Accessing returned objects

[Ronald Wernecke]

I have a little project, displaying and processing data from a webshop.

I got stuck, because I oversee something. As more I look, the less I see

If have this declaration:

Code: [Select]

<productsservice:ProductsService id="productsService" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true"/>
<s:CallResponder id="userLoginResult" fault="Alert.show('Anmeldung ist fehlgeschlagen','Systemmeldung')" result="login_result(userLoginResult)"/>
<s:CallResponder id="articleSearchResult" fault="Alert.show('Abfrage ist fehlgeschlagen\n'+event.fault.faultDetail,'Fehlermeldung')" result="listResult(articleSearchResult)" />
<s:CallResponder id="getProductDetailsResult" fault="Alert.show('Abfrage ist fehlgeschlagen\n'+event.fault.faultDetail,'Fehlermeldung')" result="displayProduct(getProductDetailsResult)"/>

the first two work perfectly as expected.
But the displayProduct function is never called.

If I watch this in Charles, data is received as expected, but never displayed.
The debugger does not want to communicate, which does not make it easyer.

Code: [Select]

getProductDetailsResult.lastResult.data.products_ean
this passes the compiler ok, but never receives any data, even though the data is there (as Charles says).

when the things gone to fast, i generally use a setTimeOut function, it generally help the flash player in some cases.

very weird indeed !

did you get this solved? what does your displayProduct function look like?

[Ronald Wernecke]

I striped the function down to only show a message box.
It is not even called.

Accessing the lastResult ends in empty values, even though I see the values in Charles exactly as expected.

Code: [Select]

protected function displayProduct(p:CallResponder):void{
//Alert.show(p.lastResult.data.products_price,"Preisinfo");
//this.productDetail=p.lastResult.data;
//Alert.show(this.productDetail.products_name,"Debuginfo");
Alert.show("Daten empfangen","Debug");
}

and the result screen of Charles delivers:

Code: [Select]

body Object
data Object
err Integer 0
msg String 1 Datensätze gefunden.
Data opened:

Code: [Select]

products_id String 3334
products_ean String 8436032420035
products_quantity String 9
products_shippingtime String 1
products_model String OCC-13600
...

still hard to see

where are you calling your send()?

are you using httpservice anywhere?

[Ronald Wernecke]

It is called, when you click into a datagrid:

<mx:DataGrid id="productList" x="10" y="173" width="555" height="284" editable="false" click="getProductDetails(productList.selectedItem.products_id)">

Code: [Select]

protected function getProductDetails(pid:int):void{
Alert.show("Nach Artikel "+pid+" wird gesucht","Info");
getProductDetailsResult.token = productsService.getProductDetails(pid);
selector.selectedItem=productDetails;
}

This function is definately called, because the selector (its a tabbed controll) changes, and as I mentioned, Charles does deliver the expected data.

[kofi addaquay]

yes its being called one way...and not returning..

not sure...the first thing that comes to mind is your result handler function displayProduct..because that is what gets fired when data comes to flex

the function taking a parameter p of type CallResponder (p:CallResponder). i think this is wrong:) it should be ResultEvent. did you try that?

[Ronald Wernecke]

I tried this - it definately delivers a object of the type mx.rpc:CallResponder

Error message says - cannot convert CallResponder to incompatible ResultEvent

And the other services work, which are written the same way.

The call itself works - I can see the result in Charles

[kofi addaquay]

Hmm... have you tried skipping mxml entirely for that one service and using actionscript instead?

have you used the ItemResponder and AsynToken method to try and solve this problem?

[Ronald Wernecke]

Nope - i have hoped, you can see a typo, i didnt find
I can't think of anything else, because the other routines are working perfectly.

But I think, I have to reinstall Flex, to make the debugger running.
This is the last chance to find the bug.

Sure, it might be even better to encapsulate the service calls in a AS-Class.

[kofi addaquay]

yes i hate it when things like that happen

you know very well that it should work...but it doesnt. try the actionscript way. if it doesnt work... you can try your reinstall. let me know if you need help in the ItemResponder and AsynToken way of doing it. But you should be able to do it easy !

[Ronald Wernecke]

you are right - I got lost in all these new classes
It looks, like they over complicated some simple things.
I got to get deeper into these classes.
Most examples use combinations of MXML and AS, which seam to make trouble in my case.
