Dear Wiki user, You have subscribed to a wiki page or wiki category on "Jakarta-commons Wiki" for change notification. The following page has been changed by WolfgangFrech: http://wiki.apache.org/jakarta-commons/SCXML/FrequentlyAskedQuestions The comment on the change is: Deleted previous addition. Sorry, does not work. Still looking for a way. ------------------------------------------------------------------------------ However, this has been implemented in trunk, so with the next release of Commons SCXML the SCXMLExecutor instances will be Serializable. Listeners and other associated user-supplied bits are expected to be Serializable. - - ==== How do I specify the initial substate when extracting a state descending from a <parallel> element into an external file? ==== - - Use the initialstate attribute of the scxml element in the external file, and delete the initial pseudostate element with the transition to the initial substate. - - Example definition before extraction: - {{{ - ... - <parallel> - <state id="a"> - <initial> - <transition target="a.initial"/> - </initial> - <state id="a.initial> - ... - }}} - - Example definition after extraction: - {{{ - ... - <parallel> - <state id="a" src="a.scxml"> - }}} - - Extracted definition: - {{{ - ... - <scxml - ... - initialstate="a.initial"> - <state id="a"> - <state id="a.initial"> - ...
<snip/> where a.scxml is: <scxml ... initialstate="a.initial"> <state id="a.initial"> ... and any <onentry> and <onexit> from the original state with id "a" will have to be assimilated into the initial and final state(s) in a.scxml. -Rahul
- }}} - - Ellipsis ... marks omitted elements or attributes. - - Reason for this entry: I found it a bit confusing that there are two ways to express "initiality" of a (sub-)state, one by declaring initialstate, one by adding an operation, that is an unconditional initial transition. This is even more confusing during the "extract" refactoring, because I had to switch from the operational to the declarative method. -
