The scm-sync-configuration plugin raises the following alert when loading a job configuration using IE8:

Something went wrong with the scm-sync-configuration plugin !
Please report a JIRA with as much informations as possible (browser, os, current url, error message etc.).
Error message : Cannot retrieve target form on current page !

This only happens in IE8 (Firefox throws no warning), and if you are accessing the job configuration through a View other then the default (All) view. Accessing the job through the "All" view does not raise the error. For example, the following does not raise an error:

http://localhost:8080/job/my_test/configure

But this URL does (but only in IE8, not Firefox):

http://localhost:8080/view/Tests/job/my_test/configure
