RichFaces has been recently reformatted to follow conventions brought by JBoss Community.
That all mainly for one simple reason - making the consumption of code by developers simpler, improving readability across all projects.
As the reaction, we have deprecated RichFaces' own checkstyle and IDE settings and took the ones defined by JBoss Community.
This is great stuff Lukas!
As we finalize the git workflow, and begin processing pull requests we will need to ask developers to use these style guidelines so that we can keep the code consistent and easy to read.
