Erez:
I had the same problem with ICEFaces/Facelets, and spent quite some time before getting it right:
1- new WEB EE5 project
2- add JSF capabilities (NO facelets support at this stage !)
3- add ICEFaces support
4- and LAST: add ICEFaces Facelets support
Logical maybe, but not obvious ! Since ICEFaces is 3rd party, the ICEFaces Facelets option cannot be offered at stage 2. I feel a little help from ME for smoother integration should be offered here. At least, these steps should be documented (in bold).
BTW: thank you all ME people. Integration of 3rd party plug-ins in 6.0.1 was a neat feature.
regards,
Jean-Michel
