Strange JTable update problems

I am having some strange issues with a JTable.
I have a custom AbstractTableModel that displays various properties of a list of Objects. I am using a java.util.Vector to store this list.
The user is given several JComboBox objects which contain filters for my table, when any of these filters are changed, a class that manages my Database is asked to return a Vector full of objects that match these filters.
I then set my table data Vector equal to this returned list and invoke fireTableStructureChanged() from my table model. This part works fine, the strange thing is, if the user has a table element selected and then they change the filters, the table will not update, it actually goes blank, but oddly enough the scroll bar on the scroll pane stays the same length as the old table.
When I invoke the exact same update method again (which just sets the Vector containing my data to a new value, and fires the event) the table will update this time.
I have tried calling MyJTable.getSelectionModel().clearSelection() in the hope that it will fix my problem, but it does not seem to do anything.
So is my problem some strange event or threading glitch, or an issue with JScrollPane mabye?
Thanks in advance for any help

Try using the DefaultTableModel to see if you have the same problem. If not then you know the problem is with your custom TableModel.
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)",
see http://homepage1.nifty.com/algafield/sscce.html,
that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting.

A Very Strange Post Update Problem

Hi guys, new to the forum here, wondering if I could get some help with a most disturbing problem...
Off the bat, I use a ppc Mac G5 running 10.4.11. I use this for Music production, and general music listening in my studio. For Audio I use pro tools HD 7.3 (as well as logic 8), with a digidesign 192 IO interface, and run most ofmy audio thru that. Now that we have that out the way... I normally dont agree to updates, as I would not like to upset a balance thats been working perfectly for me for some time, but 2 days ago, one of my assistants was using the computer and agreed to the latest update for Itunes, quicktime, and logic (but not the security update). Immedietly after the update finished (during which he said the quicktime update crashed), the system started going haywire, pro tools was shutting down, itunes wouldn't open, the like... Well after uninstalling and reinstalling itunes and quicktime, all order was restored, except for one AWFUL problem.. the sound coming out of any program BESIDES pro tools (itunes, logic, toast) is very strange, as if its coming thru very cheap speakers. I've run itunes through both the digi interface and the standard sound card (it has the same problem), and checked the EQ settings (flat), my sample and bit rates are straight... I have no idea! if anyone could offer some insight, It would be much appreciated! Thanks!!

HI and Welcome to Apple Discussions...
It's possible there's an underlying problem with your hard drive.
Insert the installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
Also, make sure you have sufficient drive space. Control or right click the MacintoshHD icon on your Desktop. Click "Get Info". Under the General tab you will see Capacity and Available. Make sure there is at least 10% available disk space, 15% is better.
If the drive appears to be ok and you have enough available disk space, you could try the 10.4.11 combo update available here. http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx10411comboupdat eppc.html
Make sure and run Disk Utility and repair disk permissions BEFORE and AFTER the installation.
Quit any open applications/programs. Launch Disk Utility. Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac.

Jtable Update problem .. Please help !!!!!!!!

Hi ,
I am trying to get my updated Jtable, stored in a table of database over a previous table ......after updating it via drag n drop ....

Please help !!!!!!!!
Thanks in advance.....

Here is the code Do you expect people to read through 400 lines of code to understand what you are doing?
Why post code with access to a database? We can't access the database.
Search the forum for my "Database Information" (without the space) example class which shows you how to refresh a table with new data.
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.

Strange waveform update problem:Urgent!!

I got a very strange problem with my waveform chart display, it can only display 2 plots on one waveform chart. I need to display 4 plots on one waveform chart at the same time, please give me some good ideas how to do this. The waveform chart reference is used. My program has been attached, please run it to see the problem, only zeros are displayed, if you only connect two data, the display is correct (you need to change subvi). LabVIEW8.5 is required.

Update problem - VBDATA table

Dear All,
We have update problems in our Quality systems, and also in every R/3 system that we create from a Production system copy.
Sometime the UPD and UP2 work processes hung without apparent reason.
In the SM50 I can see one or more of my update processes running for a lot of time (many hours) on the table VBDATA without perform any action.
In the tcode SM12 I donu2019t see any kind of lock, and I donu2019t understand why only sometime this problem happens.
Of course, from the SM13 I can see that during this problem the system is not able to perform any kind of update.
As I told in the beginning of the message, I have the same problem in other two R/3 systems, both created with a system copy from the production system.
The Production and the Developer systems seem not affected by this problem.
Have you got any idea about the reason of the problem?
Even if the Production systems is not directly affected, all the IT department is not able to work on the Quality system (or any other Test system), and the only workaround is to kill the UPD (or UP2) WPs affected.
Thanks in advance,
Federico Biavati
My R/3 System is a 4.7 on SLES9 and Oracle 10.2.0.2

Hello Siva,
This is what I did:
> Check how many entries do you have in VBDATA currently.
More than 1.000 in every SAP systems that Iu2019m creating from Production
> You might want to run the reorganize updates program to clear the old updates
> that are pending/in error
Good point!!
After the reorganization (ST14 u2013 Reorganize update requests) the table VBDATA is empty.
Iu2019ll check and Iu2019ll let you know if the problem is definitively solved.
Thanks for you help,
Federico

Chart x scale update problem

LabVIEW 8.5.1
Sweep Chart Problem
The x scale values do not update until after the 2nd sweep. The red line cursor gets to the end of the sweep and starts the next, but the scale numbers do not update until the next sweep starts.
It appears to be a problem with the chart, since it happens with any vi with a sweep chart. I've used versions 6 through 7 for years and never seen this. I've only recently moved to a new job with a new machine and version 8.5.1., so I'm not sure what to try.
I've included a simple example.
Thanks much,
JSC321

You have a typical race condition!
There is no data dependency between the property node and the while loop, so in your case the loop starts executing first and the property node starts slightly later, immediately erasing the first point. Execution order is not defined.
All you need to do is add a data dependency, e.g. as with the error cluster in the image. This forces the property node to complete before the loop is allowed to start.
(Execution order is enforced even if the wire value is not even used inside the loop )
Try it!

Strange JTable behaviour - everything is highlighted

im experiencing some strange JTable behaviour, and im not so sure why. When i run my program, the JTable appears, but all the cells are highlighted in advance. Also, i can now only select one cell at a time. I have set myTable.setSelectionModeListSelectionModel.SINGLE_INTERVAL_SELECTION); myTable.setCellSelectionEnabled(true);and my renderer code is below. I call the renderer by using the setDefaultRenderer method with(Object.class,myRenderer).
I have also changed isCellEditable to return true. If i dont use Object.class, and try to use my own custom class, the JTable is not all highlighted, but it doesnt seem to use myRenderer, and when i click on the header of Column A, all cells from column B and beyond become highlight, which is not normal behaviour. I thought the colum you selected should be highlighted.
Sorry for the long post, i hope the above makes sense...this is really quite bizzare, and im not so sure why this is happening. Thanks for any advice you can give, regards, Rupz

Hi VV!
thanks for the reply - now the table isnt all highlight when loaded, but as for cell celection..thats a different matter. I did have myTable.setCellSelectionEnabled(true); but no, the cell behaviour is really, eally weird, quite hard to explain, but here goes.
If i try to select cell D1 and D2 - D1 is selected, D2, E2,F2 and so on become selected. If i try to add D3 to the mix, the entire row 3 is selected, and as soon as i let go of the mouse button, the entire table except row 1 gets selected. really really weird. Below is my tableModel and what i do to the table. Thanks for your help,
regards

myTable.setModel(new myTableModel(this,40,40));
 // Create a row-header to display row numbers.
 // This row-header is made of labels whose Borders,
 // Foregrounds, Backgrounds, and Fonts must be
 // the one used for the table column headers.
 // Also ensure that the row-header labels and the table
 // rows have the same height.

 numCols = myTable.getRowCount();
 TableColumn aColumn = myTable.getColumnModel().getColumn(0);

 Border border = (Border)UIManager.getDefaults().get("TableHeader.cellBorder");

 // Adding the row header labels

And the table model

 private MySpread mySpreadsheet;
 public myTableModel (MySpread aSpreadsheet){
 super();
 mySpreadsheet = aSpreadsheet;
 public myTableModel (MySpread aSpreadsheet, int rows,int cols){
 super(rows,cols);
// for(int x = 0; x < rows; x++) {
// myCell temp = new myCell(new Integer(x+1));
// super.setValueAt(temp, x, 0);
 for(int x =0 ; x < rows; x++)
 for (int y = 0; y < cols; y++)
 // we initialize it here
 super.setValueAt(new myCell(rows,cols,("")),x,y);
 mySpreadsheet = aSpreadsheet;
 public boolean isCellEditable(int row, int column) {return true;}

10.5.7 update problems

After installing the 10.5.7 update, Mail, iTunes and iPhoto will not run anymore. Anyone else having this problem?

Before I came to these apple discussions re: update problems with 10.5.7, I tried to update this version yesterday and at the end of the download this message came up, the update "Mac OS X update" can't be saved. The digital signature for this package is incorrect. The package may have been tampered with or corrupted since being signed to Apple.
I got the same message. The downloaded file that generated the message was only about 560 KB, indicating it was an incomplete download. I moved it to the trash & tried again. The second download attempt succeeded. I had a minor if nerve-wracking issue with the update (the blue looping screen reported in another topic in this forum) but after a forced shutdown & restart the update was completed successfully.
I have since updated my two other Macs so all those listed in my profile are now running 10.5.7. All do so without any problems & in fact work better & more stably than ever before.
I doubt that I'm unusual in this respect. Some users will have problems but I believe most won't, & for those that do most problems will turn out to be caused by something other than the update itself. So it has been for every previous Leopard update; I see no reason to think this one will be any different.

Cache update problem in Integration Directory

Hi all,
We have a cache update problem in our PI development server.
If we try to edit, save and activate any of the ID objects, under Cache notifications>Central Adapter Engine> all these objects are displayed as gray items.
We have tried:
1. Clearing the SLD Data Cache.
2. Did SXI_CACHE complete refresh.
3. Did CPA cache refresh.
4. Did a complete cache refresh of the server.
5. Restarted the server.
But still the problem has not bee resolved. Could you pls provide your inputs and resolution points.
Thank you very much.
regards,
Jack Nuson

HI Jack ,
first try to manually update the cache from ID select on your cache notifiaction and click on delta cache refresh button and refresh button .IF it does not yied any result then
Perform a full cache refresh using the URL
http://<host>:<port>/CPACache/refresh?mode=full . If the cache refresh happens properly then your problem will get resolved other wise you have to see the cache log to view why it failed there it will show you the exact reason . You might need to restart your java server also if the problem persist .

Saurabh

Twitter Update Problem

Seems I have a Twitter Update problem. 1. I have no pirated software on my computer either from the App Store or anywhere else. 2. I did buy a set off templates for iWork through the App Store with my Bosses Apple ID (it's for work). Is that really the problem. That's ridiculous. The apple ID is mine, as is much of the software, but it's a computer use for work. If this is true it makes the App Store a lot less useful.

my apologies I was so annoyed. I didn't bother to state my issue. The issue is: Twitter is constantly asking to be updated. Even after it's updated. Even if it's deleted. I looked at the forums for a solution and found that people were having this problem who installed pirated app store apps.
I am logged into the app store on my account. All but one of the apps on my machine that come from the app store are on my account. However there is one piece of software on my account that I purchased, by logging out and logging in with her ID, purchasing it, installing and logging out, and again logging in as myself. I don't have an issue with that app. However Twitter, which was installed under my username, constantly says it needs to be updated. Hope that makes it clearer.
