Hi Cumhur,
indees the problem is Flash Player's single threaded engine. If you setup afor
or while loop after calling a remote method, the player "blocks" and is not
able to process responses that comes in from the remote method.
To process the result of a async method invokation, you'll have to use the
result/fault events of your service tag, i.e.
public function testEndToEnd() {
_root.logonWindow.username.text = "tcfeu";
_root.logonWindow.password.text = "1";
EventBroadcaster.getInstance().broadcastEvent("SomeCommand");
}
after the event has been broadcasted and SomeCommand executed, some time later
the defined onResult event handler will be invoked with the service results (if
SomeCommand implements Responder then SomeCommand.onResult() will be invoked).
If an error occured, the onFault method will be called.
Hope that helps,
Dirk.

Subject: [flexcoders] Asynchrony problem?
Hi folks,
We are using cairngorm 0.9 version and and flexunit.
We would like to create a testcase which initially setting the input valuesup
and then broadcasting an event
that is creating a web service call at back-end, processing it resulting output
from web service and updating the view.
Finally, we would like to test updated view object values against the expected
values we know before.
We have created the test case given below.
(1), (2) sets the input values for test view.
(3) submits the command
(4)(5) waits for asynchronous web service call to finish. (2000 millisecond)
(6) logger to localconnection
(7) assertion
This test is failing, however it is supposed to pass based on the Logs and
execution values supplied.
It seems although we force this test method to stay in idle loop for 2000
milliseconds, web service call is not finished off by the mean time.
(I increased the time, it did not work)
It seems problem is rooted to flash player single-threaded implementation,
So would you guys recommend any workaround to overcome this asynchrony problem
or something else?
Any help will be appreciated.
Code piece is given below.
public function testEndToEnd() {
_root.logonWindow.username.text = "tcfeu"; (1)
_root.logonWindow.password.text = "1"; (2)
EventBroadcaster.getInstance().broadcastEvent("SomeCommand");(3)
var timer:Timer = new Timer();(4)
while (!timer.wait(2000)); (5)
Log.debug("SystemTests testEndToEnd() method has been called"); (6)
assertEquals( "return value is different than expected " ,
"value" ,
valueReturningFromWebServiceCall ); (7)
}
