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:

public static function FKDescription(dest:String):String{
var jRemote:RemoteObject = new RemoteObject();
var s:String;

[Code].....

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?

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.

Flex :: Why Wouldn't A Flex Remoteobject Be Able To Work Within A Custom Component

Mar 31, 2010

I have a remoteobject within my main.mxml.I can call a function on the service from an init() function on my main.mxml, and my java debugger triggers a breakpoint.When I move the remoteobject declaration and function call into a custom component (that is declared within main.mxml), the remote function on java-side no longer gets called, no breakpoints triggered, no errors, silence.[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 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.

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 :: 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 :: Abort/stop A RemoteObject Method Call?

Feb 27, 2012

I am using RemoteObjects to call ZendAMF PHP from Flex/Flash Builder 4.6. I want to stop or abort a method call before it sends the request to the server based on an event or similar.

I have a class where I create and store all the RemoteObjects - for example:

activityLogService = new RemoteObject("zend");
activityLogService.endpoint=endpointServer;
activityLogService.addEventListener(FaultEvent.FAULT,faultHandler);

Then later I can simply call this object:

remotingService.activityLogService .getRecords();

I am trying to find a way in my remotingService object to stop the request - and not send anything to the server - for example if some variables are not set properly.

I noticed there is an invoke event: activityLogService.addEventListener(InvokeEvent.INVOKE,invokeHandler);

However, I can not tell if that's going to stop things at the proper point, or if it's even possible to actually STOP the request - if so, how?

Flex :: Air - Dialog Not Display Immediately?

Sep 11, 2009

In an AIR application I have the following code:

theDialog = PopUpManager.createPopUp( this, TheDialogClass, true ) as TheDialogClass;
theDialog.addEventListener(FlexEvent.CREATION_COMPLETE, cpuIntensiveCalc);

At the end of cpuIntensiveCalc the dialog is removed. The dialog informs the user that "something is going on, please stand by."

The problem is that cpuIntensiveCalc starts before the dialog draws. So the user experience is that the application freezes for 10 seconds with no indicator, then the modal dialog flashes quickly (less than a second) on screen.

The Adobe docs say this about creation_complete

Dispatched when the component has finished its construction, property processing, measuring, layout, and drawing.

So this feels like the correct event. In the name of completeness, I also tried

theDialog = PopUpManager.createPopUp( this, TheDialogClass, true ) as TheDialogClass;
cpuIntensiveCalc();

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 :: Force 'updatedisplaylist' Immediately Rather Than At Later Some Point?

In flex component life cycle, after we make some change in a components property, invalidation methods schedules a call to methods like commitProperties, updateDisplayList, etc for some later time. I need to call the updateDisplayList instantaneously. Is there some direct way to do this.

Currently, both the labels are changed simultaneously after completion of the loop.

I know, it is elastic race track issue, but isn't there some way to achieve this ?[code]...

Flex :: Reference An Entry Immediately After It's Been Added To A DataGrid

Aug 14, 2009

I have a drag-and-drop event form in a flex project. I need to run a validator right after the item is dragged into the dataGrid. In it, I fire off a function through dragDrop="verifyEventUsers()". In the validator, I compare the contents of the two arrayCollections, but it appears to be running the checks prior to completion of the drop. For instance, if I drag an element into the dataGrid and trace eventUsers.length inside the validator, I get zero. When I drag the second element, it traces as one even though two lines now appear.

How can I set up a validation script that runs after the drag-drop action has finished?

Flex :: Unable To Refresh Tree Control With New Branches From Successful RemoteObject Call

Feb 2, 2010

I'm trying to populate a mx:tree component with values that I'm getting from BlazeDS. The returned data from BlazeDS is fine it's an ArrayCollection of Folder value objects.I've been instructed to use Cairngorm for this project. I'm pretty new to Flex and Cairngorm. According to the limited documentation that I've read online I should populate the model with data so I've stuck the array collection there.What I'm stuck with is trying to update the tree component. I feel that I need some way to notify the container component for the tree that the data (i.e. the subfolders) is available on the model. I was hoping that it would be possible to fire a function in the container component to add the subfolders as children of the selected node (I could chuck this on the model before the remote object call I guess) then fire tree.invalidateList() and tree.validateNow(). Any ideas?
