I have to report a huge regression because of Tapestry Compression.
I just tried running with the latest tapestry and it worked just fine most of the time ( going against browsers ), but we interact with the Facebook proxy, and it looks like they got totally confused with the tapestry compression support, thus they would only serve up an error page. Luckily, with Tapestry's new configuration override feature (thank you howard), I was able to turn it off easily, and have my app working again.
public void contributeHttpServletRequestHandler( OrderedConfiguration<HttpServletRequestFilter> configuration )
configuration.override( "GZIP", null );
So I wanted to report this regression, it might be the case that I'm the only one affected, but we don't for sure, and probably people will never realize why it doesn't work. I don't know if any other issues might arise from tapestry-compression, but I will want to make sure I can turn the feature off as I need to.
