@ken-han Any debugging you have done as to why or provide a PR to help us fix it?

@sbcontinuum Interesting proposal. Interested in trying it and submitting a PR?

@FlipWarthog wanna check this one out...

The Firefox issue is this I think: https://stackoverflow.com/questions/7377301/firefox-keeps-form-data-on-reload

OK I just fixed the Firefox issue part with this commit: https://github.com/primefaces/primefaces/commit/81662d32dbd24b14acf1a096c0c5f7e843a29e1e It puts it in line with what DataTableRenderer was doing with its encodeStateHolder.
