alice-teacher Alice 3 NetBeans Do-Together code issue

[Daniel Abeshouse]

Hello,

Good to see the plugin is being used.

When the palette entry is dragged in it not only adds the code, but also
makes sure there is a static import of the code it calls.
import static org.lgna.common.ThreadUtilities.doTogether;

Your code should work if you add the import by hand, or drag in a
doTogether block to trigger the addition.

Hope this helps.
