RE: [flexcoders] How to force construction when creationPolicy=all' does not work?
Not sure when you're running that code. Did you try applicationComplete? But this kind of practice doesn't scale. In a model-view design, the views pull their data from the model so you don't end up with code that pushes stuff downward.

Attempting to force instantiation is usually a sign that you need to rethink your data flow. Use events to grab data from a model when the sub component is instantiated of shown.
