Hi Curtis,
You're right, I forgot to mention the fact that I added 1 variable
"myMappings" in SpreadSheet.java which was an array of ScalarMaps. Before,
the additions I made to SpreadSheet.java was (1) the method loadMyDataSet(),
(2) "myMappings" array, and (3) one line that created a "GO" button shown
below:
//public ScalarMap[] myMappings = new ScalarMap[4];
addToolbarButton("GO", "Open small.v5d", "loadMyDataSet", true,
Toolbar)
/**
* Calls loadMyDataSet in Go.java where file is loaded.
*/
public void loadMyDataSet() {
try {
System.out.println("In SpreadSheet, loadMyDataSet(), and in
try clause");
BasicSSCell testCell = new BasicSSCell("testCell");
VisadAPI mine = new VisadAPI(this, testCell);
System.out.println("this: " + this);
System.out.println("BasicSSCell: " + testCell);
//VisadAPI.loadMyDataSet();
mine.loadMyDataSet();
}
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");
}
Now SpreadSheet.java only has 2 additions. I took out the "myMappings" array
because it wasn't need. And I instead just used the line you recommended in
VisadAPI.java:
myBasicSS.setMaps(new ScalarMap[] {Alt_rad, Alt_green, Lat_blue,
Long_red});
and making the appropriate modifications in VisadAPI.java. It still compiles
and runs. But I'm stuck in the same spot as before. When I run java -mx512m
visad.ss.SpreadSheet and a spreadsheet appears. I click on my "GO" button
and the small.v5d does not have my specified mappings. There are no mappings
at all under "Current Maps".
Is there a problem with setMaps?
Attached is VisadAPI.java and the only 2 changes I added to SpreadSheet.java
was that one method and the "GO" button.
Thanks,
Michelle

Hi Michelle,
I couldn't get your code to compile. I received errors such as:
VisadAPI.java:43: cannot resolve symbol
symbol : method myAutoDetect (boolean)
location: class visad.ss.SpreadSheet
mySS.myAutoDetect(false);
^
VisadAPI.java:54: cannot resolve symbol
symbol : variable myMappings
location: class visad.ss.SpreadSheet
myBasicSS.setMaps(mySS.myMappings);
^
This suggests you made additional modifications to the
SpreadSheet that you did not pass along in email. So, I
can't test your changes to determine if setMaps() has a bug.
Why are you playing around with variables like "myMappings"?
You shouldn't need to add any additional fields to the
SpreadSheet, or to BasicSSCell. All you need to do is call
myBasicSS.setMaps with those ScalarMaps you construct in
your VisadAPI.setMappings() method:
myBasicSS.setMaps(new ScalarMap[] {Alt_rad, Alt_green, Lat_blue,
Long_red});
If that doesn't work, and you think the SpreadSheet has a
bug, please send me a test case demonstrating the problem
and I'll look into it.
Thanks,
Curtis
