File chooser does not open, exception is thrown

[mirschel]

When the file chooser is called, e.g. for export layout in explorer, the following exception is thrown:

java.lang.IndexOutOfBoundsException?: Invalid index java.lang.IndexOutOfBoundsException?: Invalid index at javax.swing.DefaultRowSorter?.convertRowIndexToModel(DefaultRowSorter?.java:497) at sun.swing.FilePane?$SortableListModel?.getElementAt(FilePane?.java:525) at javax.swing.plaf.basic.BasicListUI.updateLayoutState(BasicListUI.java:1337) at javax.swing.plaf.basic.BasicListUI.maybeUpdateLayoutState(BasicListUI.java:1288) at javax.swing.plaf.basic.BasicListUI.getCellBounds(BasicListUI.java:929) at javax.swing.JList.getCellBounds(JList.java:1600) at javax.swing.JList.ensureIndexIsVisible(JList.java:1116) at sun.swing.FilePane?.ensureIndexIsVisible(FilePane?.java:1514) at sun.swing.FilePane?.ensureFileIsVisible(FilePane?.java:1525) at javax.swing.plaf.metal.MetalFileChooserUI.ensureFileIsVisible(MetalFileChooserUI.java:783) at javax.swing.JFileChooser.ensureFileIsVisible(JFileChooser.java:597) at javax.swing.JFileChooser.setSelectedFile(JFileChooser.java:478) at org.mpg.dcts.promot.viznav.actions.ExportGraphmlAction?.doIt(ExportGraphmlAction?.java:125) at org.mpg.dcts.promot.vizedit.Editor$1$1.run(Editor.java:291)

It seems that some information needed by the file chooser are not present in that moment. Issue should be add to the KnownBugs? list.

Not reproducible. A testcase would be nice.

Fixed with r9491. The fix is to wrap the creation of the GUI in a SwingUtilities?.invokeLater(). All code that affects the GUI should execute on the Event Dispatch Thread. For example

SwingUtilities?.invokeLater(new Runnable() {

public void run() {

GUI code here.

}

});
