RE: [flexcoders] Difference between WebService and Remote Object

Thu, 09 Feb 2006 02:48:12 -0800

Hi
 
i manage to find the problem to at least one of the cases that we had trouble with.
 
1. RO result that was sent right back to the server and failed  - this problem was solved , it caused by a Public Static final variable in the Java class therefore Flex thought it is a different object.
 
2. RO result that was set as the dataProvider to a datagrid and then pulled out from the grid and sent back to server - i didn't managed to find the problem here .
only creating the object from scratch - does the dataProvider changes the objects it gets ??
 
thanks

I've already tried this and even Object Copy.
 
 
I think you don't understand the problem ,the returned object is good , BUT when sending the same returned object to server i get convertion error.
 
Attached are the two VOs that participate in this.

I'm not sure that I understand the problem.  Is there anyway you can post the value object definitions?

The public static final member "may" be causing a problem.

I noticed this line of code may also be the problem.
var userVO:UserVO = event.result;

try this instead
var userVO:UserVO = UserVO(event.result);
if(userVO == null)  trace("Error: the cast failed");

How , i create the VO using Ant task (code generation)
except for 1  public static final member - could that be the diff ?

More than likely the definitions for your java UserVO  and your ActionScript UserVO are different.

Hi
 
 
while testing the performance of our application , i changed the way we work with the server from WS to RemoteObjects
i found that there is a difference in the way data is being received / transmitted although we use the registerClass (as the POJO2AS does for you) .
for example a method that was saving user info to DB did not work with RO - saying it could not convert ASObject to typed object.
 
what is wrong here ?
 
here is a short snapshot
 
 
<mx:RemoteObject id="service">
    <mx:method result="getUser(event)>
    <mx:method result="saveUser>
</mx:RemoteObject>
 
function sendRequest(){
 
    service.getUser(111);
}
 
function getUser(event){
    var userVO:UserVO = event.result;
 
    // we save with the save object we got.
    saveUser(userVO);
}
 
function saveUser(userVO){
    service.saveUser(userVO);  ///fails to convert ASobject to typed object
}
