exception in drag& drop #34

Open muchafel opened 7 years ago

muchafel commented 7 years ago

when running the prototype on the server I get:

java.lang.ClassCastException: cannot assign instance of java.lang.invoke.SerializedLambda to field com.vaadin.ui.components.grid.GridDragSource.dragDataGenerator of type com.vaadin.data.provider.DataGenerator in instance of com.vaadin.ui.components.grid.GridDragSource

it is not severe nor causes the program to crash. however we should investigate what is going wrong here.

I cannot reproduce this exception.
