java.lang.IllegalArgumentException: setSelectedIndex: 0 out of bounds at javax.swing.JComboBox.setSelectedIndex(Unknown Source) at net.sf.openrocket.gui.dialogs.motor.thrustcurve.ThrustCurveMotorSelectionPanel.updateData(ThrustCurveMotorSelectionPanel.java:437) The underlying problem was the MotorChooserDialog had been using the GUIUtil.setDisposableDialogOptions call which caused all the underlying models to be cleared when the dialog was closed with the "x" button. This caused the reference to the models in the panel to be disassociated with those in the swing widgets. Since the dialog is reused, this behavior was bad. Changed the dialog so the 'x' button simply hides the dialog and use the GUIUtil.installEscapeCloseOperation to wire in the ESC key.
