View 7 RepliesJust want to clear a very basic doubt am having for quite some time.
Is LCDS and FDS the same
I've heard somewhere that LCDS is no longer baked in into CF9, and LCDS Express will be phased out, is that true?
If I were to start a new CF8.01 + LCDS Express 2.6 project, what are the risks? Should I abandon that plan and go for BlazeDS instead?
In my project, I use LCDS to define a holiday table which contain holidayId, countryCode and companyCode. LCDS generated all the getBy which are very handy. However, I need to get the records which are having countryCode = US AND companyCode = ABC. Surely I cannot use any of those generated getBy (each of them deals with a single field only). Can you suggest me how to modify the code in generated services (in my case, it is _Super_HolidayService.as) to handle multi-key data retrieval
View 1 RepliesI'm trying to find the IP address of a client when they make a particular LCDS service call. Understanding all the issues of getting a "real" IP address and privacy concerns and so on, it is possible to find the client's IP address?
View 3 RepliesI have an LCDS server sitting behind a corporate proxy/firewall. I need to use a configured HTTPProxyService on the LCDS server to make requests out to beyond the firewall (can't go directly from the client because of crossdomain.xml issues) How do I configure LCDS to use the corporate proxy on it's outbound requests?
View 2 RepliesI have a POJO which declares a collection of List<Long>.
We're currently sending an ArrayCollection of Number, and it's arriving at the client as an ArrayCollection, populated with IntegersGiven the issues with Type Erasure & generics I understand how this is happening. How do I fix it?
Unfortunately because of some internal limitations, the model cannot be changed. Ie - we can't use a subtype, and we can't implement IExternalizable.Are there other options for registering custom type converters in LCDS, other than IExternalizable? Alternatively, are there any annotations we can use that indicate the type to be used for a collection?
I'm trying to serialize an object which has an InputStream. I need it to arrive on the flex client as a ByteArray.
[Code]...
I've set breakpoints in this code, and I see it being called as expected. However when the object arrives on the client, the input stream is typed as Object, and it contains no properties. What am I doing wrong?
Can i learn Flex without learning ActionScript 3?

View 1 RepliesWould be of amjor benifit to learn the AS3 structure by way of Flex for the next verison of Flash? What I mean is, will Flash 9's AS be AS3 such as it is in Flex... and if so, would it be wise for me to familiarize myself with Flex's way of coding for that very reason?
View 5 RepliesI'm developing a Flex application using RobotLegs, LiveCycle DS & Java.I'm trying to implement an update function, using LCDS, but I'm running into some strange behaviour:This is the ActionScript code within a RobotLegs' execute command, used to perform the update:

I'm developing a web application (client in Flash Builder 4, server in Eclipse 3.6 + Tomcat 7 + Spring 3 Framework). How do I make the Flex client automatically deploy in the Tomcat server and use BlazeDS messaging and remoting more seamlessly?
View 14 RepliesWe recently built a new dev server for flex builder and installed coldfusion 8. We currently have everything working on our old server using coldfusion 7. We copied the services-config.xml and our project over to the new server. It compiled fine, I updated all references to the new server. When I try to run the flex application I receive the following error:
Warning: Failed to load policy file from http://localhost/crossdomain.xml
* Security Sandbox Violation *
Connection to http://localhost/flex2gateway/ halted - not permitted from file://ourServer/folder/ourProject/bin-debug/ourProject.swf
We created a valid crossdomain.xml file on the localhost (which I wouldnt think would be necessary since everything is on the same server)
Am facing issue with session timeout. Say for instance, the user logs into the application and he waits for 30 mins (session timeout time) and then tries to get a service through remote object.Ideally speaking, since the session has timeout the user shouldn't be able to hit the remote object, but this is happening the other way round.

The question says it. Does anybody know the answer to this? We're running into problems when 3rd-party cookies are disabled.
View 1 RepliesI have Flex front end talking with ColdFusion as the back end. I have to debug my application and need to: Add log support to ColdFusion where I can add my custom messages to log list.Access this log at Flex end.Is it possible? Has anyone tried it before?
View 1 RepliesSo basically what I'm trying to do is make something like this:[URL]... I've searched long and hard to find a site that would show me some pseudocode (at least) or an algorithm as to how to implement this type of application. But everything I find are only applications that take in data and do all the work for me to create the graph. I need to actually create it for myself, just a simple one for now. Does anyone know where I can find this? What I want it to do is take data from a database and use it to create the treemap, then express it in a GUI like in the link above. If any specifics are needed I can provide it. I'm trying to do this in Flash Builder using Flex and using ColdFusion as the backend.
View 1 RepliesI'm using CF to retrieve values from a database that are then being stored in a datagrid in Flex. I then want to selectively take the value from one cell of the datagrid and store it as a string variable. I've searched around, but I haven't been able to come about a solution. The users will not be interacting at all with the datagrid as it will be hidden to them.
View 1 RepliesIs the same possible in ColdFusion? Currently I am using .Net/Fluorine to return objects to the client. Whilst in testing I like to pass strings representing the select statement and the custom object I wish to have returned from my service. Fluorine has a class ASObject to which you can set the var 'typeName'; which works great.
I am hoping that this is possible in Coldfusion. Does anyone know whether you can set the type of the returned object in a similar way. This is especially helpful with large collections as the flash player will convert them to a local object of the same name thus saving interating over the collection to convert the objects to a particular custom object.

I'm calling ColdFusion cfc method using RemoteObject method of the Flex.
[Code].....
So you can see that I changed the sequence of the parameter, when I call the cfc method. But it does not worked. It means that <s:arguments> does not pass the named parameter. Is there any solution for that? As you can see that I may have some of the arguments not mandatory so, it must be passed by name.
I have a Flex/CF app that sits on 2 redundant servers behind a load balancer. Both the Flex and CF side make calls to the same CFC. The Flex, CF and CFC are all in the same folder. When the CF code calls the CFC, there's not a problem. However, when the Flex code calls the CFC, it adds an explicit port "84" to the URL.This causes a problem for the load balancer which only accepts traffic from port 80. As I understand it, the load balancer would internally route requests from port 80 to 1 of the 2 servers on port 84 (but that internal routing should be invisible to the client).

Inside a flex app, I have a user login. The login calls a ColdFusion function as a remote object which authenticates the user and, if applicable, returns their id and access level. This works fine, but now I'm at the point where I want to also create a cookie for another ColdFusion template (called from fileReference.upload()) to be able to access later. I have tried several different methods for creating the cookie -- cfcookie, creating a cookie with JavaScript inside the ColdFusion function, and creating the cookie with JavaScript with an external interface once the coldfusion function returns to the flex result handler. All of these have been tried with a plethora of options regarding expiration, path, and domain tags.

I have a scheduling application that allows users to save any changes. When the user clicks the save button, Flex sends all the information to a coldfusion script which picks the information apart and sends saves it to the database. That all works well and good, but I would like to be able to display some sort of text to the user saying something like "Your file was successfully saved" or "There has been an error.

Is it easy to implement Flex Ajax Bridge with ColdFusion? Where can I learn how to use it? My frontend is pure HTML+JS and I just need the push capability. I thought of using Websocket Event Gateway and Server Sent Event (aka EventSource) but seems like they don't have much browser support quite yet. Any pure jQuery short/long polling option Any good Server Sent Event polyfill solution available for older browsers?
View 3 RepliesAssuming calling the same ColdFusion web service and all other factors are identical, is there a difference in performance/speed between using the following two tags?
<s:RemoteObject id="MyService" destination="ColdFusion" source="MyWSFolder.MyService"/>
and
<s:WebService id="MyService" wsdl="http://www.myDomain.com/MyWSFolder/MyService.cfc?wsdl"/>
I hope this problem would not waste your time. I use Adobe Coldfusion 9 to create CFC to to interact with database. Generally, CFC can be generate WSDL by itself. for example:[URL]..
The WSDL was generated well. But the problem has been found when I tried to use Adobe Flash Builder 4's Data service to generate service class to connect ColdFusion's WSDL.
If you tried to invoked the remote function that return primitive data type as int or String, it works correctly.

I'm trying to make a Flex-based desktop application consume messages from an ActiveMQ topic with a durable subscription, using the JMS bridge of BlazeDS. The basic scenario is as follows: Messages are produced by other producers in the topic to which the Flex client is subscribed. The Flex client may go offline from time to time, but it must receive all the messages it has missed while being offline when it connects to BlazeDS again. (Of course the Flex client connects with the same client ID every time). It can not be guaranteed that the Flex client is shut down gracefully.
Everything works fine if I explicitly disconnect my consumer on the Flex side by calling disconnect() - I do it in the exit handler of the application. However, due to #3 above, it is not guaranteed that disconnect() is called all the time. When the Flex client shuts down without calling disconnect(), it seems that the subscription of the "proxy JMS client" that BlazeDS creates and associates to the Flex client stays active towards ActiveMQ, so ActiveMQ still thinks that the client is logged in. When the Flex app starts up the next time, it is unable to log in to BlazeDS because ActiveMQ refuses its subscription, claiming that the client ID is already taken. Why is it so and what can I do here to ensure that BlazeDS makes the "proxy JMS client" offline in ActiveMQ when its real Flex counterpart terminates unexpectedly?

I am trying to build a portfolio application similar to the used by Whitevoid. I am using Flex 4 and Papervision3D 2. I have everything working except for one issue. When I try to load an external SWF as a material on one of the planes, I can see any native Flex or Flash components in their correct positions, but the papervision objects are not being rendered properly. It looks like the viewport is not being set in the nested swf. I have posted my code for loading the swf below.
private function loadMovie(path:String=""):void
{
loader = new Loader();
request = new URLRequest(path);
[Code]....
Below I have posted two pictures. The first is a shot of the application running by itself. The second is the application as a MovieMaterial on a Plane. You can see how the button created as a spark object in the mxml stays in the correct position, but papervision sphere (which is rotating) is in the wrong location.
