Jasmin,
Thanks for the reply, but... I imagined that the error indicated a bad
data type, but I am using the Flash Builder plugin to find LCES
services and all the code was introspected and generated by the
plugin. As I mentioned in my post, I tried to use remoting and SOAP,
and in both cases I got a similar response.
Maybe the problem is in the code generation itself.
I tried to use SOAP from other environments and got the same result
with the create group/user. The sample code in QuickStarts is for C3
and tried similar code in Flex and got the same error. There seems to
be an issue on LCES side which does not recognize the data coming from
the call.
