Do you foresee easy integration between these components (no custom viewhandlers required etc)? It appears as if JSF 2 makes stuff easier to put things together. And hopefully the new exception handling doesn't do as much swallowing is before...
Integration should be significantly easier with ICEfaces 2.0 for two reasons: rendering is not longer performed through a custom ViewHandler (RenderKit decoration is supported in JSF 2.0) and ICEfaces 2.0 Ajax Push is implemented via a notification/refresh strategy (eliminating the Request/Response virtualization of ICEfaces 1.8).
Do you have a prototype application that you can try with the ICEfaces 2.0 Alpha?
Yes, I have a EE 6 playground (ICE2/JSF2/JPA2/CDI/BV) application but I'm waiting for the components-enabled-version of ICE2 before doing any in-depth prototyping.
Love the lack of xml configuration in EE 6. Still noticed more hits to my backing-bean getters than I has expected, though but the libraries are not final, I guess.
