Why Scripts Group is lost when doing Table Subset?

[#1]

Dear all,

I frequently use table subset, often when having complex tasks with big data,

I try the things I plan with a subset of  1/100 of rows etc. to be much faster for tests.

During that I observed on my system (JMP 16.0, Windows10), that columns groups are kept, but script groups are lost.

This makes no sense to my eyes, or is there any reason for this behaviour?

If not, I would like to issue this for the wish list.

Thanks ...

Names Default To Here( 1 );

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

// group columns
dt << group columns( "numeric", {weight, height} );

// group scripts
dt << group scripts(
	"Graph Builder",
	{"Graph Builder Smoother Line", "Graph Builder Line and Bar Charts", "S_Big_Class_Graph_Builder_Line_and_Bar_Chart_Scp",
	"Graph Builder Line Chart", "Graph Builder Heatmap"}
);

// making subset, why columns group is maintained, and script group is lost?
dt << Subset( Rows( [28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40] ) );

I agree -- it certainly seems like these should be kept!

does anybody know the reason why script groups are lost ?
It is "intentional" - or a bug?

@martindemel ,

can you please find someone @JMP to answer?

Please send it to support@jmp.com for further investigation. and refer to this thread in your e-mail body. Our technical support would be the best touch-point for getting an answer to your "why" question.

@JMP-Andy  just submitted a wish to fix the issue: Inherited Script Groups 

(explanation is for join, but the wish is general: for all table operations)
