Tapestry 4.0-beta-3 is now available; it's more bug fixes. I've reworked how automatic cursor positioning works; it's no prioritized: first field in error, or first required field, or just plain first field. You can now turn off automatic cursor positioning (aka "focus") but settting the enclosing Form's focus parameter to false.
I've also started reviving the Virtual Library example. I'm having a little trouble getting McKoi DB deployed into JBoss 4. I briefly considered switching over to Derby, but that's not available via the Maven repository yet (still alpha).
The Virtual Library will change quite a bit as I get it working for Tapestry 4.0, as I rework it to use all the nifty features (including annotations). I'm keeping notes to form a more general Tapestry 3.0 -> Tapestry 4.0 upgrade guide.
Meanwhile, after much too long, the TapestrySupport.com web site has gone live, and a press release is going out. This is a site dedicate to professional support of Tapestry. Check it out!
