Does edting a table cell update the defaulttablemodel??

hi I am a bit confused by the documentation I have read.. I just want to confirm wheither editing a cell in a JTable should update a value in the underlying model(a defaultTableModel in my case) only by declaring the the below..
<code>
Object data[][] = // table contents
DefaultTableModel dtmodel= new DefaultTableModel(data,column_headers);
JTable table = new JTable(dtmodel);
</code>
or do I have to add an editor or a listener..
thank you

The sequence is as follows:
After cell is completed (by focus lost), the value is passed to the setValueAt(Value,Row,Column) method implemented by your Abstract TableModel type class (e.g. DefaultTableModel). DefaultTableModel stores this value for that cell so that next time repaint on table happens same value is returned for that cell by getValueAt(row,column) method in TableModel. This will also call the tableChanged method of any TableModelListener attached to the TableModel.
Hope you are clear about the flow of actions.

Table to update the substitutes for workflows

Hello, as it is the table to update the substitutes for workflows?

Hi,
Yes - HRUS_D2
Try using function module RH_SUBSTITUTES_LIST or RH_SUBSTITUTION_MAINTAIN to do the maintenance of substitutes.
If this is done in the background then there is an RFC function module (don't know this off by heart though)

I spoke too soon. I tried Facetime again last night and had the same problems. Another factory reset did not work. I think it may be time to just call Apple support.

Update it from iTunes on a computer as described at the bottom of this article; devices running an iOS version prior to 5.0 can't be updated straight from the device. It will be updated to the newest iOS version supported by the device’s hardware.

Doing new JTable doesn't "update" the table on the screen

Hello
I am writing a program in java/swing which has several "layers" of panels. In the constructor method of the frame (using JInternalFrame) I create a new instance of JTable, place it inside JScrollPane which is then inside JSplitPane and then place that as the frame content pane.
In this program I run an sql command and the table is the result from that. Every time I execute a query it should update the table with the new results.
What is bothering me now is that when I execute a query I call new JTable() on the variable that held the JTable() object created on startup. When I create a new instance of JTable() and place it in this variable nothing seems to happen. What I need is some kind of "refresh" button. I tried to construct the whole window again but then the program started behaving odd so I gave up that method.
So, does anyone know how to do this?
The code behind this class can be found at http://www.heilabu.net/kari/Session.java (little commented, sorry :/)
You can see the table being constructed in the constructTable() method.
If I am a bit unclear I apologize, don't know all these technical words in english ;)
Thanks in advance!

You really need to use a table model. The table you created is great and once that is in you shouldn't mess with it. Instead, when you create the table be sure to create it sort of like this:
DefaultTableMode dtm = new DefaultTableModel(<various constrcutors use the one suited for you>);
JTable table = new JTable(dtm);
To set different data on the table set it in the table model and then refresh the table, also through the table model. This works perfectly every time.
dtm.setDataVector(---) <- 2 methods, one for vectors and one for arrays...
dtm.fireTableChanged();
the folowing code shows exactly how to use it
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;
public class RandomTable extends JFrame
GridBagLayout gbl = new GridBagLayout();
JPanel buttonPanel = new JPanel(gbl);
JTable table = null;
DefaultTableModel dtm = null;
JScrollPane tableSP = new JScrollPane();
JButton randomButton = new JButton("Randomize");
Object[] headers = { "a", "b", "c", "d", "e" };
public RandomTable()
this.getContentPane().setLayout(gbl);
randomButton.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent evt)
dtm.setDataVector(randomStrings(), headers);
this.dtm = new DefaultTableModel();
this.table = new JTable(dtm);
this.dtm.setDataVector(randomStrings(), headers);
this.tableSP.getViewport().add(table);
this.buttonPanel.add(randomButton, new GridBagConstraints(1, 1, 1, 1, 0.0, 0.0,GridBagConstraints.CENTER, GridBagConstraints.NONE, new Insets(0, 0, 0, 0), 0, 0));
this.getContentPane().add(buttonPanel, new GridBagConstraints(1, 2, 1, 1, 0.0, 0.0,GridBagConstraints.CENTER, GridBagConstraints.NONE, new Insets(3, 6, 6, 6), 0, 0));
this.getContentPane().add(tableSP, new GridBagConstraints(1, 1, 1, 1, 1.0, 1.0,GridBagConstraints.CENTER, GridBagConstraints.BOTH, new Insets(6, 6, 3, 6), 0, 0));
this.setSize(300, 300);
public Object[][] randomStrings()
Random rand = new Random();
int rowCount = Math.abs(rand.nextInt())%50;
int colCount = headers.length;
Object[][] array = new Object[rowCount][colCount];
for(int row = 0; row < rowCount; row++)
for(int col = 0; col < colCount; col++)
array[row][col] = Long.toString(Math.abs(rand.nextLong())%100);
return array;
public static void main(String[] args)
RandomTable rt = new RandomTable();
rt.setVisible(true);

Can I force Straddle for table cells in the EDD ?

This is a question for the techies:
In my structured EDD, I have created hazard statements according to the ANSI Z535.6 standard, using a table format - with the table heading showing the hazard category (notice, caution, warning, danger) and the rows showing the individual messages. In the individual messages I have an icon to the left and the message text next to it. Visually, it is better to separate the two cells with a thin line. But in the header there is no icon to the left and I would like to remove the thin line. Yes, I am a perfectionist, I know
Here is what it looks like now:
As far as I can tell, there is no way to tell Frame to suppress the column separator line in the heading without also removing it in the body rows. And if I do remove the line, there is still a thin white line visible, as the heading cells are filled with an image covering its entire area (but that image does not cross over the invisible line, at least not in the PDF). Another option would be to use straddle on the heading cells, but I need to be able to do everything from the structured EDD and paragraph plus table formats. Is there a way to do this ?
Thanks in advance
Jang

Hi Michael,
Oh, well. I had already figured out that this is not an option. I did remove the line between the rows, as it does not add any thing to the clarity of the message panels in my hazard statement table. But FM cannot handle two adjacent cells with graphic frames without adding a single hairline between them, even if I told the program that the border should be None. Something about the importance of frames for FM, I guess. I have only been able to remove the extra unwanted and uncalled-for hairline by straddling the cells (manually). Of course I will have to adapt the EDD to allow straddled cells in the header, but that is peanuts compared to the stuff I have been doing to make this design work in the first place.
As I will have to create a small script to perform a series of necessary steps before a book can be published, and my hazard statement tables all have the exact same small problem, I will probably include a script that goes through the whole book and applies a straddle to any cells in the heading row of any hazard table. Being a perfectionist, writing that script before handing my stuff over to my customer will make me happier than not doing it and saving some time by delivering a solution that does not make me perfectly happy.
When all the hard work for my current projects is done, I will try to publish an article on how to implement ANSI Z535 compliant hazard statements in structured FM documents. Might be useful for others, too. I will show you my solution at the tcworld fair, if you have some time for that.

Does syncing to iTunes automatically update the iPad 2? Or is there another procedure to updating the iPad 2?

Hi,
I very recently bought an iPad 2 for my wife. She tried to do some online shopping and couldn't get past the checkout screen. Poor girl tried all day and was so frustrated when I came home. I told her to use my PC laptop and she was done in minutes. I went to the local Apple Store and their advice was to disconnect and reconnect the iPad WIFI connection. And to update the iPad. I sync'd to iTunes and couldn't figure out how to search for updates. Does syncing automatically do the updating?
Thanks

No - to update the operating system (iOS) on the iPad connect it your computer's iTunes, and in iTunes select the Device on the left-hand side, and on the summary tab click 'Check for Updates'. The current version is 4.3.3 - you can tell which version your iPad has by looking at the Version field in Settings > General > About on the iPad (the bit in brackets is just the build number of the iOS release); the iPad's current iOS version is also shown on the summary tab mentioned above. If you do not currently have the most up-to-date version then the download is just under 600 meg, and therefore may take a while to download.

How to refer to fact table to update the same fact table

Here is my scenario. Fact table is having measures basic_sal, Tax, net_sal with dimension key to employee dimension.
I neet to update the net_sal = basic_sal - tax in fact table.
I tried to do a map with fact_table as source and also target. but after deploying the map, it's not updating the net_sal to the existing rows. It's inserting the new rows with dimension key and net_sal columns. so now fact table is having the double the existing rows.
Thanks,
Srini.

Ola Srini,
We have some experience that updating a table while using that same table as source often takes a lot of time... Specially when the table contains a lot of data (which is mostly the case with fact tables).
You can use two solutions. Expand the mapping u use to fill the fact table... The calculations looks not that complex to me... But I could be wrong.
Other solution is to create a temp table where you store all sal types. You could load the fact table from this temp table. Disadvantage of this solution is maintenance of the temp table...

When editing externally (Smart Photo Editor) , LR5 does not stack, show or updates the new image in the catalog

I am using the latest version of Smart Photo Editor to edit in external editor from LR5. On LR4 the new image appeared in the catalog, not so with LR5. I have to go to the folder and Sync it so the image appears. Then all my other images are compiled and i will only see that one image which is the "latest import". MAybe something on the settings?

i found LR5 the most bug infested LR version ever.
i "use" it only as test setup.
real work i still do with LR 4.4.

Updating the key field in a table

I am trying to assign new values to the primary key column in a table. As it is necessary to hold a permanent record of the relationship between the new and old values, I am extracting the old values into another table and assigning the new values from a sequence with an insert trigger on this table.
Within the same mapping, I cannot seem to take the new values from this table and update the original table. Ideally, I would like to update key flexfield colum with the new primary key values using the old primary values as the in the where clause' of the update statement (as opposed to delete and reinsert the rows into) the originating table - as I only pull across the key flexfield column into the number allocation table, this is necessary to preserve the other data.
Can anyone let me know how this can be achieved?...I cannot find the concept of new and old in OWB table updates.
I have tried using the (unsuitable) load type of 'DELETE/INSERT' on this table, but this results in the contents of the table being deleted when I run the mapping.

If it's necessary to change the primary key then your database design is likely wrong. I don't understand why it would be necessary to update a PK unless you use PK with a certain meaning which is a design failure.

How do I insert the tab character in a table cell in Pages 5.2?

I'm typing text in a table cell. I need to insert a tab in the text. I've tried all of the modifier keys with the tab. I read somewhere it would be CTRL>TAB, like Word, but that navigates to the Inspector.

You will need to add a Unicode keyboard. System Preferences > Keyboard > Input Sources. Click the + button in the lower left. Scroll all the way to the end and select Others > Unicode Hex Input. Select and Add this. Check the box that says Show input menu in menu bar. Exit System Preferences.
From the Finder menu, select your recent Unicode Hex Input source (it is a black box with white U+ in it). Now, position your cursor in your table cell between the characters where you want to insert a tab character. Press and hold your option key, then type 0009 (zeroes). This is the Unicode sequence for the tab control character. Space will open in your text. Tabs in table cells survive PDF export. The tab mark will not appear with Show invisibles enabled.
Switch back to your normal country input source in that Finder input source menu.

Change the data in fieldcat and update the database table in alv oops

Hi,
my requirement is i have displayed a fieldcat in change mode and when i change the data and click on save it has to be updated the database table..
this has to be done using alv oops...

Hi,
This code will reflect all the changes into the internal table that is being displayed.
* to reflect the data changed into internal table
      DATA : ref_grid TYPE REF TO cl_gui_alv_grid. "new
      IF ref_grid IS INITIAL.
        CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
          IMPORTING
            e_grid = ref_grid.
      ENDIF.
      IF NOT ref_grid IS INITIAL.
        CALL METHOD ref_grid->check_changed_data.
      ENDIF.
Now after this code is executed the internal table is modified as per the changes done in alv output.
Now you can use this internal table to update the database table.
Hope this helps you.
Regards,
Tarun
