Obviously that's not valid, but pretend it would work, I need to write
*real* code that *will* work to do the equivalent of that. I haven't seen
anything in BeanUtils that would do it, hoping I'm missing something.
Could you perhaps explain what is the problem with the above ? Perhaps
you could provide some (pseudo, hypothetical) code using BeanUtils
that shows how you would do what you want to do ?
I can certainly explain why the above isn't valid... myArray is private
in myBean, so I can't do the above because I simply don't have access to
that field. If it was public then the above would work fine and I
wouldn't have a question :)
The use case here is specifically for the DependencyFilter I add in Java
Web Parts... basically, I'm instantiating a class based on a config
file, and then configuring it (rudimentary IoC)... It already handles
simple properties, Lists and Maps no problem, but arrays seemingly are a
little trickier (and maybe I'm wrong about that to begin with) because
of one thing I want to do: I don't want to force the class to have to
create the array itself. I want to be able to have a list of values in
the config file and create the array based on the number of elements,
which of course could vary. So, I won't know the array size until the
object is created.
Does that make sense?
