Not sure yet. My thoughts are that the compiler will do real parsing and output a canonical form (we do this for the JS side already). Then in FlexJS we'll either have a simple parser, or declare all styles as strings so they can retain their unit information. Then from there we should be able to convert at runtime. It isn't even clear that we'll use the protochain CSS that we used in current Flex. I think the number of objects in the display list that care about styles may be much less than in current Flex so building and re-building a chain populated mostly empty nodes may not pay off against the much faster protochain lookup. -Alex > >Maurice > >-----Message d'origine----- >De : Alex Harui [mailto:aha...@adobe.com] Envoyé : vendredi 20 décembre >2013 15:48 À : dev@flex.apache.org Objet : Re: Managing units in CSS > >It is a lot of work to retrofit the current SDK, because you can't >convert to a number at compile time.
