Srinivas, don't say other to do WHAT if they are following the basic Netiquette?
These are the following reason why you can't give tongue to community member:
1. You are not authorized as I think you are not the admin of the group.
2. I am not getting paid to deliver the solution.
3. This is a free forum and you are free to post solution or your opinion.
4. I love to debug the code and specify the exact solution if I am aware of.

To be more specfic, please refer to the attach IntegratedEncoder.FXP project 
where I have merged your controller logic into a single MXML file as the basic 
rule to create a flex application is to have only one Applicatin container as 

About the Application container
The first tag in an MXML application is either the <s:Application> tag for the 
Spark application container, or the <mx:Application>
tag for an MX application container. The application container then becomes the 
default container for any content that you add to your application.

In IntegratedEncoder.mxml, the <s:Application> is the root tag, whereas is extending the <mx: Application>.

Please read the complete email before you ask for something. I understand you 
like to help, but please read-up completely, understand problem & then ask for 
things to help more.


Whether you use Command-line or Flex Builder it doesn't matter, you always will 
try to compile 1 application in entire project, unless you have two or more 
applications in the project. Correct me if I am wrong, as my understanding goes 
you have file which has class definition for 
"EncoderController" class which extends I guess from Application/Sprite. I 
guess this is the reason your project's main mxml file has root node as 
<local:EncoderController...../>. Now if you are using Flex Builder, normally 
the main application mxml file which Flex Builder Template creates has root 
node as s:Application. In your case, after that mxml is created all you need to 
do just replace that default auto generated code by your old mxml contents & 
include in the src directory, which should work fine for 

FX:Script tag is used in mxml to just include AS scripts which doesn't have 
class definitions. Normally these AS files would have methods, variables etc 
required or used in MXML file. I hope you know that any MXML file can use 
fx:script tag and write the AS scripts stuff required in that particular MXML. 
Treat this MXML+AS script as class.

The reason why you getting error in first place is, the MXML file which you 
have is extending from spark::Application [hence root tag as s:Application] & 
included AS file has definition of a class which also extends from 

Writing code and compiling with SDK using compile time shouldn't be different 
from using Flex Builder. In-fact it gives more flexibility & user friendliness. 
Please read-up more on using Flex Builder, should help you convert your 
application more easily.

Let me know if you need more help.
