[ http://opensource.atlassian.com/projects/hibernate/browse/ANN-657?page=co... ] Michael Grünewald commented on ANN-657: --------------------------------------- Hi, a little bit more flexible way, would be to define an method which is accessed before the mapping and only the result is mapped. E.g. for enums the method would be "name" (public final String name()) or "ordinal" (public final int ordinal()) So an @MapKey (action=name) would cause that name is called on every key and mapped as String. This would be also usefull if the key is an class which should not be mapped to the db. So "hashcode" or toString could be another example for an usage of that. I'm not quite sure if there any other useful situations out there, but at least it would be very flexible and powerful. On the other hand the "enumerated" would be more straight forward. Greetings Michael By the way, same should be aplied to @MapKeyManyToMany. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

Using hibernate tools, the column was declared as a bytea (pgsql). The workaround I found is to manually map the key, it should be fairly doable for STRINGs too... @MapKey(columns = @Column(name = "my_column_name", nullable = false), type=@Type(type="org.hibernate.type.EnumType",parameters={(a)org.hibernate.annotations.Parameter(name="enumClass",value="my.enum.class.Name")})) Anyway, it would be nice to get an annotation to fit this requirements as it was the case in the old version :) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
