Perhaps I am too set in my ways, but when I think of creating something generic to format an address I think of that as a UI-level thing, preferably represented in something as close to the UI as possible. Based on that I'd rather have an FTL macro (or a few for different output types, different preferred formats like one line versus many lines, etc), and when that doesn't fit then do a custom template based on the data itself. > The last time I checked in on OpenTaps they seemed to be going in the > direction of ORM and DSL. Maybe there could be some lessons learned from that. Old habits die hard. I imagine that OpenTaps gets as much, or likely more, pressure to use "standard" technologies than OFBiz itself does. They have also had key developers from the very beginning that didn't like the patterns in the OFBiz Framework and they immediately started replacing it and writing new code using different tools. The result is quite an impressive pile of code and list of tools used (even larger than the amazingly bloated list for OFBiz!). For those who haven't spent much time developing with object-mapping-oriented tools and don't believe that they are more of a pain, by all means try a small project. Grab the JBoss Seam stack (for example) and try building the OFBiz Example application (the main parts of it anyway, not the various JS/etc demo screens that have been added more recently) with it (after reading the docs about recommended practices of course, make sure you know what they think of as a slick way to develop to be fair). I've worked with a number of people whose first exposure to enterprise app programming was with OFBiz and later had just such an experience, and the responses tend to be consistent in a way you can probably imagine. All of that said, now that Moqui is starting to take shape I find the OFBiz Framework to be cumbersome and inconsistent in many ways (things that are hard to fix, but that are not surprising given the pioneering history of the OFBiz Framework). Those funny quirky things are likely a turn-off to prospective developers and I'm hoping to remove that impediment to adopting the approach. -David
