Focus stays on cell when I select column in JTable

Question

Hi,
I am using a JTable and I have defined a function key cntrl-D to perform a function on a selected column. This works fine if I have not yet edited one of the cells in the column, but if I edit any cell and then click the column header and hit cntrl-D, then the column is deselected, the top cell enters edit mode, and my function is called with only one cell selected (always the top cell) instead of the whole column.
When I debug this, I find that my function is called first, and processKeyEvent in the cell editor is called later. The editor doesn't handle it and calls super().
I think that somehow the cell is keeping the focus even though I try to deselect it when the column is selected in my column header listener. Any suggestions welcome.
Here is the code I use to select the column in the column header listener. I have verified that it is called when I click the header:
public void mouseClicked(MouseEvent e)
table.requestFocusInWindow();
Point thePoint = e.getPoint();
int theColumnIndex = table.columnAtPoint(thePoint);
int theLastRowIndex = table.getRowCount() - 1;
if (theLastRowIndex > 0 && theColumnIndex > 0 && theColumnIndex < table.getColumnCount() )
if ( e.isShiftDown() && table.getSelectedRowCount() == table.getRowCount() )
table.editingStopped(null);
if ( table.isEditing() )
return;
if ( theColumnIndex <= mColumnStart )
table.setColumnSelectionInterval( theColumnIndex, mColumnStart);
else if ( theColumnIndex >= mColumnStart )
table.setColumnSelectionInterval( mColumnStart, theColumnIndex );
else if ( e.isControlDown() && table.getSelectedRowCount() == table.getRowCount() )
table.editingStopped(null);
if ( table.isEditing() )
return;
if (table.isColumnSelected(theColumnIndex))
table.removeColumnSelectionInterval(theColumnIndex, theColumnIndex);
else
table.addColumnSelectionInterval(theColumnIndex, theColumnIndex);
else
table.editingStopped(null);
if ( table.isEditing() )
return;
table.clearSelection();
table.setEditingRow(-1);
table.setEditingColumn(-1);
table.setRowSelectionInterval(0, theLastRowIndex);
table.setColumnSelectionInterval(theColumnIndex, theColumnIndex);
mColumnStart = theColumnIndex;
SampleManager.getInstance().setupMenus();

I found the answer. This is a feature that worked in 1.3.1 but broke in 1.4.1. It turns out that there is a new feature in JTable that jumps into edit mode when a key event is detected, and that causes the column selection to be canceled. To inactivate this feature I put the following line into the constructor of my JTable subclass:
putClientProperty("JTable.autoStartsEdit", Boolean.FALSE);
