java - Cannot serialize JavaScript function -

-

i'm trying change page persistence in our xpages application, intending move "keep pages in memory" "keep current page in memory". , of course run-time errors telling me xpages cannot serialize javascript function. function? stack trace shows standard java error stuff, nothing variable or function cannot serialized?

i had similar issues before, , cost me lot of time dig deep in code , solve problem. takes ages... , i've had now.

is there clever way find out function cannot serialized??

update

what openlog logger comes with:

xpages openlog logger not catches uncaught exceptions (it sounds 1 of those), catches component triggered problem. needs error xpage in application (otherwise after error occurs there no render response phase run, xpages openlog logger retrieves details). might track down.

otherwise, check functions you're storing in viewscope etc. might narrow things down. ssjs not designed object orientated programming, think issues arise when storing functions in scope.

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
