This is theoretically true, but in reality, because we have to listen for children being added at startup time, all you need to offer as an option is the watching for remove. > >Here's the catch: going back to the HorizontalLayout, if you remove a >child, the browser will automatically reposition the children to close the >space left by the child removed.

IMO, it isn't "specialty", it is PAYG. We don't want to only offer fully-implemented browser support. It would be too big and slow and take us a long time to write and test. Many apps can be written without removing a child, so that is an option for our customers. Basic should offer those choices, Express can default to the fattest, slowest, feature-rich thing that still makes us look good. > >Right now, the event listeners watching for changes in the children are >multi-platform.

IMO, LayoutBase on the SWF-side could always implement size change listeners since it would be hard to write a layout without out. > >So perhaps that best thing to do now is wait for FlexJS 0.9 and try this >out an another branch to determine what the procedure should be. I think we have until the end of the week to finish features. Next week should be all bug fixing, and the following week will hopefully be the one vote thread so we can get the release on the mirrors and have it propagate before the Summit. I don't have an opinion on whether this work should be done before the release or not. -Alex
