Usually a "getWidth/setWidth" on a JSF component won't work, because attributes such as "width" are set via EL expressions and therefore you have to setup a rather nasty - and mutable - EL processing environment to get the right data in. Just passing a simple number width value isn't enough.
So instead, you would usually be better off setting the width to a backing bean property like so:
Then instead of pushing the width into the component, the component will pull the width from the backing bean.
