undefined state flashbuilder 4.5

I'm currently having some problems when switching to flex 4.5. In some components, I declared 2 states (opened, closed). At app creation, I set all the components to "closed" state. When launching the ap with flex 开发者_开发百科4.1, there are no problems. But now that I updated the version to 4.5, I got an error saying : "closed" state is undefined at runtime. Does someone heard about some kind of issues ?

Thanks for the help.

You can set "currentState" directly in the component's tag.

Example Component:

<s:Group    xmlns:fx="http://ns.adobe.com/mxml/2009"
            xmlns:s="library://ns.adobe.com/flex/spark"
            xmlns:mx="library://ns.adobe.com/flex/mx"
            currentState="closed">

    <s:states> 
        <s:State name="closed"/>
        <s:State name="open"/>
    </s:states>

</s:Group>

Thank you guys for the help but I solved the problem. It was linked to the graphite theme I applied to my app. I replaced it by the default spark theme. Themes may not be up to date with the new 4.5 version of the builder. Anyway, I took your component state self managment into account :).
