[flexcomponents] CF file doing SQL SELECT but error accour only when no results are found

[elad_nyc]

I am building an application and trying to validate user name and 
password however when CF doesn't find results it creating an error 
message "Unable to invoke CFC".

I was trying to use the "try" & "catch" to a void a bug in the script 
but no luck. any idea?

try {
    cfService.getQuery(UserName,Password);
}
catch (error:Error) {                              
    trace("<< Error >> " + error);
}
