Re: How to survive viewscoped beans/viewmap after session destroy (using client side saving)?
Sorry to bug you all again.. I am still seeking a clarification on above points.. if anyone can please enlighten me. Thanks.

I think the internally used jsf viewstate is not lost, if I use client side state saving(as my pages still work), but then why are those viewscoped beans scoped that were also serialized to page along with the viewstate.

Re: How to survive viewscoped beans/viewmap after session destroy (using client side saving)?
It's just a map to add data - like ViewState. In JSF 2.0 and JSF 2.1, it was used to directly store the ViewScoped beans. Don't know about more internals. 2014-02-21 21:42 GMT+01:00 user 01 user...@gmail.com: Sorry to bug you all again..

2.2.0 and multipart
Hi Just noticed this thread about tomee, myfacs 2.2.0 and multipart request stackoverflow.com/questions/21948228/how-to-get-jsf-file-upload-to-work-on-tomee-1-6 does anyone know if between 2.1.13 and 2.2.0, multipart request has got any new bug? could not find anything in JIRA the guy who posted the stackoverflow question tested with h:commandButton while I've reproduced the problem just switching myfaces jars from vanilla tomee 1.6.0 from 2.1.13 to 2.2.0 and using p:fileUpload [] Leo
