class=MsoNormal>I'm working with an api that is somewhat dumb in one respect.&nbsp;
The method we call takes ~25 parameters.&nbsp; We send them as named parameters. One of
the parameters is of boolean type.&nbsp; What we've discovered from testing is that if
we send a value as either &quot;true&quot; or &quot;false&quot;, it acts as
if we sent &quot;true&quot;.&nbsp; If we construct the call without that parameter
entirely, it acts as if we sent &quot;false&quot;. I tried making it send null, but
that just causes it to fail at runtime.&nbsp; We presently have an &quot;if&quot;
for that one flag, with two calls to the method, one taking 25 parameters, the other taking
24.&nbsp; It is really obnoxious.</p></div><div><p class=MsoNormal><o:p>&nbsp;</o:p></p></div><div><p
