James, One of the reasons we haven't switched is because Geoff's Spindle wasn't there. So, I agree, that tools are important. My point was, that most Tapestry Users won't migrate over to JSF just because we have to upgrade. I agree that Geoff has had an extraordinary bad time of providing an upgrade to Spindle for 4.x. However, I read his e-mails and the problems that he is encountering are, in a large part, due to the framework gone wild of 4.x.
The main reason that 5.x exists is because 4.x is such a wild child. It has gotten out of control. The reason that 4.x exists AT ALL is because, as Howard was writing the next version of Tapestry, people were complaining that there wasn't any upgrade path. That the differences between 3.x and 4.x of old were so different that everbody was complaining. Everyone wanted 4.x as an intermediate version. It is there for those who couldn't use 3.x and didn't want to wait for 4.x. So, in reality, 4.x is just a stop-gap, not to denigrate all the work Jesse, et.al. have contributed (he is a wild man). The "next generation" of Tapestry is not 4.x or 3.x, it is 5.x. Should Geoff have done 4.x? I think he did it because we pushed him into it because we weren't willing to wait for 5.x. Bottom-line, 5.x is the future, 3.x and 4.x are prototypes and support will decline for both of them as 5.x becomes the standard. With that said, if Howard has some brilliant idea and abandons 5.x, all hell will break loose. But from his e-mails, the plan is to maintain and enhance 5.x for the future. All roads lead to 5.x regards, Mark -----Original Message----- From: James Carman [mailto:[EMAIL PROTECTED] Sent: Tue 8/1/2006 9:06 AM To: 'Tapestry users' Subject: RE: Tapestry 5 Discussions Mark, you also have to consider a different type of user. For me, a component/framework extension developer (Tapernate, tapestry-acegi, etc.), I am not going to want to rewrite all of my cool stuff each time a new version of Tapestry comes out. No way will I maintain a version of my components for each version of Tapestry. What about Trails, which is helping Tapestry gain some attention by providing a cool RAD environment? If innovative folks get sick of having to rewrite their stuff all the time, then they'll just stop writing components for Tapestry altogether and that'll hurt the community. Also, what about tool developers? The cognition folks have a pretty cool Eclipse plugin that will probably have to be reworked for T5. Spindle also suffered the same growing pains. I don't want to put words into Geoff's mouth, but he seemed somewhat troubled by the fact that he had to totally rework Spindle for T4 from T3. Hugo Palma is creating a TapIDEA, an Intellij IDEA plugin. He'll also be impacted by this as his IDE extension will probably have to be completely reworked. I know that some folks aren't very impressed by tools and they don't think that tool support should be the reason that people choose a platform, but to some they are very important. -----Original Message----- From: Mark Stang [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 01, 2006 10:25 AM To: Tapestry users; Tapestry users Subject: RE: Tapestry 5 Discussions I don't think I agree. We switched to Tapestry from Struts because it gave us a component framework. Internally, we have three projects on Tapestry. One is 4.x and the other two are 3.x. For the 3.x projects we have looked at 4.x and while we would like to be on the latest and greatest, there isn't enough of a ROI to justify moving at this time. And since 5.x is in the "near" future we are waiting. However, we might not ever upgrade. What would cause us to upgrade? Everything works. And when we have had problems we post it to the group, which usually results in a fairly quick fix. Or if push comes to shove, we pay Howard. What more could you ask of a framework? And if you think about what brought us to Tapestry, it wasn't the upgrade path or support, it was the ability to develop components. >From everything I have read, we will still have "pages" and "components". Will we have to rewrite all of our components? I don't think we will have to do so, mainly because they are not that tied to the API. regards, Mark -----Original Message----- From: Danny Angus [mailto:[EMAIL PROTECTED] Sent: Tue 8/1/2006 7:51 AM To: Tapestry users Subject: Re: Tapestry 5 Discussions > Finally, let's take a sober look.

On the other hand tapestry provides us the the ability to re-use components. If we want to write new applications in Tapestry5 do we throw away all our old components and lose their value? Or do we go to the expense of migrating them and writing new ones? For the people who are stuck requiring support for product which is likely to be ending its life the choice will be a stark one, not whether to upgrade to Tapestry 5, but what framework to migrate to. I would predict that most of the people who see their investment in components become increasingly worthless will have little loyalty left and will plump for something which is more likely to protect their investment, no matter what the technical limitations are. Look out for people offering a Tapestry4 to JSF migration path. d. **************************************************************************** *************************** The information in this e-mail is confidential and for use by the addressee(s) only.
