Select "Flex Build Path" or "AIR Build Path" on the left.

But if i use this namespace how can i use the <mx: tag??

After adding lib as a SWC folder I tried to use the SuperTabNavigator? (as the base component for a custom component) however I got a could not resolve flexlib:SuperTabNavigator? to a component. The only way I could get rid of this error was to add the SWC itself to the library path. I'm using FlexBuilder? 3 Beta 1 and it all seemed quite happy until I tried to compile (e.g. it gave me code insight etc.).

Is this something that I've done wrong, or something with FB3?

Davide - it is possible to use multiple xmlns attributes in your application, eg:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:flexlib="http://code.google.com/p/flexlib/" ....

Could not resolve <mx:Application> to a component implementation.

This is my problem, how to correct? I am using flex2.0

You could use Flexbuilder3, it is OK. I have the same problem in FlexBuilder2?.

this couldn't be anymore frustrating. its seems so simple yet so many problems. i have flex 2.014.... i am also getting the 'Could not resolve <mx:Application>' error and the 'Unable to load SWC....multiple points' error. if someone can post the installation process with a screenshot per step id be the happiest person in the world till i start having problems using the components.

more descriptive page with screenshots would be fantastic

I'm using Flex Builder 3 (Trail) but i am also getting the 'Could not resolve <mx:Application>' error.

Can someone give us some feedback and a description how to use this swc-lib. Thanks

For the following errors, 1. Unable to load SWC flexlib.swc :multiple points. 2. 1017: the defination of base class Locale was not found. 3. Could not resolve <mx:Application> to a component implementation.

Try running the Flex Builder 2.0.1 updater from: http://www.adobe.com/support/flex/downloads_updaters.html#flex2

In FB3 Beta 3 have same problems with "resolve".

I'm also getting the 3 errors: 'unable to load SWC flexlib.swc: multiple points', '1017: The definition of base class Locale was not found' and 'Could not resolve <mx:Application> to a component implementation'. I've tried installing the Updater, but it gets stuck at the Folder to Update stage (C:\Program Files\Adobe\Flex Builder 2) it says I don't have an existing copy of Flex 2 installed. This folder does contain the Flex SDK 2 folder, but not the Player or the jre. What should I do?

I'm having a similar problem. I've included flexlib.swc in the build library path. I've also set the xmlns. Code hinting works and the flexlib components appear under the 'Components' view in FlexBuilder?. When I compile, I get errors like:

ERROR : Type was not found or was not a compile-time constant: SimpleScheduleEntry.

Unknown Flex SDK: "Flex 2.0.1 Hotfix 1" flexmdi_examples

i got this error, what should i do?

I am working in Flex Builder 3. I do not have the problem of not being able resolve the <mx:Application>, but instead cannot resolve <flexlib:HSlider> to component implementation. Further, when I try to view the example for the HSlider (Slider_Sample?) in the examples folder, none of widget images render (show up as large X's). I retraced the above steps three times to the same end.

I'm trying to build using an ant script in Flex Builder 3. So I have added the following to my mxmlc target:

<compiler.include-libraries dir="lib" append="true">
  <include name="flexlib.swc" />
</compiler.include-libraries>

All I get is: mxmlc? java.lang.OutOfMemoryError?: Java heap space

What am I doing wrong?

why no XSD for this?
