Flex :: Check For Nil 'true' Value On XML That Is Passed Back From Webservice Call?
Sep 27, 2011
I am receiving xml from a webservice call that contains a nil="true":[code]I used the Flex DataService (webservice) wizard to create the service objects for the cacheEntry component. This object will be serialized later on a different webservice call and stored in a database.I set a breakpoint on the set SystemFK method in the service object. It appears that the value passed in was an empty string!Allowing this value to be an empty string will cause problems in the webservice implementation in Java on the other side. Since the database value was null it is expecting a null in return, If I avoid setting this value, the serviceObject should send back a null which will make the database happy.How can I detect that a nil = true is present in the XML in order to avoid setting this value?
So, there are a wealth of Flex articles online about how to handle a .NET WebMethod that returns a DataSet or DataTable. Here is an example: Handling web service results that contain .NET DataSets or DataTables So, I know how to use result.Tables.<tablename>.Rows and the like. But what I cannot seem to figure out or find online is how to go the other direction - a method to pass objects or tables back to the .NET Webservice from Flex, without stooping to passing XML as a string, or making huge web service methods that have one parameter for each property/column of the object being stored. Surely others, smarter than I, have tackled this issue.
I am using ASP.NET 2.0 Typed DataSets, and it would be really nice if I could just pass one object or array of objects from Flex to the web service, populate my Typed DataTable, and do an Update() through the corresponding typed TableAdapter. My dream would be a [WebMethod] something like one of these:
How can I consume a webservice that hasn't explicitely created a crossdomain.xml? I understand it's for security and to prevent cross-site scripting, but it does seem like a major limitation to the Flex framework. For example, if I want to consume a webservice, which is suppose to be language agnostic, then I can't with Flex. The webservice/server has to be specifically prepared for Flex/Flash. If it's not, then it cannot be consumed.
I am using Flex and Actionscript 3, along with Webservices, rpc and a callResponder. I want to be able to, for example, say:
loadData1(); // Loads webservice data 1 loadData2(); // Loads webservice data 2 loadData3(); // Loads webservice data 3
However, Actionscript 3 works with async events, so for every call you need to wait for the ResultEvent to trigger when it is done. So, I might want to do the next request every time an event is done. However, I am afraid that threading issues might arise, and some events might not happen at all. I don't think I'm doing a good job of explaining, so I will try to show some code:
private var service:Service1; var cp:CallResponder = new CallResponder(); public function Webservice()[code]....
I could ofcourse save the actions in an arraylist, but whose to say that the addToArrayList and the check if other calls are available do not mess eachother up, or just miss each other, thereby halting execution? Is there something like a volatile Arraylist?
I tried to write a function that will strip the carriage return off of strings in a text file... it works fins inside the function, but the changed string is not passed back out... trace commands show that the word is being stripped of the extra characters inside the function, but after the function is called the changed string is not passed back out because the length is back to the original size again
How can i call a CGI script in flex 3? Also how can i retrieve the result of exection of that cgi script?
For example, lets say my CGI script(hello.cgi) just display "hello world". How can i call this script from flex 3 and then retrieve the result, i.e. hello world , so that it can be displayed on my flex application.
I have more than one Event Listener that calls a specific function, and I want to add if statements to check what event is being passed. How can I do that?I tried a simple comparison like:
if(evt == MouseEvent.MOUSE_OVER)
But it will give an error because I comparing a MouseEvent object and a String.
I'm trying to see if a specific date has passed but it's not working. Here's my PHP Code: var currDate:Date = new Date(); checkIfDateHasPassed = function(y, m, d){ var myDate:Date = new Date(y, m, d); if(myDate > currDate){ trace("still to come"); } else { trace("has passed"); }}// since month starts in Zero, July will be 6 instead 7 // I'm trying to use yesterday, but its not working...checkIfDateHasPassed(2011, 6, 10);
My flex 3.5 application has an audio player whose content is accessed by calling an AMF service to get the mp3 data. As far as I can tell, flash.media.Sound is initialized with a URLRequest, so it's not clear to me how I can provide it with data using my RemoteObject.
I want to do one of the following things:
Provide data to the Sound object's load method from a RemoteObject service call. Create a URLRequest object that will perform the requisite AMF wrapping so that my service implementation will look exactly like any other service call if at all possible. Any alternative that allows me to invoke a PHP4 AMF service and play the audio it returns in a Flash audio player.
I've got a movie that i'm calling a webservice from. When I run the movie in flash it downloads the service stub and makes the SOAPCall and loads the data as you would expect. But when i upload it to a site it loads the service stub makes the SOAPCall but "Received SOAP response from network" is not called.
About the files: I load the movie in an html file using UFO. There are some external interface calls before the webservice is called but these definatley return what is required for the webservice to run because the stub does not get downloaded if they don't return anything.[code]...
See [URL] Now there is a button called Answera, which when clicked should have a symbol (movie clip) called Check appear at the cordinated specified. Check exists in the libary (but does not have an instance name) and no where else on the stage. when I run this code I get: 1180: Call to a possibly undefined method Check. -> var rightCheck = new Check(); How is it undefinded if it exists in the libary?
I am just trying to understand what the values sent back from computeSpectrum(bytes,true,0) mean. I have values ranging from 0 to 1 for each float i read from the byte array but does each value represent a range of Hz
I'm trying to make a game that is turn-based and allows players to first be selected, then click on a grid square to move there. However, I can't get a way for a variable storing whether the player is selected to be passed back to the actual grid class. I want the grid class to have an event listener that when the grid is clicked on, it will move the player there only if the player is selected. But whenever I try to declare a global variable either inside the grid class or even a document class or even access properties of the character class I'm trying to move I get errors.
is there a simple way to just pull back a true or false value from an associated javascript file to a flash file? here is what i have:
Code: var bincheck:Boolean = fscommand("eval", "parent.check_bins(\'"+img+"\')"); if (!bincheck){return false;} return true;
check_bins(img) is a function in my javascript file that simply iterates through an array, returning false if "img" is found. im simply trying to get the true or false value back into flash, but its not proving that simple. i added a couple alerts so that i could see what the "bincheck" value was, and i keep getting an 'undefined' value for "bincheck" in flash.
I have an array that I want to check with a "setInterval"-triggered function.Is there a way to do something like an "IF"-check on all entries / fields of an array? The array contains the feedback from another function, so each field can only be "true" or "false".
What I want is something like this: IF (all values from array X == true) { // [stuff] }
Only way I can think of is to set a dummy variable to "true", do a for-loop through the array and check for "false" and if any of the entries is "false", the dummy will be set to "false", too- otherwise it will remain "true"...
I am using flex/actionscript. i have created a webservice with following path [url]... When i run the above url its works fine. but when i use it using httpservice and send method it is giving me error. event[code]...
I am creating a flex dashboard using flash builder. I initially created a flex web based program without any server. This dashboard gets data from SAP query_view_data. And works fine. Now i wanted to host this on IIS. So i created released built. However after deploying on IIS. I receive error : "Security error accessing url.Unable to load WSDL. If currently online, please verify the URI and/or format of the WSDL ". Is this because of some crossdomain.xml. I added this to my webroot, However no luck.
I have an application in Flex how create and XML in UTF-8. When I open it everything is ok.I send it to a server using a webservice (the xml is send like a string), the server receive the xml but all the accent, degree symbol and some other stuff are gone.
I create an XML and save it in a file
var xml:XML = myObject.xml; file = new File(myObject.path); var fileStream:FileStream = new FileStream();
Is there a way to have php call back? Say, if i have an error on the php end, it'll echo "&error=disconnected" or something. I want to be able to call back information However its not working in my favor
We have Flex applications that connect to our ASP.NET 3.5 Web Applications and usually download lot of data. Now considering XML as transport, for every item, it transmits meta data twice for example.. instead of transferring int value as <Customer CustomerID=23/> it transmits <Customer><CustomerID>23</CustomerID></Customer> .. now here is where bandwidth conservation becomes an issue.
FLEX Can not read GZip and DEFLATE compressed HTTP Response ( So cant use any of them )I heard of some WSCompression but it requires WSE 3.0 now I am skeptical to introduce too many dependency in my hosting environment which requires too much management and overheads. Is WSE 3.0 only dll library which requires no installation on production server? Does it require rewriting all WebService attribute? Or is it simple one time configuration and more or less, anyone knows does it work with Flex ? Flex dynamically generates web services, and we use lot of its auto generated code, now if we want to support compression then do we need to rewrite lot of code?
Simplest solution I can think of is, reduce unnecessary XML tags and reduce them down to attributes to save bandwidth. Is there an easy way to achieve it, our classes has more then 50-70 properties, I understand it will be nightmare to add attributes to each property but we dont know how to do it in case of SOAP.
I have My Sharepoint Web Service URL, but when i try to access it i get HTTP Request Error. My Share point Webservice has credentials in it. I have also set that in Flex.
webService.setRemoteCredentials("CITMOSSAdministrator","Pa$$w0rd"); When i trace the url, my console does read the XML, but i am unable to call the method. It throws me HTTP Request Error.
