Sorry for the radio silence! I've been really short of time lately so i am a bit ashamed to say i have not tried the solution that Bruno proposed yet (the solution in Amila's blog). Nevertheless i did try what Deepal suggested and it sure did the trick :D (i was waiting to try both before replying)
I still want to try the other approach since it seems to me that such solution provides more control over the web service invocation, however, being a newbie i'm not very sure which aspect of the web service invocation i want to control exactly nor how... Anyway, i guess it depends on the complexity that we want to achieve Thank you all and sorry for taking so long!
