Strange Keyboard behaviour

I have a strange Problem when using Mainstage. Everything is working fine except the F2 key on my keyboard. I can see, that my MacBook gets Midi Information about the Key pressed but I don't hear any sound. I do not have this problem with any of the other Keys. I do have this problem with every virtual Instrument I use. I also have tried out using another Keyboard or using a MIDI cable instead of USB.
I don't understand how this problem can even exist. This problem also only exists in Mainstage. In Logic the same key, with the same keyboard works fine.
If anyone had similar Problems and a Solution please help me.

I think it might be caused because this key is already assigned to control another item on mainstage's layout, like a button o something else.
If you try opening any of the default mainstage's templates, it should work fine.
another possible cause: I have a fatar keyboard where a key always sends velocity zero; probably its velocity sensor is broken. this makes mainstage display a pressed key, but never sounds as it understands is being played extremely soft. if that was to be your case, on the midi data inspector display you'll see note-off events instead of velocity data.

Tecra 8000: Strange keyboard behaviour after reassembling

Hi,
after reassembling the single keys to my keyboard from Tecra 8000 the keys have a strange behaviour. For example if i press the key 2 the display shows '82' or 'q'. if i hold the key longer, the display shows '2222222222222....', the right sign for the key.
Do you knwo, what i can do?
i had to reassemble the key because my little niece took all the keys off.
thanks for your answer,
Butch

Hi
I agree with Daniel. There is some technical problem and only thing you can do is try to clean the contacts. If there is no success you should replace the keyboard. This unit is older one and I am pretty sure that you can find a cheap used keyboard.

Strange Keyboard behaviour with Pressure on Body

Any else experience this problem?
Basically when I am typing and I lean with my palms on the body of the macbook (not overly hard) the keyboard starts acting really strange. Keys I press won't work, and other keys will just randly start being hit. If I lift my hands off the body of the macbook all returns to normal. Seems like a short of some sort. Is this a common problem or just on my macbook?

Has no one an idea?

Strange Keyboard Behaviour: Function Keys F1-F10 not accessable

I noticed couple a days ago that function Keys F1-F10 not accessable, neither with nor without fn.
Nothing special has been made lately on PowerBook, some days ago tested Universal Access.
What could keep F1-F10 disabled?
BTW F11 and F12 are fully functional

I'm noticing a possibly related conflict: I use Universal Access Sticky Keys all the time (they are just handy). But I noticed after a few days working with my new intel MacBook that when I had sticky keys on the keyboard would be mapped weird: The qwerty keys would be correct up to the num lock keys, and they would be numbers. So they are like this:
qwerty456*[]
asdfgh123-'
zxcvbn0,.+
After several days of removing preference panes and startup items with no success, I just started digging around in all the preferences I could think of that would effect the keyboard. I disabled the "use the f1-f12 keys" option and the keyboard behaved normally.
So, if you engage sticky keys AND have "Use the F1-F12 keys . . ." engaged you get this odd behavior.
However, I still have the function of the F-keys.
Any ideas?

Strange keyboard behaviour with sdlmame

Hi,
I just installed sdlmame and qmc2. I can run games and generally my keyboard works at the very beginning of a game, but after a couple of seconds I have very limited control over my game character. For example I steer to the left for may be a second or so, then I can't steer right until I once again steer left. Soon it is getting so mixed up that the character is moving left when I'm steering right. Same problem for up and down.
It doesn't depend on the game, happens with all keyboard controlled games.
I'm using xfce4 and a keyboard with german layout, but I doubt this is the cause, other germans like to play too, and I haven't read any complains from them
Any help is appreciated!
Thanks,
Alex

Strange keyboard issue on a Satellite P300

Hi,
Since a week i have a problem with my keyboard on my P300.
The keyboard doesn't work when the power supply is on. The keyboard is inactive on vista and in the BIOS.
When i cut the power and the PC is on battery the keyboard is OK.
Do you have any infomations about this problem ?
Thanks.
oliv

Hi Oliv
Such issue is not known to me and I think it must be hardware related issue.
What you can do about it? Not much except to try with BIOS update but I dont think it will help.
Satellite P300 is not the newest notebook model. Since when you have noticed such strange keyboard behaviour?
To be honest I think you should contact Toshiba service in your country. Let them check keyboard and keyboard controller using diagnostic tools. They can tell you what the problem is and how to fix it.

Spooky keyboard behaviour

This probably doesn't belong in the programming forum, but I'm interested in finding out if someone has had a similar problem. I have installed my app at a client site. The app is run on 9 machines. 7 of the 9 operate fine, but on two of the machines I have strange keyboard behaviour.
Ocasionally the app will stop erwsponding to the keyboard, but will still respond to the mouse and still paints ok. Restarting the app doesn't help. But, if the user opens MS Word, types a few chars and then restarts my app, it operates normally.
One of the machines is a laptop running WinXP home and the other is a Desktop running Win98.
I am using JRE 1.4.2_05 as the runtime and Swing for the UI components.
The only parts of my code I can think of that may interfere with keyboard processing are:
I have a KeyEventPostProcessor which checks for the escape key nad arrow keys
I also have an event processor which looks like this:
     private static final class EventProcessor extends EventQueue {
          public EventProcessor() {
          protected void dispatchEvent(final AWTEvent evt) {
               try {
                    super.dispatchEvent(evt);
               catch (Exception e) {
                    // Catch any uncaught AWT Exceptions
                    try {
                         MedEDI.showException(e);
                    catch (Exception ignored) {
                    getInstance().shutdown();
     }I'm completely foxed as I cannot recreate this in my development environment. Has anyone else come across a similar issue?

Some possibilities:
1. Dirt under the keysIt is only my app (the only java app on the system) that has this trouble, which makes it unlikely that dirt is causing the problem. At one stage I thought that it might be a USB keyboard or keyboard driver problem, but given that one of them is a laptop with XP and the other is a desktop with 98, this seems unlikely too. Especially seeing that the other 8 terminals are all the same hardware and setup as the desktop.
2. Badly-programmed spyware installedNever thought of that. Might not be the problem, but what the hey, it's worth a try. I'll have them check for spyware on Monday and I'll let you know how it turns out.

Strange repaint behaviour with JList & Keyboard actions

Hi everyone,
This is my first post to the forum. You guys have been a great help in the past and I hope to contribute more in the future.
Anyways, I've encountered some strange repainting behaviour with a JDialog that uses a JList and a JButton. The dialog is fairly straight-forward and basically this is how it works (like an open file dialog - yes I'm implementing my own filechooser of sorts):
* JList lists a number of simple items that the user can select from.
* Once a selection is made, an Open button (JButton) is enabled.
* <ENTER> key is registered (using registerKeyboardAction()) with a JPanel which is used as the main content pane in the dialog.
* The user can either click on the Open Button or hit the <ENTER> key which then closes the dialog and runs whatever logic that needs to.
Now, the repaint problem comes in when:
1. User selects an item.
2. User hits the <ENTER> button
3. Dialog closes
4. User brings the dialog back up. This entails reloading the list by removing all elements from the list and adding new ones back in.
5. Now... if the user uses the mouse to select an item lower in the list than what was done in step #1, the selection is made, but the JList doesn't repaint to show that the new selection was made.
I didn't include a code sample because the dialog setup is totally straight-forward and I'm not doing anything trick (I've been doing this kind of thing for years now).
If I remove the key registration for the <ENTER> key from the dialog, this problem NEVER happens. Has anyone seen anything like this? It's a minor problem since my workaround is to use a ListSelectionListener which manually calls repaint() on the JList inside the valueChanged() method.
Just curious,
Huy

Oh, my bad. I'm actually using a JToggleButton and not a JButton, so the getRootPane().setDefaultButton() doesn't apply because it only takes JButton as an input param. I wonder why it wasn't implemented to take AbstractButton. hmmm.

Strange memory behaviour using the System.Collections.Hashtable in object reference

Dear all,
Recently I came across a strange memory behaviour when comparing the system.collections.hashtable versus de scripting.dictionary object and thought to analyse it a bit in depth. First I thought I incorrectly destroyed references to the class and
child classes but even when properly destroying them (and even implemented a "SafeObject" with deallocate method) I kept seeing strange memory behaviour.
Hope this will help others when facing strange memory usage BUT I dont have a solution to the problem (yet) suggestions are welcome.
Setting:
I have a parent class that stores data in child classes through the use of a dictionary object. I want to store many differenct items in memory and fetching or alteging them must be as efficient as possible using the dictionary ability of retrieving key
/ value pairs. When the child class (which I store in the dictionary as value) contains another dictionary object memory handeling is as expected where all used memory is release upon the objects leaving scope (or destroyed via code). When I use a system.collection.hashtable
no memory is released at all though apears to have some internal flag that marks it as useable for another system.collection.hashtable object.
I created a small test snippet of code to test this behaviour with (running excel from the Office Plus 2010 version) The snippet contains a module to instantiate the parent class and child classes that will contain the data. One sub will test the Hash functionality
and the other sub will test the dictionary functionality.

Next

Hi Cor,
Thank you for going through my post and took the time to reply :) Most apreciated. The issue I am facing is that the memory is not reallocated when using mixed object types and is not behaving the same. I not understand that .net versus the older methods
use memory allocation differently and perhaps using the .net dictionary object (in stead of the scripting.dictionary) may lead to similar behaviour. {Curious to find that out -> put to the to do list of interesting thingies to explore}
I agree that allocated memory is not a bad thing as the blocks are already assigned to the program and therefore should be reallocated with more performance. However the dictionary object versus hashtable perform almost identical (and sometimes even favor
the dictionary object)
The hashtable is clearly the winner when dealing with small sets of data.
The issue arises when I am using the hash table in conjunction with another type, for example a dictionary, I see that the dictionary object's memory is stacked on top of the claimed memory space of the hashtable. It appears that .net memory allocation and
reuse is for .net references only. :) (Or so it seems)
In another example I got with the similar setup, I see that the total used memory is never released or reclaimed and leakage of around 20% allocated memory remains to eventually crash the system with the out of memory message. (This is when another class
calls the parent class that instantiates the child class but thats not the point of the question at hand)
This leakage drove me to investigate and create the example of this post in the first place. For the solution with the class -> parent class -> child class memory leak I switched all to dictionaries and no leakage occurs anymore but nevertheless thought
it may be good to share / ask if anyone else knows more :D (Never to old to learn something new)

Strange Finder behaviour since installing Mountain Lion

I've been experiencing some strange finder behaviour since updating to Mountain Lion. Folders take several seconds to open after clicking on them (and sometimes won't open at all) and files cannot be moved around the desktop or dragged on to an app. However, it is possible to open a file by clicking on it. I've tried re-booting with Snow Leopard and everything seems OK, but as soon as I go back to ML, the problem starts again.

Library is a folder, not a file. There're more than one Library folders, one at the root and one for each user in your Mac. All of them are hidden, this is why you can't find them. But you can see their contents using
Finder Menu > Go > Go to Folder
And then type:
~/Library
for your Library Folder
-or-
/Library
for the root Library folder.

Oh, my bad. I'm actually using a JToggleButton and not a JButton, so the getRootPane().setDefaultButton() doesn't apply because it only takes JButton as an input param. I wonder why it wasn't implemented to take AbstractButton. hmmm.

Strange JTable behaviour - everything is highlighted

Hello all,
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,

Strange POF behaviour in 3.6.1.3

Hi All,
We have been seeing some strange POF behaviour in 3.6.1.3 paricularly around classes with boolean fields.
Here is my test case:
package org.gridman.pof;
import com.rbs.odc.dashboard.server.cluster.model.Case;
import com.tangosol.io.pof.ConfigurablePofContext;
import com.tangosol.io.pof.PofReader;
import com.tangosol.io.pof.PofWriter;
import com.tangosol.io.pof.PortableObject;
import com.tangosol.io.pof.reflect.PofValue;
import com.tangosol.io.pof.reflect.PofValueParser;
import com.tangosol.io.pof.reflect.SimplePofPath;
import com.tangosol.util.Binary;
import com.tangosol.util.ExternalizableHelper;
import java.io.IOException;
public class JK implements PortableObject {
    private String stringField;
    private boolean booleanFieldOne;
    private boolean booleanFieldTwo;
    public JK() {
    public JK(boolean booleanFieldOne, boolean booleanFieldTwo, String stringField) {
        this.booleanFieldOne = booleanFieldOne;
        this.booleanFieldTwo = booleanFieldTwo;
        this.stringField = stringField;
    @Override
    public void readExternal(PofReader pofReader) throws IOException {
        stringField = pofReader.readString(0);
        booleanFieldOne = pofReader.readBoolean(1);
        booleanFieldTwo = pofReader.readBoolean(2);
    @Override
    public void writeExternal(PofWriter pofWriter) throws IOException {
        pofWriter.writeString(0, stringField);
        pofWriter.writeBoolean(1, booleanFieldOne);
        pofWriter.writeBoolean(2, booleanFieldTwo);
    public static void main(String[] args) {
        ConfigurablePofContext pofContext = new ConfigurablePofContext("jk-pof-config.xml");
        JK value = new JK(false, true, "JK");
        Binary binary = ExternalizableHelper.toBinary(value, pofContext);
        PofValue pofValue = PofValueParser.parse(binary, pofContext);
        PofValue childOne = new SimplePofPath(0).navigate(pofValue);
        PofValue childTwo = new SimplePofPath(1).navigate(pofValue);
        PofValue childThree = new SimplePofPath(2).navigate(pofValue);
        System.out.println(childOne.getValue());
        try {
            System.out.println(childTwo.getValue());
        } catch (Exception e) {
            System.out.println("Exception: " + e.getMessage());
        try {
            System.out.println(childThree.getValue());
        } catch (Exception e) {
            System.out.println("Exception: " + e.getMessage());
}and the jk-pof-config.xml file used above...
<pof-config>
    <user-type-list>
        <include>coherence-pof-config.xml</include>
        <user-type>
            <type-id>3001</type-id>
            <class-name>org.gridman.pof.JK</class-name>
        </user-type>
    </user-type-list>
</pof-config>When you run the main method of the class above you would expect to get
JK
false
true... but what you get is...
JK
null
Exception: -34 is an invalid typeWhat is going on? The booleanFieldOne seems to have been serialized as type -34 which is PofConstants.V_BOOLEAN_TRUE which makes sense but the code to deserialize the field cannot handle type -34. The booleanFieldTwo comes back as null and is serialized as type -65 which is PofConstants.T_UNKNOWN
Where this causes us a problem is if we do a query with a filter like this...
new EqualsFilter(new PofExtractor(null, 1), true);...it will break whenever it tries to extract the POF value where booleanFieldOne is true.
I know we can fix this by always specifying the type, so this will work
new EqualsFilter(new PofExtractor(Boolean.class, 1), true);and this will work too wheras it fails without specifying the type...
childTwo.getValue(Boolean.class);So although there are work-arounds it seems very strange.
What is even stranger is that if you do not serialize the stringField so the readExternal and writeExtrnal methods look like this
@Override
public void readExternal(PofReader pofReader) throws IOException {
    //stringField = pofReader.readString(0);
    booleanFieldOne = pofReader.readBoolean(1);
    booleanFieldTwo = pofReader.readBoolean(2);
@Override
public void writeExternal(PofWriter pofWriter) throws IOException {
    //pofWriter.writeString(0, stringField);
    pofWriter.writeBoolean(1, booleanFieldOne);
    pofWriter.writeBoolean(2, booleanFieldTwo);
}The you get this output...
null
false
Exception: -34 is an invalid typeiNow the stringField is null (as we have not serialized it) but the booleanFieldOne is now being desrialized correctly as a boolean false. We have noticed that if you have a boolean as the first field you serialize in the writeExternal method then it is serialized as POF type -11 which is PofConstants.T_BOOLEAN and will be deserialized as the correct true or false value.
Cheers,
JK

Hi René,
Just changing the field types to Boolean like this...
private Boolean booleanFieldOne;
private Boolean booleanFieldTwo;made no difference. But then changing the writeExternal method to use writeObject instead of writeBoolean did fix it and the types of both fields are -11 or PofConstants.T_BOOLEAN
@Override
public void writeExternal(PofWriter pofWriter) throws IOException {
    pofWriter.writeString(0, stringField);
    pofWriter.writeObject(1, booleanFieldOne);
    pofWriter.writeObject(2, booleanFieldTwo);
}So using writeObject instead of writeBoolean would be another fix, but obviously most people would pick writeBoolean to store a boolean value.

Strange JFRAME behaviour under Jdk 1.5

I have the following extracted code :
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import java.awt.geom.*;
public class DrawPie extends JFrame{
     private HashMap ColourMap=new HashMap();;
     private HashMap DataMap=new HashMap();
     private double Total_Val=0;
     private int startAngle=0;
     private int arcAngle=0;
     public DrawPie(HashMap DataMap){
     super ("Pie Chart Analysis");
          this.DataMap=DataMap;
     //     System.out.println("DATAMap-->"+DataMap);
     // getContentPane().setBackground(Color.white);
          setSize(500,500);
          setVisible(true);
     public void paint(Graphics g){
          super.paint (g);
          Graphics2D g2 = (Graphics2D) g;
          DrawPieChart(g);
This programme work fine under jdk1.4.2 or below at the time when the Jframe or windows is resized or icon minimised or maximised.
But when it was compiled using latest jdk1.5 , unexpected strange result happen , the pie chart draw using java 2d
g2.fill(new Arc2D.Double(30, 30, 200,200,startAngle,arcAngle
, Arc2D.PIE));
wil behaved strangely, the moment the JFrame or windows is resize or dragged.
The pie chart will disappear if the windows is resized , However if the window is minimised and restore back to normal size , pie chart will reappear and subsequently lost completely if the windows is dragged resulted in the size changes.
I was puzzled by this strange swing behaviour , any resized or windows minimise or maximise would not result in the lost of pie chart as long as the jdk is not 1.5 ! Was it due to swing fundamental changes incorporated in the latest release?
Any suggestion?
Thank

ok I see what you have done,
now a few tips in drawing something on your frame:
never override the paint method of your main Frame (like you did)
to draw something on it you simply override the contentPane's paint method
and to make your own contentPane you simply make one by making a new Class
that extends say JPanel and assign it as a contentPane of your Frame(like I did)
And in this Paint method you can draw whatever you like it will be properly uptated!!!
All the best keep up the good work!
ps. try the code bellow.
import javax.swing.*;
public class DrawPie1 extends JFrame {
private double Total_Val=0;
private int startAngle=0;
private int arcAngle=0;
private MyMainPanel mainPan;
public DrawPie1()
super ("Pie Chart Analysis");
mainPan = new MyMainPanel();
setContentPane(mainPan);
//public void paint(Graphics g) //Do not override the paint method of your main frame!!
// super.paint (g);
// Graphics2D g2 = (Graphics2D) g;
// g2.setPaint(Color.red);
// g2.fill(new Arc2D.Double(30, 30, 200,200,0,78
// , Arc2D.PIE));
public static void main(String args[])
DrawPie1 pie=new DrawPie1();
pie.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pie.setSize(400,300);
pie.setVisible(true);
//**** Second Class
import javax.swing.*;
import java.awt.*;
import java.awt.geom.Arc2D;
public class MyMainPanel extends JPanel
public MyMainPanel()
public void paint(Graphics g)
super.paint (g);
Graphics2D g2 = (Graphics2D) g;
g2.setPaint(Color.red);
g2.fill(new Arc2D.Double(30, 30, 200,200,0,78
, Arc2D.PIE));
}

Sourcing 7.0 - Strange Login Behaviour for enterprise user

Hello
We have installed SAP Sourcing 7.0 and created one tenant and after that everything was running fine. I have now created another tenant. After this there is a strange login behaviour for enterprise user
When I go to the ...../fsbuyer/portal URL, it given me a login screen. When I try to login with enterprise user and password as specified in the context, it does not let me login even with a correct password. The error is "User Authentication Failed"
I just happened to try NW CE Administrator Login, after this the error changed to "Entry does not exist". Here I gave enterprise user and password and it logged into the system. So I now have to login two times once with NW UME User and other with enterprise user to access the setup page.
However this is the problem only for enteprise user and not for other user accounts that I created. I checked in NW UME, the enterprise user does not exist there. However I can see that other users that I created using "Internal User Accounts" are also created in NW UME.
Anyone faced this behaviour earlier?
This also brings out a very interesting point. In Multi-Tenant Setup when using NW UME does this mean that two tenants cannot share the same user account. Is that so?
Regards,
Shubham

Hi Vikram,
Thanks a ton for your reponse.
I would like to understand your solution regarding creating another cluster.
Does this mean I need to install another CE Instance and install sourcing on the same.
OR
I have to create an Add-In instance for the current CE Server and define the Host Name of Add-In Instance in the new cluster
Also in this cluster, which context should I select, System Context or Existing Tenant Context or New Tenant Context.
Regards,
Shubham
