Hi,

while I'm at it... The reason that I actually stumbled across this was that I
was trying to append the properties of a bean to the link parameters.
Now I'm curious whether it would be possible to extend the functionality of
RequestUtils to also handle this case.
I've attached a diff that should illustrate this and so far seems to work for
me. (Although I'm not sure about the exception handling.)
Have a nice day
