Adding a JTable to my Pane Inside a Dialog Throws an NPE when I pack it

I have created a JDialog. When it comes up, I have a JTabbedPane that has several FormPanels on it. The form panels are loaded in as a form file (I used Abeille to create the forms.) I have had no problems until I tried to add a JTable to one of the forms (again, through Abeille.) I add the form like I did the rest of the tabs, but when I run dialog.pack, it throws a NullPointerException. The table inside that form does not appear to be null as I can get values from it. I cannot see what is causing the null.

private JDialog m_dialog;
private FormPanel m_panelForm;
private FormPanel m_tableEditorForm;
private FormPanel m_fieldEditorForm;
private FormPanel m_seedDataEditorForm;

JFrame appFrame = App.getInstance().getFrame();
m_dialog = new JDialog(appFrame, "Dialog Title"), true);
m_dialog.setName("Dialog"));
m_dialog.setLocationRelativeTo(appFrame);

// Load dialog layout
m_panelForm = getFormPanel("DLG_EDIT_PANEL");
m_tableEditorForm = getFormPanel("DLG_TABLE_EDITOR");
m_fieldEditorForm = getFormPanel(开发者_C百科"DLG_FIELD_EDITOR");
m_seedDataEditorForm = getFormPanel("DLG_SEED_DATA_EDITOR");

JTabbedPane pane = m_panelForm.getTabbedPane("editPane");

//Set up the tabs
pane.insertTab("Table", null, m_tableEditorForm, null, 0);
pane.insertTab("Field", null, m_fieldEditorForm, null, 1);
pane.insertTab("Seed", null, m_seedDataEditorForm, null, 2);

m_panelForm.reset();

m_dialog.setContentPane(m_panelForm);
m_dialog.pack();

The third insert, the one called "Seed" is the one that blows it out; if I comment out the line the other tabs show up fine. Similarly, if I remove the JTable from the form in Abeille the tab shows up fine.

Note the columnCount and rowCount defaults to 2. Also note that if I turn off pack, I have a setVisible off of the JDialog that throws the same error.

Any help would be appreciated; I'm okay at Swing but far from good.
