It's good to see the debate on the differences between ADDT and the WA extensions is still alive and that WA are open to the potential for integrating applicable ideas into future releases.
I for one have been a long time user and beta tester for many of the old InterAKT extensions, and still use MX Kollection and ADDT on various projects.
While I have had access to many of the WA extensions, and currently own most of their commercial extensions, I still rely on the older Interakt products, simply because they have so many features that I cannot live without for RAD.
As mentioned in an earlier message, there are various features that really need to be implemented to make the Framework and DA of a true use to many users.
Personally, I find the lack of sortable and movable data lists a large omission to the product line. Something I can imagine a large portion of web developers using the WA products also feel.
I also agree that the transaction engine was a very good system for making more complicated actions much quicker to implement into a web site.
Finally, the way that DA creates multiple pages for each of the stages certainly adds to the bulk of the site, and also makes integrating them in to your design a more time consuming process. ADDT's method of one page with multiple actions was certainly quicker and easier to work with, as was the ability to go back in and edit your existing code.
If some of these features could be integrated into future WA products, then I think there would be a lot of happy developers out there.
