<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a way using the ‘from’ constraint to
get
the values of a map(the implementations of java.lang.Map eg HashMap,
TreeMap,
etc) into a constraint parameter, and if so can someone please give an
example.
Below is the way I’ve been trying, without success, to get a value
based
on a key.</p>

We support MVEL notation for the 'from' keyword.<br>
