[richfaces-issues] saving state for simpleTogglePanel or panelMenu

Hi, I'm just getting used to RichFaces (I like what I see so far), but there are some things that seem like they'd be obvious to me that I can't quite figure out. So hopefully someone here can point me to a resource, or at least confirm that the components are behaving like they're supposed to. I am using 3.1.2GA on JBoss 4.0.5. Specifically my problem is that I can't find a way to get simpleTogglePanel to remember it's expanded state between page views. I bound opened to a boolean, but that's obviously not updated by the engine no matter what switchType method is used. The documentation rather unhelpfully says "The component could also have an "expanded" (true/false) attribute responsible for keeping a panel state." I suppose it could also give me winning lottery numbers, but I get the feeling the wording should probably "should have this attribute but doesn't". So what's the common way people make these components save state? I think I can also get panelMenu to do what I want, but I'd hate to endlessly play with components only to find it suffers from the same limitation. It's documentation seems to say nothing about a model to save its state between page views. Anyway, I hope someone has suggestions for me. My guess is that in most conditions you'd want these things to save their state, so it can't be an uncommon problem to overcome. Thanks for any help you can provide, and I hope I'm not off the topic of the list. Mike
