Just to clarify, I hope that by "true" you mean that id generation is turned /on/ by default. :) At least for 5.2.4. It could be off by default in 5.3. But these sorts of seemingly innocuous but actually disruptive changes (and yes: nixing the id of an element is a disruptive change!) should happen incrementally. Eg: 5.2 introduces the ability to turn off id generation in the label component, leaves ID generation ON by default, and warns in the upgrade notes that the next version of tapestry will turn ID generation in labels /off/ by default. Then 5.3 turns it off. And /maybe/ in 5.4, we remove the flag... maybe. This is the basic model that the cayenne team has used to migrate the cayenne api and it has worked very well. Upgrades are painless. I've never had a cayenne upgrade require more than about 20 minutes of my time, even when I upgraded an app that made fairly advanced use of cayenne from 2.x to 3.x. There were deprecation warnings, to be sure. But I could still deploy a perfectly functional application, and get to the deprecation warnings as time allowed. The important thing is that even with deprecated methods, the old /behavior/ was preserved. It's a policy we should adhere to more in Tapestry. What users need /most/ from the framework is dependable behavior; in large part, they need that more than the few bytes of bandwidth saved by removing the id from the label component.
