I couldn't find any utility method to only copy non-null properties from the form bean.
I tried your suggestion to describe() the formbean then filter out the nulls, then populate() the destination formbean. That worked for formbeans which do not have nested indexed formbeans. A describe() of the nested formbean collection puts the toString() representation of the Collection into the Map, thus losing the collection object. So finally, I created a mergeBean(srcBean, destBean) method to copy non-null properties and call a similar mergeBean() on each of the nested formbeans.

For what it's worth, I think I just realized I need to solve the same problem, so I'll try and remember to post here if I come up with a nice solution. If you get anything from commons-user drop me a note ;-) L. -- Laurie, Open Source advocate, Java geek and novice blogger: http://www.holoweb.net/laurie --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- The contents of this e-mail are intended for the named addressee only.
