#36656 — how to update JTable display

Now I must be missing something stupid.  I make some changes to my table model, then I update the index array for my RowFilter from the TableModelListener, then I tell the table to repaint and the scrollpane to repaint and it's showing all wrong rows, but if I scroll it up and back it shows correctly.

Right, just wondering if there's a simple stupid obvious thing I'm missing to tell a table to update the display properly.  Creating the sscce won't be so easy.

I'm using a search with a RowFilter to process table cell values from lucene and display only ones that match.  I made a simple ArrayList of what to display, index = view row, value = model row.

public boolean include(final Entry<? extends Object, ? extends Object> entry) {
   final int idx = (int) entry.getIdentifier();
   if (convertRowIndexToModel(idx) >= 0) {
      return true;
   }
   return false;
}

public int convertRowIndexToModel(final int viewRowIndex) {
   return (rowToModelIndex.size() > viewRowIndex) ? rowToModelIndex.get(viewRowIndex) : -1;
}

This part is working perfectly.  Now I click a button which inserts a row in the middle while some rows are filtered out.  This fires a tableChanged event.  My TableModelListener tells it to reindex and update for the search.  Oddly the values update perfectly but the display doesn't.  Say I have 20 rows matching my filter and 10 visible, it's scrollable.  I can scroll up and back and the rows display correctly.  I could send all the code and it's dependencies to test but a simple executable sample to reproduce would take more time than I have right now.

Did you remember to call

<http://docs.oracle.com/javase/8/docs/api/javax/swing/table/AbstractTableModel.html#fireTableDataChanged()>

?

I did, but I just tested firing it a second time... I think this might be working.
