Re: [Cppcms-users] Issues with resubmitting context in v1.2

[Artyom B. <art...@gm...>]

1st of all sorry for delayed reply - was offline for a while.

Regarding your error - you had probably missed the concept of filter.
Filter works BEFORE the data was uploaded processed.
So you can do some stuff on the fly instead of downloading big content
and discoverting an issue.

You need to check if request().is_ready() and only than you can use
it/forward it.

Also JSON-RPC class does not support filer handling it is also not
really needed.
