I see this too:
When I press a printable char (e.g. "a") then there is no cursor in 
JTextField (and KeyListener doesn't work).
When I press F2 or double click then there is cursor in JTextField (and 
KeyListener works).

About confusion above, there is at most one cell under edit. So there is 
no problem.

I'm seeing exactly the same problem in my application, and is weird
because I'm sure the key listenr is in there, because I made some
prints and I get this:

sCellEditable Called
getTableCellEditorComponent Called
com.psft.driverconfig.mcms.rtu.McmSRTUConfigScreen
$HoldingRegFormattedTextField$1@10e790c
isCellEditable Called
getTableCellEditorComponent Called
com.psft.driverconfig.mcms.rtu.McmSRTUConfigScreen
$HoldingRegFormattedTextField$1@10e790c

The first three lines is after double click and the next three lines
is after pressing a character. In the getTableCellEditorComponent I'm
printing the value of the registered Key Listeners and in both cases
is the same. What I'm guessing is that the JTable KeyListener is
probably getting the keypresses and sending those to the JTextField
using another function.

OK now I know why this is happening but I still don't know how to
solve it. When a cell is double clicked the JTextField gets the focus.
If a key is pressed in the table the table gets the focus. I learn
this by overriding the requestFocus in the JTextField to print
something everytime is called and I get this:

isCellEditable Called
getTableCellEditorComponent Called
com.psft.driverconfig.mcms.rtu.McmSRTUConfigScreen
$HoldingRegFormattedTextField$1@1968e23
Focus Requested!

isCellEditable Called
getTableCellEditorComponent Called
com.psft.driverconfig.mcms.rtu.McmSRTUConfigScreen
$HoldingRegFormattedTextField$1@1968e23

The first case is by double clicking the cell and the second one is
pressing a key in the cell. Another way of showing this is that if you
double click over the cell, using the arrows moves you between
characters in the JTextField. If you enter with a keypress when you
press a cursor key the focus goes to another cell table, so the table
keeps the focus and feeds the underlying JTextField.

I tried solving it everriding the prepareEdiotr in the JTable and
asigning there the focus to the JTextField, but the focus is changed
after that.

I found a solution that might work for you Chamaleon. Just do
setSurrendersFocusOnKeystroke in your table. That will force your
table to give the focus to the JTextField. This doesn't work well for
me because at least the first typed character is transferred to the
JTextField, and I'm trying to filter characters so only numeric values
can be introduced.

I'll keep the research, but if somebody knows how to solve this
problem I would appreciate it.
