Is this a known bug because i could not find anything about such a behavior.
what i tried was to open the new created helloworld project in netbeans by adding all jars from the content of the skd and it worked but i would prefer to use the jme3-ide3.
have some one a idea how i can get the source code editor in jme3-skd?
You can try using the installer (tgz) from updates.jmonkeyengine.org instead of the zip file, depending on your OSX version you’ll have to open the installer package (right-click->view package contents) and run the contained jar file manually as there is a bug with the installer on later OSX versions.
