Chris Poulsen commented on TAP5-2596:
-------------------------------------
If you have special needs then roll your own components and possibly use them
to override the built-in counterparts, we have heavily customized grid, tree
and a bastard tree table (combination) at work, that fits our needs, but I
seriously doubt that their extensions will fit everyone else. We do not
override the built in components, but maintain a somewhat close API
compatibility, so we can swap in one of the tapestry versions without too much
hassle.
I think many of the parts of tapestry are designed to be sufficient for basic
use and made possible to override for more specialized stuff - IMO a nice and
flexible way.
When you start thinking about how such a grid component should be designed to
meet the requirements of everyone, you have started down the rabbit hole.
