JTabbedPane problem

[Garandi Garandi]

I want to add 3 tabs into a JTabbedPane, but when I try to add the 3rd one, I get the following exception, if I add 2 tabs I DON'T get any exception.
The code is:

  
tabbedPane.addTab("Main App", null, contentPane, "Main Application");
tabbedPane.addTab("Start Date", null, startDateCal, "Please select the start date for the report");
endDateCal = MyCalendar.getInstance();
tabbedPane.addTab("End Date", null, endDateCal, "Please select the start date for the report");

The exception is

java.lang.ArrayIndexOutOfBoundsException: 2 > 1
at java.util.Vector.insertElementAt(Vector.java:551)
at javax.swing.JTabbedPane.insertTab(JTabbedPane.java:441)
at javax.swing.JTabbedPane.addTab(JTabbedPane.java:480)
at nurse.report.CoverageReport.init(CoverageReport.java:251)
at nurse.report.CoverageReport.main(CoverageReport.java:357)

The exception occures at the last line of code.
Thank you
Garandi

Could you please post more code than that? Specifically where you initialized your entire JTabbedPane, and not just where you are adding tabs. The all the code for that Class would probably be best.

Thank you Gregg.
This is the code for the application.
