I get the following error when setting STATE_SAVING_METHOD to “client” in web.xml. It works fine when set to “server”. I replaced the jsf-api.jar and jsf-impl.jar with different copies not created by MyEclipse and it works fine set to both “server” and “client”. Any ideas?

MyEclipse Version: 3.9.100
Build id: 20050508-4.0-Milestone-1

We ship the Sun RI and MyFaces implementations of JSF, they are vanilla, unchanged copies of the libraries. 1) What implementation did you use when you first added JSF Capabilities and 2) what implementation of the two jars did you drop into your project?

I’ve tested this locally and it works fine with both client and server using the libraries we ship (most recent releases AFAIK).

We used the Sun RI. We tried to recreate the problem by going back to the jars supplied by MyEclipse, but everything seems to be working now. I have no idea. Sorry for the trouble and thanks for your time.
