Flex - could not resolve something?

Hi, I'm new to flex and I'm trying to use the following code
to display "Random Products"
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="
http://www.adobe.com/2006/mxml"
>
<srv:•••••••••
id="myService">
<srv:RandomProducts_request_var>
<srv:RandomProducts_request numberOfProducts="1"/>
</srv:RandomProducts_request_var>
</srv:#####>
<mx:Button id="myButton" label="Call operation"
click="myService.RandomProducts_send()" />
</mx:Application>
but when I run the application I get an error message
"Severity and Description Path Resource Location Creation Time Id
Could not resolve <srv:RandomProducts_request_var> to a
component implementation."
Please can somebody help? It's driving me a bit mental.
Thanks,
Andy

You've defined namespace srv, so is the component
RandomProducts_request_var located inside the com.montpellierdns
folder? If its in a sub-folder of the montpellierdns folder, you
need to specify a namespace specifically to that folder.
Also, com must be a direct sub-folder of the one compaining
your app mxml file, and then montpellierdns a sub-folder within
that.

Flex in a week: error Could not resolve s:Application to a component implementation

Hi All, I've seen other posts mentioning this error but seems no fix has come up.
Was just trying out the example project for Flex in a Week and out of the box am stuck on
" Could not resolve <s:Application> to a component implementation "
the namespace and all expected attributes are in the s:Application tag.
Is there a common fix for using these samples?
thanks everyone for your consideration.

Thanks, I am using Flex Builder 3.

While typing, the keyboard starts typing multiple letters. I'm fed up of this. I don't think I am doing something at my own, it's happening at its own. Is it because of some problem in the hardware since OS and system refresh could not resolve this.

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.
If you have done this like I describe above and the problem continues I suggest you contact Apple Support or make an appointment at an Apple Store and have your iPad examined by a technician.

Upgrade from Burrito to 4.5, Could not resolve MobileApplication tag?

Hello:
As the topic states, I just upgraded from Burrito to 4.5 today. I imported my app and I get the following error:
Could not resolve <s:MobileApplication> to a component implementation.    ...    line 6    Flex Problem
Did they take out MobileApplication? If so how can I support the back button on my Xoom device now?
Paul

MobileApplication was renamed to ViewNavigatorApplication.
Here's an example of how you would cancel the back button in the final 4.5 release:
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark" title="HomeView"

Using AIR 15 (10/14/2014): Could not resolve s:ViewNavigator to a component implementation.

Hi
I want to update to the newest version of AIR so I can upload my ipa to App Store. Usually I get AIR from the Apache Flex SDK installer, but it only has the beta version of 15.0.0.183. I have instead downloaded the SDK from
https://forums.adobe.com/thread/1603494
(AIR SDK 15 (Compatible with Flex) for Windows)
but when I compile, I get the following error:
Could not resolve <s:ViewNavigator> to a component implementation.
I have tried the following things:
* Downloaded AIR 15 SDK from Apache Flex and merged the new files into this SDK (same error)
* Downloaded AIR 15.0.0.183 beta from Apache Flex and merged the new files into this SDK (same error)
* Downloaded AIR 15.0.0.183 beta from Apache Flex (no error, but I don't know if Apple will accept this version)
Am I doing something wrong?
Thanks in advance
Mark

I think I got it to work. Apparantly there is a secret link called "Download Windows" below the yellow download button which is for Flex users even though I already chose the Flex version on the previous page.

Error: "Could not resolve [public class] to a component implementation

Here's another clueless newbie question! :-(
I define a public class "DynamicTextArea" at the top of the file, and get the compiler error message "Could not resolve <DynamicTextArea> to a component implementation" at the bottom of the same file.
Clearly, I don't understand something very basic.
(The code between the commenrted asterisks was originally in a separate package file, which I couldn't get either mxmlc or FlexBuilder to find, so rather than fight that issue now, I moved it into the same file.)

     Thanks for any insight you can provide!

Gordon:
    As you've noted, there were multiple misunderstandings.
    Some are due to references in the language which are different from uses in pre-existing languages.
    Take "name spaces". They look like URLs but they're not. One of the first errors I made when starting Flex was to try to browse to http://www.adobe.com/2006/mxml. I figured that it would have some description of the language. But it didn't. In spite of LOOKING like a URL, it doesn't point to anything; it's really just an arbitrary magic incantation, like "Open Sesame".
    But, then when I wanted to use my OWN namespace, I find that it's NOT arbitrary, and does have to point to something, but it's still not a URL. The "AHA" moment was when Michael told me that "*" means "look in this directory for a file with the name later named in an import statement, but not named here". And if the file was in subfolder "X" I'd have to use "X.*", while if it were a URL I'd use slash instead of dot, but never an asterisk.
    When the language syntax is so contrary to the expectations of people coming from a declarative language or web programming background, I think it is important to explicitly address the differences and disabuse them of their preconceptions. I think the same should apply to the ways in which ActionScript differs from ECMAScript.
    Another problem adding to my confusion is the habit of naming variables with the names of keywords but with capitalization changes. Not only does that set readers up for subtle "gotchas", but makes it unclear which names are truly arbitrary, and which are required by the compiler.
It might be a good idea to have a convention of an identifiable format for user variables. Many authors use names like myButton for that purpose.
    It would also be helpful if printed text could simulate the syntax coloring of the better editors, or at least have more in-source comments saying exactly what each line does. (Or both)
    Another aid to understanding would be to provide a reference to the alternative (MXML or AS) way of doing anything, whenever you demonstrate one of the ways.
    I find that the emphasis on using FlexBuilder distracts from a sense of what is really going on behind the scenes. E,g.: If FlexBuilder automatically sets up the folder structure, I don't learn to do it myself. I like to work at the code level, so when something goes wrong I don't have to worry about what level it went wrong at.
    Also, not everyone is willing to drop $600 or $250 BEFORE they've learned whether they even like Flex. Your tutorials are, by definition, addressed to newcomers who may well not yet have committed to the expense of FlexBuilder. So more emphasis on using mxmlc would be nice. It would also be helpful to discuss how to use local servers, like Tomcat, during the development stage.
    Thanks for asking my opinion. I'm afraid that my 40 years of programming experience may make it harder for me to adapt to this new style of programming than it would be for a kid with a tabula rasa. But, it looks like it'll be fun once I get over the hump!

FABridge in AIR: Could not resolve fab:FABridge to a component implementation

Hi all,
I'm trying to use the FABridge in my HTML-based AIR app to communicate between a swf file and my JavaScript code. Browsing through the forums, it appears that ExternalInterface is not advisable in AIR, so I turned to FABridge instead. Can anyone on this forum advise me on whether FABridge is the correct route to take if I want to communicate betweeen flex and javascript.
If FABridge is the recommended protocol, can someone please advise on how to include the FABridge.as file as part of a amxmlc compiler option. I've tried the following:
seanosheas-macbook-pro:bin seanoshea$ ./amxmlc -sp+=${FLEX_3_HOME}/frameworks/javascript/fabridge/src/bridge ${PROJECT_HOME}/GMapsController.mxml
but I keep getting this error:
Error: Could not resolve <fab:FABridge> to a component implementation.
Looking at Mike Chambers' blog post here: http://www.mikechambers.com/blog/2005/12/22/compiling-actionscript-3-and-mxml-on-mac-and-l inux/, it looks like the air-config.xml file could be modified to include the FABridge.as file. I've tried modifying the air-config.xml file to point at the fabridge/src/bridge directory, but no luck.

Hi Paul,
Thanks for the reply. I was drawn to the FABridge because the documentation said it's useful if:
"You want to use a rich Flex component in an Ajax application but do not want to write a lot of Flex code. If you wrap the component in a FABridge-enabled stub application, you can script it entirely from JavaScript, including using JavaScript generated remotely by the server."
The rich Flex component I'm trying to control in my Ajax application is a Google Maps swf. The swf is pretty simple ... it just looks like this:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
    <maps:Map xmlns:maps="com.google.maps.*" id="map" mapevent_mapready="onMapReady(event)" width="100%" height="100%"
        url="http://code.google.com/apis/maps/" key="ABQIAAAAirgZjEoCu9a3euq95spKkBR_S1ecsaBoILwOJWQZL62AsG_vrBT---yI8NYfu5nSGRvZPcpZobSH zA"/>
    <mx:Script>
        <![CDATA[
            import com.google.maps.LatLng;
            import com.google.maps.Map;
            import com.google.maps.MapEvent;
            import com.google.maps.MapType;
            private function onMapReady(event:Event):void {
                this.map.setCenter(new LatLng(40.736072,-73.992062), 14, MapType.NORMAL_MAP_TYPE);
            public function setLocation(lat:Number, long:Number):void {
        ]]>
    </mx:Script>
</mx:Application>
I'm including the .swf file with an embed tag as outlined in the Google Maps for Flash API documentation:
    <div id="map_canvas">
        <object
          classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"

          width="800px"
          height="600px">
              
              
              <param name="movie" value="http://mysite.eye.fi/GMapsController.swf">
              <param name="quality" value="high">
              <param name="flashVars" value="key=ABQIAAAAirgZjEoCu9f3eua95spKkBR_S1ecsaBoILwOJWQZL62AsG_vrBT---yI8NYfu5nSGRvZPc pZobSHzA">
              <embed
                width="800px"
                height="600px"
                quality="high"
                flashVars="key=ABQIAAAAirgZjEoCu9f3euq95spKkBR_S1ecsaBoILwOaWQZL62AsG_vrBT---yI8NYfu5nSGR vZPcpZobSHzA"
                pluginspage="http://www.macromedia.com/go/getflashplayer"
                type="application/x-shockwave-flash">
        </object>
     </div>
I'm not sure I can include it as a library of classes as you describe in your post.
It would be really sweet if I could attach an id attribute to the embed tag and be able to call the functionality within the swf file in JavaScript.
Do you know whether this is possible or not? I'm pretty new to flex (if you guys havent already guessed), so I could be missing something pretty simple.
Any help is greatly appreciated
Cheers

Could not resolve to a component implementation

I'm using Flex Builder 2 Version 2.0.143459 (Geez, couldn't
you just make it 2.0.144?) and I am running Eclipse version 3.2.1
and I have Flex Charting 2 installed also.
Now, I downloaded the example for "dashboard" that has the
various graphs, and when I go and create these files and copy in
the contents into my eclipse project I get:
Could not resolve <AllRegions> to a component
implementation.
Could not resolve <RegionBreakdown> to a component
implementation.
Could not resolve <RegionDetail> to a component
implementation.
It seems to be something with the namespace? But what is the
solution? I've search these boards and people say uninstall Beta 1,
etc, but I am not running a Beta, AND this is a fresh install for
any Flex at all.
Thanks for any help

OK, I solved the problem -- it was a simple item that got
left out of the top <mx:Application tag
I needed to have xmlns="*" in there, and eclipse does not put
that there when you start a project!
Hopefully this helps someone in the future.

Problems with 3.6 could not resolve s:ViewNavigatorApplication

Hi,
I'm trying to use 3.6 and not having any luck...
I have FB 4.7 (64-bit) on Windows.
I have downloaded from here; http://www.adobe.com/devnet/air/air-sdk-download.html
I have completed the steps here; http://helpx.adobe.com/flash-builder/kb/overlay-air-sdk-flash-builder.html
I have merged the sdk as I would have done for 3.5,3.4 etc.
Now, when I set the SDK to the 3.6 one, I get the error;
"Could not resolve <s:ViewNavigatorApplication> to a component implementation."
_MUST_ be something basic I'm doing wrong here!
Help!
G

Now I'm confused.
The text link you mention states that Flex users should take the SDK version without the compiler. BUT....
the http://helpx.adobe.com/flash-builder/kb/overlay-air-sdk-flash-builder.html page says to download the SDK from
http://labs.adobe.com/downloads/asc2.html
but this page now redirects to:
http://helpx.adobe.com/air/kb/archived-air-sdk-version.html
which contains a large list of archived SDK's. So that help page never really says which version of the SDK to use - with or without the compiler. But other forum posts have implied its suppose to be the one with the compiler.
Now since we're overlaying the ...plugins\com.adobe.flash.compiler_4.7.0.349722\AIRSDK folder that would make sense.
So my questions are:
   Do we use the version with or without the compiler to do the overlay?
   Can we get Adobe to update that help page to reflect what we're really suppose to do?
AND
   Does Flash Builder use this overlaid AIR SDK with any selected Flex SDK as long as the project settings has the 'Include Adobe AIR libraries' checkbox selected?
   What if I've configured the Apache 4.9.1 (Doesn't this have AIR SDK 3.4 embedded within it? - yeah I chose that option in the download installer) as my Flex SDK, then will the 'Include Adobe AIR libraries' checkbox still use the AIRSDK 3.6 I just overlaid?
Is it just me, or is this just getting more and more confusing? Can we perhaps get a AIR SDK combo box to go beside the Flex combo box and when we check the 'Include Adobe AIR libraries' then we can select the AIR SDK we want? And get a 'configure AIR SDKs...' link too?

Could not resolve fx:Script (or fx: Declarations to a component implementation

Hi,
I am trying to compile a file into swf using mxmlc in command line. When it is a very simple mxml, compile is successful. But when the file contaion the fx name space, I get a compile error like: could not resolve COMPONENT_NAME to a component implementation.
I have to be able to do this, without the help of Flash Builder because I am working on a project where I will need to generate swf files from mxml files which we generate the code of.
I tried it with SDK version 4.0.0., version 4.1.0 build 16076 and 4.5.0. build 20967. And I also tried it in 3 different computers. Note: Our notebooks has Windows 7 OS - locale:Turkish.
I read that this error is specific to some locales like Turkish here: http://forums.adobe.com/message/892431#892431, . But I couldnt find the solution.
Any suggestions?
The simple code I am trying to compile is(which is generated by Flash Builder 4 and can be compiled there):
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
                  xmlns:s="library://ns.adobe.com/flex/spark"

     <fx:Declarations>
          
     </fx:Declarations>
</s:Application>

Could you please file a bug at http://bugs.adobe.com/jira with sample code that fails to compile on a Turkish system, so that we can track this problem and fix it in a future release?

AIR SDK 3.6 Could not resolve component

I have Flash Builder 4.6 and the AIR SDK version is 3.5, Today i update the AIR SDK version to 3.6, However when i debug the appliction, the Flash Builder popup a error for "Could not resolve <s:ViewNavigatorApplication> to a component implementation." .
I have downloaded AIR SDK3.6 from here: http://www.adobe.com/devnet/air/air-sdk-download.html

Hi Jack,
Please download AIR SDK from a small note below on http://www.adobe.com/devnet/air/air-sdk-download.html
for flex users.
Note : Flex users will need to download the original AIR SDK without the new compiler.
Please let us know if this fixes your issue.

I am simply trying to get an ant task to compile this library to SWC, but I am getting a " Error: Could not resolve <s:SolidColor> to a component implementation" error during compile. The only way to fix it is to add these lines of code (bold).

I can also get this error to go away if I put this line in my build.xml file: "<include-sources dir="${src.dir}" includes="*"/>"
But then I get this error => "[compc] Error: Unsupported file type: C:\dev_projects\features\flex4version\web\OneVoice\src\components.xml"
components.xml is my manifest file.
Anyone know what the issue is? Why would I need the xmlns:spark="mx.graphics.*" namespace when I have xmlns:s="library://ns.adobe.com/flex/spark"?

Curious. Which version of the Flex SDK are you using?
Does this work if you try in a brand new project using Flex 4.1 or Flex Hero?

Could not resolve Script

I am getting an error message "Could not resolve <Script>
to a component implementation." This is the code I am attempting to run, from
the tutorials offered by Adobe.
<Script>
{import mx.controls.Alert;}
</Script>
I've tried this without brackets, with <> symbols, around the import, and everytime I get an error. any suggestions? I'm brand new to flex, but for the most part find it rather simple to do. however, when i get an error it's impossible to figure out how to fix it!

the <fx:Script> worked. Thanks!!
