Yep, [convert] exists in the sandbox and I've been moving forward with it in my usual way, which means I find a way to use it in some non-apache project of mine and just see how it goes. I've got it attached to two projects, but it's not being used in anger in them yet.
The code is based on the beanutils code, with a new lookup mechanism. I'm happy to mentor any further work on it, so you won't get abandoned without the ability to add patches etc. Hen On Mon, 19 Jan 2004, robert burrell donkin wrote: > hi ron > > IIRC there is a proto-project in the sandbox along these lines called > convert. convertutils (in beanutils) is ok but is handicapped by > backwards compatibility. it's been lacking momentum for some while but > it's might be easier to revive that project that create a new one. > > it's probably good that you don't have much code (just - hopefully - > enthusiasm) since that avoids any thorny questions of importing > external code. i'd suggest that you take a look at the convert project > and about ways to take it forward. then next phase would be writing > some patches and submitting them.
