Mule ESB 3.4.2 Release Notes

Adding a cluster to a group

If you place a cluster in a server group, you may experience issues with deployments which target the group instead of the cluster directly.
Workaround: Use the cluster as one of the direct targets of your deployments. If you experience issues, check the apps directory in your Mule server(s) to confirm functionality.

Adding a server to a group

If you add a server to a group via the server details panel (using the settings tab and editing the server info), deployments targeting the group are not transferred to the newly added server.
Workaround: Use the Add to Group button in the server list grid.

Error Messages

Some error messages in the MMC main window may contain a "See More" link which, when clicked, displays a new window containing only the text null.
Workaround: There is no applicable workaround, but you can safely ignore this issue.
