Exception with requesting too large subset area #1

Open acrosby opened 13 years ago

acrosby commented 13 years ago

An exception occurs when requesting a large area of subset.

This occurs when subsetting "dods://testbedapps.sura.org/thredds/dodsC/ugrid/TestCases/ELCIRC/elcirc_delt.ncml" by lat = [30.973509 40.57480] and lon = [-80.580238 -40.786243].

Exception is : "java.lang.ArrayIndexOutOfBoundsException: -1

at java.util.ArrayList.get(Unknown Source)

Most likely due to subtracting the start index from the read value, since the connectivity variable startes at "1" and not "0".
