What version of JMP are you using?

How many levels do you actually have?
I can not find a specific reference to your specified Warning Message. I suggest you contact JMP Support at:
Ok, so it took me a while to simulate the problem so that i can post it here.
follow below steps
1. run the script code below. it will give a one way chart.
2. on the oneway chart.... Red menu triangle>>Redo>>Relaunch ananlysis>>Ok
Names Default To Here( 1 ); dt = New Table( "Little Class", Add Rows( 10000 ), New Column( "name", numeric, Nominal, formula( "L_"||char(Random integer( 1, 6000 )); ) ), New Column( "height", numeric, Continuous, formula(Random normal( 2, 2.5 ); ) ) ); ya="height"; xa="name"; dataTable( "Little Class")<<Oneway(Y(:eval(ya)), X(:eval(xa)), Automatic Recalc(0), Box Plots(1));
Thanks for digging until you figured out how to recreate the error. Unfortunatly, I am not aware of how to eliminate the warning messsage.
