I've just downloaded Icefaces and installed on JSC2 update 1.
The sample applications work fine, but I have an issues when integrating with an existing project.
I used the "iceface Integration" to convert my existing project.
I have not added any new Iceface components - just wanted to see if I could compile the project with no changes.
The project compiled ok, but when Page 1 was displayed it did not seem to be initialised properly. The fonts were wrong, and when I pressed a button the browser flagged a page error. A copy of the project without "Iceface Integration" is OK.
The manual says something about using a different JAR in mixed ICE-Faces projects but its not very clear what procedure you need to follow in this specific IDE.
