RE: your mail


Attached below is my file that loads in small.v5d and sets up
the mappings. It compiles fine. It also runs without errors. But the default
mappings that I specified do not appear. Would someone be able to tell if I
passed the array myMappings correctly to BasicSSCell's setMaps method?

public void loadMyDataSet() {
        try {
          System.out.println("In SpreadSheet, loadMyDataSet(), and in try
                VisadAPI mine = new VisadAPI(this, new
                System.out.println("this: " + this);
        catch (VisADException exc) {
        System.out.println("VisAD Exception in SS. Could not load file
small.v5d into the SpreadSheet");
        catch (RemoteException exc) {
        System.out.println("Visad Exception in SS. Could not load file
small.v5d into spreadsheet");

System.out.println("exited normally");

Hi Michelle,

Somewhere, you are calling BasicSSCell.addDataSource().
Wherever you are doing that, whether by hacking
in your own extension of the SpreadSheet, or some other solution,
that same method can contain the call to BasicSSCell.setMaps()
immediately afterward. does not use the SpreadSheet; it just uses the
general VisAD functionality.  If you want a SpreadSheet cell to
use certain mappings, call BasicSSCell.setMaps().  If you just
want a normal VisAD display (i.e., not a SpreadSheet cell), then
feel free to use DisplayImpl.addMap() repeatedly to add the maps.
