Flex 4 - Using RemoteObject And Multiple Components?

Aug 24, 2010

I was wondering what is considered to be a best practice when I have multiple components and use RemoteObject for AMF communication with a PHP backend.

Have the RemoteObject in the Main.mxml file with all the methods declared here (with handlers and all) and have all components call functions from the parentApplication, thus having a centralized result and fault handling, but making reusiability more difficult.Have a RemoteObject in each component with only the methods (and handlers) relevant to that component, thus making it easy to have clean, reusable components.

Flex :: Blazeds - RemoteObject - Handling Multiple Requests?

Jul 11, 2009

I have a couple of remote object methods that I want to respond to in different ways depending on the context, but I'd rather not set up a bunch of different RemoteObject aliases.Some background: Let's say I have an admin application that displays sales stats in different ways. The remote method looks like:

<mx:RemoteObject id="rpt" destination="AMFServer">
<mx:method name="getSalesStats" fault="getSalesStatsFault(event)"
result = "getSalesStatsSuccess(event)" />[code]........

The getSalesStats method takes an employee ID and a sales type as its arguments. You'd call it like:

rpt.getSalesStats(120, "peanuts");
public function getSalesStatsSuccess(e:ResultEvent):void {
salesdata:ArrayCollection = e.result.rows as ArrayCollection;[code]......

I'd like to pass something through the remote method to the responding function, like:

rpt.getSalesStats(120, "peanuts", "clicked button one");

but that of course throws an error because the server doesn't want that last argument.

Flex :: Oracle - Remoteobject Multiple Records In Database Of Same Info?

Feb 11, 2012

Case1: When a client makes a remoteObject request ie to save some Info... A call is made to Java SAVE_INFO method. If request failed ie came back to FaultHandler ( we save the info in an arrayCollection).Later we call SAVE_INFO again for each item in arrayCollection ie( if arrayCollection has 10 items.. We call 10 times the same method.. I know that's kind of stupid but we have no control over java to write a overloading method). Some times we see there are multiple records of same info in DB. I am not sure if this happens when looping over arraycollection and making calls or during normal one time call. We could not find a pattern to reproduce. Java LOG level is at Error level in production. can't set to INFO in production to monitor all calls. We dont know if this multiple times saved record is, the one in arrayCollection or normal one.

Flex3 RemoteObject --> WAS 6.1 , lCDS 3.0, Java1.5 --> Webservice -- > Java (hibernate) --> Oracle 10gCase2: When application is left open and user leaves for the day and submits info the following morning, we see duplicate records in DB of that info.(No arrayCollection here. Simple straight one call)Flex3 RemoteObject --> OC4J Blazeds Java1.5 (JDBC) --> Oracle 10g.Recently one of our Testers testing case 2 application found this pattern and I am starting to think that may be in the case 1 also.. users might be leaving for lunch/break and resubmitted the arrayCollection after coming back. During lunch java might have killed the sessions for the client and after resubmitting 10 at same time.

Flex :: Skinning Multiple UI Components?

Feb 2, 2011

Let's say you have a large number (N) of spark buttons in your app. Let's also say that your buttons all have very similar skins (size, various effects, etc) - the only difference being the specific png that they use as their BitmapImage. Do you end up with N skin files, all differing by 1 line? Or is there a smarter way to do this while not adding a lot of code when you create the buttons in MXML (in fact, ideally, none).

Flex :: Air - Implement Multiple View Components?

Aug 30, 2011

I'm developing a Flex/AIR application that's growing big, and some of the components need to be seen from different points of view (i.e Admin, Staff, User, Guest). I've seen myself placing code in those components to handle what the user can and can't see. But it's becoming unmanageable as the code and the roles grow bigger. I was wondering what's the best way to implement multiple views inside the components while keeping them as reusable as possible.

What I'm doing right now:

<mx:HBox width="100%" horizontalAlign="right" visible="{_view == TS_VIEW || _view == PRJ_VIEW}"
includeInLayout="{_view == TS_VIEW || _view == PRJ_VIEW}">
<mx:Button label="Agregar" click="button1_clickHandler(event)"
enabled="{_state != ADDING_STATE && !_loading && _canAdd}"/>
</mx:HBox>

Flex :: Flash Builder: Embedding The Same Asset In Multiple Components?

Flex :: Structure Multiple Cairngorm MVC Projects That Share Several Components?

Jun 5, 2009

I recently completed a project for a custom report UI in Flex. Now, I've been tasked with creating a new application that is essentially a "lite" version of the original UI. It will include only a few of the options that are in the original application. Also, it needs to be a separate application.

I do not want to duplicate my code, so I am planning on moving a bunch of the classes from the original application to a new library that can be shared by both applications. However, I'm trying to figure out how to make this work in my MVC environment.

For example, I have an Accordion component that lets users filter several items. Each Accordion child is an instance of a custom component with two lists (one for entities available for selection, the other for the entities the user has selected). Each child component has properties bound to the Model and functions that call Cairngorm Events.[code]...

Flex :: RemoteObject Synchronous Call?

Oct 1, 2009

In the code below when I call chkAuthentication function from another function the remoteObj.login (login function in my service file (.php)) is called after the remaining code in that function. i.e., the loginStatus is returned from the function before the result-handler function loginResult is called. but my loginStatus is supposed to be set in loginResult function. It seems that the asynchronous behaviour is the culprit. what should I do in order to get the loginResult function to complete first?

Actionscript :: Flex RemoteObject Timeouts?

Oct 21, 2009

I've been tinkering around with Flex RemoteObjects, and I've found that they aren't very well behaved with respect to timing out.First, I can't figure out how to set a timeout on "connect". I know I can set requstTimeout, which will correctly timeout after an initial handshake... But if the server doesn't handshake, the connection doesn't time out (eg, the server accepts the connection, then does nothing with it, the client will just be left hanging).

Second, when a requestTimeout fires (timing out the request), Flex doesn't actually take any steps to tear down the connection - it just leaves it hanging there (no RST or the like). Clearly, this is more than a little bit undesirable. Is there any way to explicitly tear down the connection after the timeout?

Flex :: Get The Result Of A RemoteObject Immediately?

Apr 29, 2011

I need to make a function that execute a java method and return his result. It is static becouse a lot of other functions will call this function. So I did this:

var jRemote:RemoteObject = new RemoteObject();
var s:String;

But the function returns null, because the valresult() was not been called at the end of main function. What shoud I do to make FKDescription() return the string that came from remoteobject?

ActionScript :: Flex - RemoteObject Response Headers?

Jun 16, 2009

I am in the process of writing an application in Flex 3.3, using the Cairngorm framework, for deployment as an AIR application. The application heavily utilizes RemoteObject services to get data from a web server.Each of my service delegates extends a common class which provides a method for calling service methods on the RemoteObject.So, where I previously usedServiceLocator.getInstance().getRemoteObject('myService').myOperation.send();I instead usethis.send('myOperation', 'myService');I use this method instead of calling the RemoteObject operations directly because this method adds another, global, responder to the operation call. This extra responder analyses data in the headers of reponse from the server.

Or at least it should -- this is where the problem is. In the result data (event as mx.rpc.events.ResultEvent) the headers property is always null despite the headers definitely being sent from the server.

Flex :: RemoteObject Inconsistent Channel Location?

Jul 1, 2009

I have a swf which, for some reason, has four RemoteObjects pointing to the same ChannelId, but they are listing that channel as being at two different spots. In four of the five RemoteObjects, everything behaves as expected, but in the fourth (WidgetService), the version on dev is switching from dev.context.root toloc.context.root. To make matters more confusing, it only does this on the dev server (QA and production are fine, as are local builds).The relevant information from the config files follows:

#This is from build.properties, which is used by Ant
#to build the swf on the server
flex.sdk.dir = /path/to/sdk/flex_sdk_3.2.0.3958

Flex :: Prevent RemoteObject From Batching AMF Messages Together?

Jan 10, 2010

I am using Google AppEngine, in conjunction with PyAMF to provide RemoteObject support. In my Flex code I make several RemoteObject method calls at once which tends to batch the AMF Messages into a single HTTP request. Most of the time this is fine but AppEngine applies some strict per request limits (in this case I am hitting a DeadlineExceededError - max 30 seconds). A number of service methods are expected to take upwards of 10 seconds and if these are batched by the RemoteObject into 1 HTTP you see where this is going. Now you could say refactor your service calls and that is also going on but not really the question being asked here. Is there a way to prevent Flex RemoteObject from batching AMF requests for situations like this? I have done a fair amount of Googling on the subject and come up with bupkis. It seems to me that I would need to implement a custom version of mx.messaging.channels.AMFChannel or something of that nature, which seems waay too hardcore for a feature like this

Flex :: RemoteObject Intermittently Failing To Invoke CFC

Jun 10, 2010

I have a Flex app that uses Flash Remoting and the RemoteObject to pull data from a ColdFusion CFC. About 75% of the time it works, but the other times I get a message using Charles (a debugging tool) that says faultString = "Unable to Invoke CFC". FaultCode = "Server.Processing".

Here's my RemoteObject:

<mx:RemoteObject id="carsSvc" destination="ColdFusion" source="ca.sqmIDash.cfc.sqmIdash">
<mx:method name="getCARs" result="resultHandler(event)"/>
</mx:RemoteObject>

The server set up on our web farm is to use load balancing. I'm not sure if this is causing the problem or not. Probably not, but it's a thought.

Flex :: RemoteObject After Application Built - No Fault No Result

Jan 25, 2011

When i run it in Flash Builder (debug mode) the remote object called successfully. but whenever i build the application (AIR application), then the remote object will return no result nor fault, the busy cursor is showing about 3 seconds. then no clue at all. how to get advance fault or something than regular fault event or result event? or anyone have the same experience?

UPDATE: Actually it was failed only for ONE service method, for other method (some of them took longer time to call) the service call is work fine. CASE SOLVED So the problem was not on the service call, but on my result conversion that cause the advanced datagrid failed to render.
