Re: Cuppadev » Running into Flex Limitations

Hi,

FWIW, the limitations you're running into with Flex and OpenLaszlo are due to limitations in the Flash player's transport mechanism. If you try the DHTML runtime in Laszlo, you'll find these limitations removed, as they're not imposed by browser javascript as a runtime. This is the beauty of a multi-runtime system - you aren't hindered by the limitations of one specific runtime!

Hi James,

I couldn't resist :). There's now support for rotation in trunk. If you pull down a copy after tonight's build you should be able to use setRotation() in webkit nightlies!

P.S. Here's the changeset in case you're curious how it works:
