Flash CS3 Components and WMode

I recently ran into an issue with the Flash CS3 ComboBox component – it doesn’t render when you set the wmode for the movie to transparent. I was at a loss for a solution until I saw Sex Panzer’s comment on this post.

Following his advice I added a stage.dispatchEvent(new Event(Event.RENDER)) line to my code, which basically kicks the code in the pants and gets it to render the component properly.

I tested a few other components and they all seem to be affected by the wmode bug, so hopefully the solution above works for all of them.

hi just wondering whereabouts you add the stage.dispatchEvent(new Event(Event.RENDER)) to..

Tom-

I haven’t used it with the datagrid component before, so there may be something else going on. I was using the combobox in a custom form component. I had added the component in my class constructor, and added a stage event listener for when the form was added to stage, at which point I made the stage.dispatchEvent() call. You may be seeing a case where the stage is null because the object containing the datagrid has not been added to the stage yet.

So in my form’s constructor I had:

addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);

and then:

private function onAddedToStage(event: Event): void
{
removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
stage.dispatchEvent(new Event(Event.RENDER));
}
