Problem when generate faces response with non-faces request in SEAM:(
Hi, All. I have some problem, when try to use custom HttpServlet in SEAM.
If I does not use custom servlet - all OK, page renders, data exist and all cool (no errors, no warnings). If I use application scope as storage for my custom servlet and controller - all works, but I have errors on render phase :(
If I use conversation context - nothing works, error does not changes, but xhtml can not find controller :( so no data at result :( Could anybody help me? Big thanks for answers.
P.s.
SEAM JIRA bug here - bug repport probably was not very good, but answer was worse.
This is error log:
