Hello again. Doesn´t anybody have a solution to my problem? I don´t know if maybe theres something I need to clarify.
The engine sends "messages" that are java objects that I in the (?????) part translates to somethin on the form that the ApacheEngine wants. What I don´t understand is what I should do with the "context" and "evauator" in my model, can I work around it somehow? best regards //Linda On Tue, Feb 17, 2009 at 1:52 PM, Linda Erlenhov <[email protected]>wrote: > Hello > I have just begun using the Apache SCXML and I have encountered a problem. > > This is what already is: > I have an editor for HMI.
