Re: [Xorm-devel] Re: fields changes type

[Wes B. <we...@ca...>]

I got both copies you sent, but sometimes SourceForge lists are slow.

Specifically for primary key mappings there is an extension you can use 
in your .jdo file.

<class name="MyPersistentClass">
  <extension vendor-name="XORM" key="table" value="my_table" />
  <extension vendor-name="XORM" key="datastore-identity-type" 
value="java.lang.Long" />
  <!-- fields etc -->
</class>

Looks like this never made it into the documentation.

Anyway, this will basically cast all your primary keys to 
java.lang.Long, since that is what they look like coming back from the 
database.
