Grouper Users - Open Discussion List

First of all, be sure to check the logs when you get an error.  There will be 
more info there.  GSH will tell you where the logs are when it starts up if 
you are not sure.

Second, are transactions enabled in your database?  i.e. if you insert 
something, can you roll it back, or not?  It depends on the table type in 
mysql.

Third, for reasons I don't know, you cant call group.store() in a post insert 
hook, so if you remove that line, it should work.  Here is a thorough example:

Let me know if it doesn't work.

Thanks,
Chris

OK, I started from scratch with grouper 1.5.3. I created the groupType 
"posixGroup" with the Attribute "gidNumber". Then I created the file 
src/test/GroupAddUosHook.java with the content that you have listed on 
the web page (I changed the class to GroupAddUosHook, the type to 
posixGroup and the gid attribute to gidNumber). I called "ant dist" and 
started the grouper shell. When I call the addGroup command I get the 
following errors:

gsh 0% group = addGroup("uos", "test", "test");
// Error: unable to evaluate command: Sourced file: inline evaluation 
of: ``group = addGroup("uos", "test", "test");'' : Error invoking 
compiled command: :  Error in compiled command: 
java.lang.RuntimeException: State was never stored from db,
Problem in HibernateSession: HibernateSession: isNew: false, isReadonly: 
false, grouperTransactionType: READ_WRITE_NEW,

false, grouperTransactionType: READ_WRITE_NEW,
Problem in HibernateSession: HibernateSession: isNew: true, isReadonly: 
false, grouperTransactionType: READ_WRITE_NEW

The commands getTypes() and getAttributes() cannot be found.

gsh 1% group.getAttributes()
// Error: unable to evaluate command: Sourced file: inline evaluation 
of: ``group.getAttributes();'' : Error in method invocation: Method 
getAttributes() not found in class'java.util.LinkedHashSet'
gsh 2% group.getTypes();
// Error: unable to evaluate command: Sourced file: inline evaluation 
of: ``group.getTypes();'' : Error in method invocation: Method 
getTypes() not found in class'java.util.LinkedHashSet'

The group has been created and it has a gidNumber of "2".

gsh 3% getGroups("uos")
group: name='uos:test' displayName='Uni Osnabrueck:test' 
uuid='aefd90fdfec04d5c809c431761e8b416'
gsh 4% getGroupAttr("uos:test", "gidNumber")
2

But, interestingly, I cannot delete the group:

gsh 5% delGroup("uos:test")
// Error: unable to evaluate command: Sourced file: inline evaluation 
of: ``delGroup("uos:test");'' : Error invoking compiled command: : Error 
in compiled command: 
edu.internet2.middleware.grouper.exception.GrouperException: unexpected 
condition,
Problem in HibernateSession: HibernateSession: isNew: true, isReadonly:

gsh 6% getGroups("uos")
group: name='uos:test' displayName='Uni Osnabrueck:test' 
uuid='aefd90fdfec04d5c809c431761e8b416'

Do you have any idea, what could be wrong?

Greetings,
Dirk
