JSF Flex goal is to provide users capability in creating standard Flex components as JSF components. So users would create the components as normal JSF components and the project will create the necessary SWC, SWF files and etcetera and link the values of the components back to the managed beans using JSON+Javascript and Actionscript. {standard Flex components has been open sourced through MPL license}
Currently many of the standard rich flex widgets (buttons, sliders, inputs [richTextEditor, textArea, ...], progressbars, colorpickers, various panels [accordion, tabBar, ...], and etcetera) have been written as intention of support.
Exadel Flamingo provides a set of commands that help a developer to generate initial code. To bootstrap a project, a developer answers a few questions in a wizard. Based on these questions, a standard project is generated. Flamingo is based on Maven, therefore the new application is generated according to Maven conventions, making it easy for people familiar with Maven to navigate through the project.
The generated code provides all the necessary plumbing and connectivity from Flex or JavaFX to Seam or Spring. A developer only needs to focus on business functionality; Flamingo takes care of the rest. All communications between the user interface and Seam or Spring components are taken care of by Exadel Flamingo.
Exadel Flamingo also provides a set of Flex components that make it extremely convenient to support specific features of Seam on the client side.
