Hi,
Thanks, but it doesn't work completely. With the sample example program, it is
possible to
get "page expired" error by pressing the submit button multiple times (works ok
for some presses).
Usual error message is
INFO Unable to get version -1 of page [Page class = syncrontech.examples.blastfurnace.SimpleTestPage, id = 13]
I'm not sure this is related to timing: I changed the ajax timer to run every
10 seconds, so it is less
likely that I would press button at same time when ajax has work in progress.
But I still get these problems.
Ari S.

versioning+forms+timered ajax events do not mix nicely right now. there
are some nasty timing issues.
consider this
event | requested page version | page version after event
initial loading of the page | n/a | 0
ajax timer runs | 0 | 0
ajax timer runs | 0 | 0
xml http request has cued the next ajax call (call A) this call is for
version zero
you press the submit button ( call B ) this call is also for version zero
submit button (call B) | 0 | 1 <!== new version generated due to form
submit
ajax request (call A) | 0 | 0 <== since ajax has requested version zero
the page has been rolled back to version zero
submit button | 1 <== error , since the previous ajax request rolled back
the version to zero form submit fails because it wants version 1
a possible solution i see is to have a way to encode a request (mostly
ajax) for whatever the latest version is. i will look into it soon.
