Question: Classic vs. Standard: Arrays of plots in a Maplet

A user recently sent to me a Maplet that includes the display of an array of plots. This maplet works fine when run under the classic interface but not under the standard interface. As I tried to understand this problem I believe I have narrowed it down to a difference in the way the classic and standard interfaces handle an array of plots.

The attached worksheet is a very simplified example that shows the problem. What should happen is that pressing the "Plot single" button should show a single graph, pressing the "Plot array" button plots the empty axes, and pressing the "Plot displayed array" button displays a 2x2 array of plots. The second and third buttons illustrate the need for "plots:-display" in the action definition for this button.

Unfortunately, this works only in the classic interface. In the standard interface the "plot displayed array" button does not display anything. I should add that it appears to work correctly when exported as a .maplet file and run with the Maplet Viewer.

I have uploaded the worksheet:

I could not upload the corresponding .maplet file. To recreate it for yourself, open the worksheet then click File ... Export as ... Maplet file. Then double click on the .maplet file to have it executed within the Maplet Viewer.

Can anyone on this list (particularly Maplesoft employees) explain why this happens - and if there is a way around this problem (other than using the Maplet Viewer)?

Thanks in advance,
