Hi Niall, Thanks for the reply! Apparantly this problem is quite difficult to get answer upon. You're the only one until now.
Well, I was getting different exception in different scenario. - When I put an array initialization (someWrappers = )in myForm's default constructor, I would get Array Out Of Bound exceptions. - When I don't do an array initialization for myForm (on REQUEST scope), I would get a method invocation exception from BeanUtils.poulate() due to some getter property descriptor that can't be found. (?) But I have declared all my getters and setters (see fot your self below). I checked my generated HTML sources (from JSP), but they are all rendered as expected. That is, like you have specified below. Weird, huh? When I chang my scope to session... it seems to work. But I don't want my form in sessin scope. (And if this is working indeed in session scope.... why not for requests scope?) The solution that you propose... I have seen it too on the internet. But this solution does not guarantee the right order of the array elements. And order IS a Requirement for my problem area. Any hints?

Your jsp should be generating the following? <input type=".." name="someWrapper[0].propA" ...> <input type=".." name="someWrapper[1].propA" ...> BeanUtils will try and access the indexed getter - getSomeWrapper(0) and then call setPropA(...) - presumably its one of these methods ist having problems with? Anyway the problem usually with request scope beans is that when it calls the getSomeWrapper(index) method the array isn't initialized and it returns null - if you put logic to "automatically" grow your array in the getSomeWrapper(index) method then it should solve this.
