Null pointer when deploying HelloWorld samples #18

Closed brice-morin closed 9 years ago

brice-morin commented 9 years ago

Even though this does not seem to be blocking (the rest of the deployment is done properly), this does not look very serious :-)

Can you describe the process to get this ?

I am also getting the same error for exercise 1

maxleiko commented 9 years ago

That's because you've gone through all the tutorials. So you've applied some modifications to your HelloWorld TypeDefinition. Resulting in a local model that has a defined greetMessage port, but the model of the HelloWorld TypeDefinition in ex1 does not have any ports.

maxleiko commented 9 years ago

If you clean your local Maven repository and then mvn clean install kev:run on exercise 1, it should not display the error.

brice-morin commented 9 years ago

OK, then the error message makes sense... but the NPE can be discussed....
