flowComposer.updateAllControllers(); results in Error #1009

Hi,

We are trying to integrate the sample application SimpleEditorWithCSS into a Flex 3 application.

We have upgraded to Flex 4. and using the HALO theme.

The application compiles, but when we try to include the SimpleEditorPanel, and we set the textFlow in it,

we get an error in the set textFlow () function, on the line below:

_textFlow.flowComposer.updateAllControllers();

See below the error that we are getting

The integration and initialization of the component is exactly done like the example.

Anybody seen this before and do you know what we are doing wrong here?

I cannot see in the function where the error occurs, so it's hard to understand what is happening.

Cheers,

Anton
