Title: Re: [flexcoders] Re: WSDLError:Element not resolvable => LoadEvent doesn't imply service ready

Hey Sahlas – actually the only test for a correctly loaded wsdl is the canLoadWSDL property. If this fails it is back to the drawing board.

As for a publicly accessible wsdl try my server http://www.ifeel3.com/webservices/services.asmx?WDSL  - there is a complex type under the function “doQuery” if interested. If you go to the same address minus the ?WSDL then you can see all the operations and the parameters out/in etc.

Samuel

Howdy,
 
I’d like to reproduce this internally here in the FDS QA lab using some of your examples.  Can someone on this list forward me a link to a WSDL that is publicly accessible with sample code to execute?
 
Thanks, Bill

Hi Kaleb,
 
Cool! Great stuff.
 
My guess is that the delay is machine dependent, but not necessarily network dependent. I do believe that the LOAD event does indicate that the WSDL actually has loaded successfully. Flex will not need any more access to the network in order to initialize the web service.
 
Anyway, it’s a little bit sloppy that the LOAD event does not indicate that the webservice is actually ready for use. I consider this a bug if you ask me. So, maybe this is something we can put on the wish list???
 
Thanks,
Franck

Frank,

I did a bit more research into this. I don't need nearly a second
for the WebService to be ready after the load event. I just put the
whole process in a loop to see what kind of delay I need to make it
work on my box (with the service running on my box). Unfortunately,
the delay is probably machine and network dependent and, therefore,
would have to be different on other machines.

My results were:

res[delay in ms] = # successes (out of 100)
res[1] = 0
res[2] = 5 ...
res[10] = 13 ...
res[15] = 42 ...
res[20] = 53 ...
res[30] = 77 ...
res[38] = 100
(and the rest were 100 also)

Somebody else had what may have been a similar problem and he just
re-fired the request
(http://groups.yahoo.com/group/flexcoders/message/46401). That's
certainly not an elegant solution....

So, I still don't have a solution, just a work-around. Does anybody
else have any ideas or suggestions?

Thanks.
