how to use JSL to edit a modal dialog window

[#1]

What is the right approach to edit a modal dialog via JSL?

the idea:

- the function add update button adds a button to the data filter

- it works if it is executed AFTER the creation of the window

- in the actual use case, the return value of the window is used as input for the subsequent code.
   Therefore, <<Type( "Modal Dialog" )
-> the window will be closed before add update button() //post gets executed 

- I tried to add the add update button()  via << on open (
 ... without success 

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

dt << Add Properties to Table(
	{New Script("reread", JSL Quote(caption("reread ...")),	As String( 1 ))});
	
add update button = function ({},
wait();
Current Report()["Local Data Filter",LineUpBox(1)] <<
append(
	b = Button Box( "update",
		b << close window();
		dt << run script( "reread" );
		ShowQueryWindow();				
	)
));

ShowQueryWindow = Function({},
	gui = New Window( "test", 
	//<<Type( "Modal Dialog" ),
	<< on open(add update button()), // doesn't work
		dt << data filter( local )
	)
);

ShowQueryWindow();

add update button() //post: works

One approach for this in JMP 18 is to use a window handler.  The window handler is a function wrapper that allows you to access any window created during the execution of the function.  We are looking at making modal and non-modal behaviors more consistent in upcoming major releases, which should make this easier to do directly through the New Window() function in the future.

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

dt << Add Properties to Table(
	{New Script("reread", JSL Quote(caption("reread ...")),	As String( 1 ))});
	
add update button = function ({win},
win["Local Data Filter",LineUpBox(1)] <<
append(
	b = Button Box( "update",
		b << close window();
		dt << run script( "reread" );
		ShowQueryWindow();				
	)
));

showFilter = Function({},
	With Window Handler(
		New Window( "test", 
			<<Type( "Modal Dialog" ),
			dt << data filter( local )
		),
		Function({win},
			add update button(win);
		);
	)
);

showFilter();

Are you trying to add the update button to the modal window? If you are, I don't think modal window is a report window (it is modal or modal dialog) -> build the modal window in different way

Names Default To Here(1);

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

dt << New Script("reread", JSL Quote(caption("reread ...")), As String(1));


add update button = Function({ref},
	ref["Local Data Filter", Lineup Box(1)] << append(
		b = Button Box("update",
			b << close window();
			dt << run script("reread");
		)
	);
);

showFilter = Function({},
	collector = V List Box(
		dt << data filter(local)
	);
	add update button(collector);
	gui = New Window("test", <<Type("Modal Dialog"),
		collector,
		Button Box("Windows",
			Show(Get Window(Type("Reports")));
			Show(Current Report());
		);
	);
);

showFilter();

I would also suggest trying to add {Default Local} (or defined variable names) to your functions to avoid possible issues but it will require some additional scripting.
