Hi,

Is there a simple way to force all the child components of a Flex app to redraw when that app is resized?

For instance, I have a HDividedBox with percentHeight and percentWidth set to 100. On the left hand side of the divided box is a data grid and on the right side is a number of text inputs. The divided box is not added to the view stack until after the user logs on.

If I resize the app before the HDividedBox is added then the box takes up the full size of the app, whatever that may be. However if i resize the app after the box appears then the box retains the same dimensions it does when it was first added.

I would have expected that on the resize of the app then all the children would redraw (the application component itself appears to). Is there something I’m missing???
