Condition failed for every branch of choose:

During deploying in JBOSS I have the following error:

ERROR [org.orbeon.oxf.webapp.ProcessorService] Exception at  (executing processor: name='{http://www.orbeon.com/oxf/processors}page-flow')
org.orbeon.oxf.common.ValidationException:  (executing processor: name='{http://www.orbeon.com/oxf/processors}page-flow'): Condition failed for every branch of choose: [(/request/request-path = '/xforms-server-submit'), (/request/request-path = '/questions/question_page_1_2'),... (and all of the other pages).

Application works fine for all the pages mentioned in exception, exception appears when I open browser, using defined url. When I go to the next page, every time I have this exception but everything is displayed correctly. I do not have an error in a browser, only in a console.

Does anybody know what might be a problem?

Cheers
