This gives me the error:

2009-02-05 09:11:54,097: [http-130.133.2.116-9080-Processor21]
ERROR GrouperCapableAction.execute(281) -
java.lang.RuntimeException: edu.internet2.mid
dleware.grouper.exception.SchemaException: invalid group type:
for group name: test:abc123,
GroupType[creatorUuid=b0bb6118-c6b9-4d37-8257-61dcee19b4c

6,createTime=1231229012373,fields=12,isAssignable=false,isInternal=false,name=base,uuid=fc8eff6c-6812-4a10-8891-133df83bfbb5]:extension

The UI says that the group was saved successfully, but also that an
error occurred. When I click on the group in the UI to get the group
summary, I get the standard error message.

So I tried the second method (see below) ...

This works. The group type is added with the attributes

gid <empty>
id <same as uuid>

However, my definition of the group type looks like

<registry>
<metadata>
<groupTypesMetaData>
<groupTypeDef name='fubGroup'>
<field name='gid' required='false' type='attribute'
readPriv='read' writePriv='admin'/>
</groupTypeDef>
</groupTypesMetaData>
</metadata>
</registry>

so where does 'id' come from?

Another thing I am not sure about is how I would do an insert into a
table such as "fub_group_ids" to get a gid from a sequence which I can
then write into the 'gid' field of my customised type. I am not too
familiar with hibernate, but assume this would be the way to go, right?

Thanks for all your help,

Loris
