First of all, update your ThingML plugins as described here
Note that I have also re-built the HEADS IDE (minimal version) so that it includes by default the latest version of ThingML.
I indeed made changes both in the ThingML-to-Java compiler and in the Java framework for the execution of state machines to better integrate it with Kevoree. I suspect you are generating "old" code and using the new framework, but I will re-test in details and keep you updated.
@sdalgard Also, please assign me explicitly for the ThingML-related issues, so that I get an explicit email (instead of continuously watching my github home page). That will make the process more efficient.
Here is the code you should obtain for the Main.java
of the very first sample of Tutorial 1 (which worked for me in CLI-mode and in Netbeans):
package org.thingml.generated;
import org.thingml.java.*;
import org.thingml.java.ext.*;
import java.util.*;
public class Main {
//Things
public static HelloThing HelloThing_HelloCfg_my_instance;
public static void main(String args[]) {
//Things
HelloThing_HelloCfg_my_instance = (HelloThing) new HelloThing("HelloCfg_my_instance: HelloThing").buildBehavior();
//Connectors
//Starting Things
HelloThing_HelloCfg_my_instance.init();
HelloThing_HelloCfg_my_instance.start();
Runtime.getRuntime().addShutdownHook(new Thread() {
public void run() {
System.out.println("Terminating ThingML app...");HelloThing_HelloCfg_my_instance.stop();
System.out.println("ThingML app terminated. RIP!");}
});
}
}
I guess you are missing the following line: HelloThing_HelloCfg_my_instance.init();
, which would explain the null pointer.
Retry after updating your HEADS IDE and close the issue if it works, or post a comment if it still does not work.
I updated the HEADS IDE ... now it works :-)
I have started on training 3. , but are not able to get anything working..... When trying to go back to basics ... it doesnt work either....
When doing "run" from Netbeans I get:
Building HelloCfg 1.0-SNAPSHOT
--- exec-maven-plugin:1.2.1:exec (default-cli) @ HelloCfg --- Terminating ThingML app... Exception in thread "Thread-1" java.lang.NullPointerException at org.thingml.java.Component.stop(Component.java:96)
at org.thingml.generated.Main$1.run(Main.java:25)
BUILD SUCCESS
