Yes, it isn't an issue in 2.5.4, although it's come to my attention that this is fixed in 2.5.6 as well, so I reocmmend upgrading to that version.

We are about to upgrade from 1.10.x, and we're debating whether to go w/ 2.5.4, or 2.5.6. Can you confirm whether this flaw was introduced with 2.5.5 and is therefore not present in 2.5.4?

Thanks!

Thanks.

We can watch for the change in 2.5.7

Thanks. This is logged in our tracker as JIRA ID CS-10359 with a fix date of 2.5.7. The fix sends the group ID through the cluster instead of the group object (since it isn't serializable). I talked to Sean and he said you all were able to resolve the issue already, but I can share the code once it has passed review if you would like to see that.

Thanks,

Vinh

I was testing this with Tom. No is the answer. This was tested with two plain 2.5.5 installs.

Were you using LDAP when you encountered the error in 2.5.5?

I have run a couple of tests with this. I setup two 2.5.3 instances clustered and tried to create a group which worked perfectly. I then proceeded to clean out the database, set up two instances of 2.5.5 and tried to create a group. Got the same error. I did not have a 2.5.4 war file to test with.

I tried building a new war file, overlaying the JiveObject class and having it implement Serializable. That test failed as well with the same error as above.

The one thing different...the license file is for 2.5.3, but I would think that if that was the problem then it would fail with creating communities etc. I can create communities and blogs and they distribute through the cluster fine.

Have run into this problem when trying to creae a group on two clustered 2.5.5 instances. Client has two instances of CS 2.5.5. We enabled clustering right after both instances were up and running and both instances see each other.

The first order of business for the client was to create some groups. Any attemt to create a group results in an error. The admin console displayse this error:

Clearspace Admin Error

(Wrapped) java.lang.Object

This is what the console/error log shows:
