Display Tree Indexing - how does it work?

There are some cases where DisplayBox Subscripting like

current report()["Summary Statistics"]

gives surprising results. Which information is accessed via the string?

In this example,

JMP doesn't find the first Local Data Filter -- maybe: because it's title is changed to "LDF"?

JMP finds the first summary statistics - although it's title is changed to "statistics".

I first noticed this behavior with a Graph Builder outline box. JMP finds it even when the title is changed.
At the time, I thought JMP was looking for the @helpKey - and that is why it can still find it.

But Summary Statistics (in the example here) doesn't have a helpKey.

So JMP finds something that is not visible to the user.

And it won't find it if it's a local data filter...

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
New Window( "test",
	V Splitter Box(

		Distribution(
			Continuous Distribution(
				Column( :height )
			),
			Local Data Filter(Title( "LDF" )  ),
				Local Data Filter,
	SendToReport(
		Dispatch( {}, "Distributions", OutlineBox, {Set Title( "hello" )} ),
				Dispatch( {"height"}, "Summary Statistics", OutlineBox,
			{Set Title( "statistics" )}
		)
	)
		),

		Distribution(
			Continuous Distribution(
				Column( :height )
			),
			Local Data Filter(  )
		)
	)
);


current report()["Local Data Filter"] << select();
//current report()["Distributions"] << select();
current report()["Summary Statistics"] << select();

There are different ways how the titles of the OutlineBoxes are changes, so let's try:

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
New Window( "test",
	V Splitter Box(

		Distribution(
			Continuous Distribution(
				Column( :height )
			),
			Local Data Filter( ),
				Local Data Filter,
	SendToReport(
		Dispatch( {}, "Distributions", OutlineBox, {Set Title( "hello" )} ),
				Dispatch( {"height"}, "Summary Statistics", OutlineBox,
			{Set Title( "statistics" )}
		),
		Dispatch( {}, "Local Data Filter", OutlineBox, {Set Title( "LDF" )} )
		
	)
		),

		Distribution(
			Continuous Distribution(
				Column( :height )
			),
			Local Data Filter(  )
		)
	)
);


current report()["Local Data Filter"] << select();
current report()["Summary Statistics"] << select();

and indeed:

If the title is changed by sending a dispatch message to the report layer, the report layer will also find the display box via the original title.

Now, let's change the environment:

It's great, JMP doesn't get fooled by the titles, it still finds the display boxes via the english names :)

current report()["Local Data Filter"] << select();
current report()["Summary Statistics"] << select();

Unfortunately, a German JSL developer will see this information in the "Properties" menu:

and it's quite likely that an English speaking colleague will see:

Note to myself:

use English names for Dispaly Box Substripting
use Dispatch(...) to change the title of Outline Boxes, not Local Data Filter(Title( "LDF" ) )
