I'm having the same issue... see here: [url]http://websphere-screencasts.s3.amazonaws.com/PortalProjectWiringIssue.mov[/url]
This is unfortunate because each time I deploy my Portal project, the wiring is reset.
WPS 184.108.40.206 and RSA 7.5. I'm going to try updating to 7.5.1 to see if this issue goes away. In the meantime, any help is appreciated.
