回答1:
Presently, I don't believe there is a solution to this issue. I was working on the same thing yesterday for about 8 hours. See this page on the icefaces bug tracker: . They actually have the issue marked resolved, and have tutorials that claim that icefaces integrates with SWF 2.X, but the simple fact of the matter is this little line of code in their seamutilities.java class:
if (true)
{
throw new UnsupportedOperationException("Implement SWF integration");
}
I've tried running various version of icefaces before the fix was implemented on up through the current beta, and I still have issues. I'm going to say presently, the two are not compatible.
回答2:
i am getting this exception with ice forums, and as a workaround i use jsf form instead of iceforums and so far it's working fine with me.
