I’ve been using an internal beta of Fireworks CS3 for several weeks now to wireframe Flex projects, and let me just say… Fireworks CS3 rocks. Particularly with the new Flex components library that comes with Fireworks CS3, and the pages feature that allows me to specify which layers are shared across which pages, the time it takes me to develop wireframes has literally been cut in half, leaving me more time to actually focus on designing the best user-experience.
I wrote up an article with one possible workflow using the Fireworks to design, style and skin a Flex application. You can read the article here at the Fireworks Developer Network.
What’s more, with Fireworks CS3 including a AS3 engine, I’ve packaged the Flex Style Explorer as a Fireworks Extension that will run directly in Fireworks. You can download and install the MXP here.
Fireworks CS3 is required.

Hi Peter,
That sounds very interesting. I always love Fireworks to do quick job, since I’m not a designer I can’t invest my time in design, but fireworks always work very great for me, so I’m interested in this FW/Flex marriage.
It would be great if you post some captivate demo or video to show what you are talking about and people could have a clear idea of the upcomings advances in some seconds.
Just and idea.
Thanks for pointing into this!
Hey Peter–
Fireworks rules. I’ve worked on a project or two in the past while using your wireframes. I must say it opened my eyes wide with how powerful Fireworks is.

Hey Tom,
Good you hear from you. Hope you’re doing well. I’m a convert to Fireworks also… Photoshop still for editting/enhancing photos, but Fireworks for User Interface Design.
Thank for your post. I begin to use this extension and its help me a lot.
Thanks for the insight…Sheesh i was using PS CS3 and completely forgot about Fireworks, until i found this post!!
