Is there a way in Vaadin to hook into a request chain and perform operations around the real request/response cycle with VaadinSession
provided? Currently I use javax.servlet.Filter
, but it seems that VaadinSession.getCurrent()
is set somewhere deeper, and in the filter itself it is unset both before and after chain.doFilter
().
Vaadin request filter with filter chain?

I have found a workaround. First of all, I can't plug into a request handler chain, as there is no such structure. To simulate it, I have split my code into pre-request and post-request code (It's somewhat OK in my case). I'm doing my pre-request stuff in an ordinary
VaadinRequestHandler
and returning false (for a normal request to proceed). Post-request stuff goes to ajavax.serlvet.Filter
mapped inweb.xml
.Second, if anybody else is having the same problem, and the code is also splittable using the same pattern, here is the a pre-request (vaadin-side) listing:
