Can you please attach your php files(samples will do) which are not working.
Here is a the actual php class:
$r = array("r"=>"s","t"=>11230,"wr"=>500);
This class has a defined return VO(questionDetails) in flex. It is recognized in the IDE, but when I run the app, I always get a "null object reference" error. I can't seem to convert the result to questionDetails, and I can't access the fields as properties or part of an array of the return object as an instance of "Object".
If this helps. I usually don't use value objects, for various reasons. I set a new object for the token result, then get my data from that object. I always have Network Monitor on so that I can look at what FB is sending to php(request) and what php is sending to FB(return). The return info in network mon usually gives me a good clue if the problem is in php or FB.
Also, if you have your complete php class shown, you should include an error message returned if php/sql has a problem. This will show in Network Montior's result.
