I believe the solution Dirk provided solves this problem as well.
That is, in addition to Mehdi's initial solution #2:
> > > remoteObject.cfFunction ( toPass, true );
You can use named argument syntax:
remoteObject.cfFunction({arg1:toPass});
Where arg1 is also the name of the argument in the CFC method "cfFunction".
Mohanraj, this is the solution I posted in my blog:
http://tomlink.net/blog/index.cfm?mode=entry&entry=BBFE84D5-7E97-A3B0-EE0B2D
C292F5272F, where you also posed this question. Please correct me if I am
missing something.
