correct this small bug lurking in

*/
public void setLocal(final String name, final Object value) {
getVars().put(name, value);
try {
if (log.isDebugEnabled()) {
log.debug(name + " = " + String.valueOf(value));
}
}
catch(NullPointerException npe) {
System.out.println("SimpleContext::setLocal log.isDebugEnabled() where log="+log+"

}
}
*Obrigado Guilherme*

AFAICT the above NPE only can occur when configuring an invalid/wrong logging
class (like in the pom.xml for the maven-surefire-plugin) and/or through
explicitly set the the Log instance to null in SimpleContext.java.
When using a clean checkout/clone of the current SCXML git repository (master)
this definitely is not the case, and mvn package works just fine.
So possibly you have local modifications, either to the pom.xml logging
configuration or otherwise causing this exception?

Ok Folks,
I will evaluate SCXML.
BTW, I found these paper and it sounds interesting:
http://cdn.intechopen.com/pdfs-wm/46457.pdf
It looks like it exports Stateflow to SCXML
MG>will Stateflow support Harel FSM?
MG>Please confirmMG>Obrigado!

Guilherme,
I have not seen much activity. We are all volunteers here, if you want
the
project to move forward, feel free to talk on this list, create Jiras,
and
provide patches.

Hi Folks
I am new to FSM and new to SCXML. On the other hand, I am expert in
Simulink, expert in Java and expert in model based systems engineering.
I am currently evaluating SCXML and I would like a*honest, non biased
opinion *on the status of SCXML project.
What I would like to assert if this project has a future, the number of
developers, if the SCXML specification will ever reach a stable
status....and so on
So far, I have noticed few integrations with proprietary softwares....
Simulink Stateflow does not export to SCXML, neither does IBM Rhapsody.
How difficult would it be to create custom tool for these
integrations? And
most important, is it REALLY possible to implement in Java all the
functionalities of Simulink Stateflow, without any drawback, with a
friendly user experience and a steep learning curve?
ps: I am not from telecom industry
