1009 error with a simple implementation

[Alphaflex]

Hello yesterday i found your package, this is a great idea, i want to
try it with an FCKEditor inside... but

I try it as implementation you give in the doc and Iframe give me an
error

The iFrame is on a ViewStack (bad issue?)

<flexiframe:IFrame id="googleIFrame" label="Google" source="http://
www.google.com" width="80%" height="80%"/>

This is the error -->
TypeError: Error #1009: Il est impossible d'accéder à la propriété ou
à la méthode d'une référence d'objet nul.

Maybee is an simple issue but can you help me to understand how to
correct this ?

Thank.

Hi, I think this is because flex-iframe is not ready for Flex 4 yet, see this issue:
http://code.google.com/p/flex-iframe/issues/detail?id=42
The component uses a property that is deprecated in Flex Gumbo. It should not be a big work to correct it looking at the comments.

By the way, this is weird, your stacktrace mentions the path where the library was compiled:

at com.google.code.flexiframe::

IFrame/createChildren()[/home/nicoulaj/workspaces/flexiframe/flexiframe/src/com/google/code/flexiframe/IFrame.as:252]

I had never noticed that.

Another thing: I did not try it with FCKEditor or TinyMCE yet, which are quite Javascript-heavy, some surprises are expectable... If you try it, please tell us how it went and give us some feedback !
