefinition="TEXT"))
public Map<String, String> getSettings() {
return settings;
}
results in
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'sessionFactory' defined in file
[C:\Users\tag\workspace\xyz\conf\applicationContext.xml]: Invocation of init method
failed; nested exception is org.hibernate.PropertyNotFoundException: Could not find a
setter for property bytes in class java.lang.String

This behaviour can be reproduced and was described fully in
http://forum.hibernate.org/viewtopic.php?p=2368889#2368889
I attached an isolated sample code for review purposes.
