No new StudentPanels appear in InstructorGUI

[KBKrause]

This might be because the proxy is receiving messages from the same IP and considers it the same machine, when it should be creating a new panel for each student.

However, the update messages do not contain information about the sender, so this should be tested on two actual different machines.

    private StudentPanelInterface getStudentPanelAtIndex(int index)
    {
        StudentPanelInterface retval = null;

        retval = (StudentPanel)studentTabs.getComponentAt(index);

        return retval;
    }

    private int getIndexOfPanelWithIdentifier(String ident)
    {
        System.out.println("Ident searching for is " + ident);
        int retval = 0;

        for (int i = 0; i < studentTabs.getTabCount(); i++)
        {
            System.out.println("IP of tab at " + i + " : " + ((StudentPanel)studentTabs.getComponentAt(i)).getIP());
            // TODO
            // Eventually, tabs should have names of students.
            // Then the if statement below should become
            if (((StudentPanel)studentTabs.getComponentAt(i)).getIP().equals(ident))
            //if (studentTabs.getTitleAt(i).equals(ident));
            {
                System.out.println("Found a match");
                retval = i;
            }
        }

        System.out.println("Index is " + retval);

        return retval;
    }

Index of student panels changes each time a new student is added. So instead of using an extra method to get the index of the corresponding panel, use a new function that will get a panel based on an identifier and return the reference to that panel, rather than its index. Pseudocode:

private StudentPanelInterface getStudentPanelWithIdentifier(String identifier) {

StudentPanelInterface retval = null;

for (StudentPanelInterface spi : studentTabs) {
if (spi.getIP().equals(identifier) {
retval = spi; }
}

return retval;
}

if (tokens[0].equals("h"))
        {
            if (ipListing.contains(clientIP) == false)
            {
                System.out.println(clientIP + " has connected for the first time");
                ipListing.add(clientIP);
                updateGUI("h:" + clientIP + ":" + tokens[2]);
            }
            else
            {
                System.out.println("Client " + clientIP + " has attempted to initialize more than once");
            }
        }
        // "Update case"
        else if (tokens[0].equals("u"))
        {
            String updateRequest = Inet.decodeUpdate(tokens[1]);
            updateGUI("u:" + clientIP + ":" + updateRequest);

            //System.out.println(clientIP + " says: " + updateRequest);
        }

IPs reported by "h" and "u" tokens were different, should work now on different machines.
