Hello Tim, can you add simple SCXML document that demonstrates the bug. Aleš -----Original Message----- From: Tim Langner [mailto:tim.langner@metralabs.com] Sent: Tuesday, June 05, 2012 1:36 PM To: www-voice@w3.org Subject: Potential Bug in scxml Interpreter-Algorithm Hi, I found a potential bug in the pseudo algorithm of the scxml interpreter. In procedure addStatesToEnter(state,root,statesToEnter,statesForDefaultEntry) there is a if clause for history states: if historyValue[state.id]: for s in historyValue[state.id]: addStatesToEnter(s,statesToEnter,statesForDefaultEntry) for anc in getProperAncestors(s,state): statesToEnter.add(anc) However calling getProperAncestors(s,state) for state where state is a history state will collect all ancestors up to the scxml root element because history states have no childs. This results in leaving and entering all parent states (up to the scxml root) when going back into a history state. I propose to fix this by calling: getProperAncestors(s,state.parent): Best Regards, Tim Langner -- MetraLabs GmbH Neue Technologien und Systeme Dipl.-Inf.
