JTable Problem(Urgent)

I want to add two components in a Column in JTable (a combobox and radio button in a single column and different rows of the column) How will I do it is it possible to have this in two different CellEditor and Renderers or something else has to be done. Please give the code.

There are several good examples of table rendering and editing out there. Here are two:
http://www-106.ibm.com/developerworks/java/library/j-jtable/
http://www.javapractices.com/Topic168.cjp
Niether addresses different renderers / editors on a cell by cell basis but I know I have seen an example somewhere. But you should be able to get there from the above examples and using your own JTable implementing:
public TableCellEditor getCellEditor(int row, int column)
and
public TableCellRenderer getCellRenderer(int row, int column)

DATE FIELD PROBLEMS - URGENT

I´m having trouble with FormsCentral.
My form is running about 8 months with no problems.
Yesterday people started to complain that the system doesn´t accept any date.
That means the date field restricts date entries, from date dd/mm/aaaa (brazilian format) to another dd/mm/aaaa, but every date that users input in, is considered by the system as invalid, even it´s a correct and valid date right between the interval specified!
I need Help Urgent!!!
I depend on these forms to finish the payrol service from here.
Thanks
I´ll be waiting.

It look like the system accepts just dates starting from the date of today.
I´m testing.
Please help.
Thanks
Message was edited by: SNOWMAUSS
It looks like the system have some problem just with the date 20/10/2013?!
I´ve fixed the problem change the interval from 20/10/2013 to another date and used 21/10/2013 to another date and it works!
But I think something is wrong with the 20/10/2013 date?!
To reproduce the erros just create a new form with date feature with this exaclty configurations and the bug appears:
I´ll keep waiting

Hi
I´ve concluded that the problem persist if the date interval starts at the
specific date "20/10/2013". Don´t know why?!

There are too many mistakes in your program. It looks like you are new to java.
Your add and delete row buttons are not working because you haven't registered your action listener with these buttons.
I have modifide your code and now it works fine. Just put some validation code for the textboxes becuase it throws exception when user presses add button without entering anything.
Here is the updated code: Do the diff and u will know my changes

JTable: renderer problem-urgent

Thanx "pasteven". That url is too good.
I wrote my own renderer for each cell in JTable that uses JCombobox for rendering purpose. But when i select an item in that combo box, some times renderer is not setting the selected item in that combobox. Sometimes when i change the selection of item in the previous cell,it is getting reflected in all other cells of that particular column.
Here is my code. Please help me.

Please help me.

I ran into the same problem in Java 1.4. The problem is that the JTable is not feeding the initial value to the cell editor. I found the following workaround. You have to override the JTable method prepareEditor() like this:
<CODE>
public Component prepareEditor(TableCellEditor editor, int row, int column) {
Component ret = super.prepareEditor(editor, row, column);
// Translate column to the data model coordinates by using the
// identifier. We'll check only for the JComboBox columns (in
// this example columns 8 and 9).
int col = 0;
String id = (String)getColumnModel().getColumn(column).getIdentifier();
if ( id.equals( tableModel.getColumnName(8) ) )
col = 8;
else if ( id.equals( tableModel.getColumnName(9) ) )
col = 9;
if (col == 8 || col == 9) {
String item = (String)tableModel.getValueAt(row, col);
((JComboBox)((DefaultCellEditor)editor).getComponent()).setSelectedItem( item );
return ret;
</CODE>
You have to translate from table coordinates to table model coordinates in case the user reorders column - if you don't allow this for your table then you won't have to do this.

JTable Display problem (urgent)

Hi all,
Does anyone here know how to make a all columnns in my table visible
This is my code. It simple bunches up the columns but I need them spaced out.
Thanks all :)

If I understood you correctly, I think this is what you need:
// Prohibit table from resizing itself
jTable1.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

JTable Problems - JDK 1.2.2_05a & JDK 1.3.0

Hi,
I have a JTable program that works in JDK 1.2.2_05a but it no longer works when I run the 1.2.2 compiled version in a 1.3.0 environment or compiled and run in a 1.3.0 environment. The problem is that the JTable doesn't accept any keyboard inputs. Is there a known issue about this? If not, has anyone else run into this problem before? Any help is greatly appreciated. Many Thanks In Advance!
Juivette

I too face a similar problem. I had a JTable code which worked perfectly in 1.3.0. But when I recompiled it in 1.2.2_09 and ran it., I get square boxes when I try to set value to a cell.
I think., the square box is the Enter Key I press for setting value. Has any one faced this problem before ?
and suggest how to overcome ??
regards
Sriram

Pricing problem-Urgent

Hi all,
iam getting a problem regarding pricing.
When i make a Sales doc. with reference to an invoice,
everything is being copied from invoice to the sales doc.-customer, material and its no. , sales area, payment terms, incoterms, and material qty. also.
But the pricing of the invoice is not getting copied on to the sales doc.
I have maintained all checks available in the sales doc. type and the item category of the sales doc. type i.e
Pricing: X
and then in OVKK , i have maintained the doc. pric. procedure of the sales doc. type with the pricing procedure of the invoice
and again in the copy control measures, i have maintained
Pricing type: D
But i still not able to copy pricing procedure from the invoice to the Sales doc.
I want the soltn. urgently.
Thanks in advance
Sourav

run VTAF for your sales doc type/bil type
and check item category
set flag for "update doc flow"
and pricing type B
