I made an IPartListener so when I change between different file types I can change perspective automatically. But when I drag an editor tab to a new location, it iterates over the other tabs it crossed. Now I think because of this, the editors getting activated and eclipse wants to change perspectives too fast. And I get a new tab added named: Drag Placerholder which is an ErrorViewPart.
My code:
PlatformUI.getWorkbench().getDisplay().asyncExec(() -> {
IWorkbenchWindow workbenchWindow = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
workbenchWindow.getPartService().addPartListener(new IPartListener() {
#Override
public void partActivated(IWorkbenchPart part) {
if (part instanceof MyEditor && MyEditor.isAutomaticPerspectiveChangeEnabled()) {
MyEditor editor = (MyEditor) part;
try {
editor.changePerspective();
} catch (WorkbenchException e) {
ErrorHandler.handleUnexpectedError(e);
}
}
}
}
}
I attached some pics, if I drag file1.abc after file3.xyz and the files between would use other perspective, I end up with a 4th tab and a NullPointerException
I'm not sure why Eclipse is activating the tabs between the drag points, can I somehow block that?

When i try to create web service Its show like that error. I used Apache CXF 2.X for this task.
I tried to do bellow this
Windows-->Preferences-->Add-->Added CXF 2.x
But problem wasn't solve.
Here is my Interface code
#WebService
public interface ISubstraction {
public int substract(int x, int y)
}
Here is my implementation code
#WebService(endpointInterface ="com.webservice.ISubstraction")
public class SubstractionImpl implements ISubstraction {
#Override
public int substract(int x, int y) {
int z = x-y;
return z;
}
}
Here is exception

If u have idea please give me answers.Thank you
In my Eclipse 4 RCP App I want to dispose some CTabFolders. I check if they are already disposed and if not I dispose them. But it still raises an SWTException: Widget is disposed.
I checked if every CTabFolder in stageDataTabFolders is unique.
Here is the code fragment:
for (Tuple<CTabItem, CTabFolder> stageDataTabFolder : stageDataTabFolders) {
if (!stageDataTabFolder.getSecond().isDisposed()) {
stageDataTabFolder.getSecond().dispose();
}
}
And the Exception:

Edit: I created them like this:
CTabFolder stageTabFolder = new CTabFolder(parent, SWT.BORDER | SWT.FLAT);
stageTabFolder.setSimple(false);
stageTabFolder.setTabPosition(SWT.BOTTOM);
CTabFolder stageDataTabFolder = new CTabFolder(stageTabFolder, SWT.TOP);
stageDataTabFolder.setSimple(false);
stageDataTabFolders.add(new Tuple<CTabItem, CTabFolder>(stageTabItem,
stageDataTabFolder));
Edit: The whole purpose is to implement a menu Item "New" to reset the App back into a virgin state. The call goes like this:
#Execute
public void resetEditor(MApplication app, IWorkbench workbench) {
MPart configPart = partService
.findPart("de.uni_due.s3.jack.editor.parts.config");
MPart stagePart = partService
.findPart("de.uni_due.s3.jack.editor.part.stage");
resetHandler();
((StagePart)stagePart.getObject()).dispose();
partService.activate(configPart);
}
On the StagePart:
public void dispose() {
for (Tuple<CTabItem, CTabFolder> stageDataTabFolder : stageDataTabFolders) {
if (!stageDataTabFolder.getSecond().isDisposed()) {
stageDataTabFolder.getSecond().dispose();
}
}
stageDataTabFolders.clear();
stageTabFolder.dispose();
}
I have a keyboard emulation class which has a method to type to the Eclipse editor automatically based on voice recognition input. This works correctly.
I also have tables made in JavaFX, in which a user clicks an element and it too is emulated to the screen using the same method.
However, I am getting "Exception in thread "JavaFX Application Thread" java.lang.NullPointerException" exceptions. This does not happen from the voice recognition part, only when the JavaFX thread calls the method to update the Eclipse editor.
Keyboard Emulation method which prints data to the eclipse text editor
private void doType(int[] keyCodes, int offset, int length) {
if (length == 0) {
return;
}
//Since we are in a loop, we must only emulate the mouse press on the eclipse
//text editors last known location to avoid every letter getting mixed up
correctCaretPosition++;
Display.getDefault().syncExec(new Runnable() {
public void run() {
System.out.println("fwefwefwef\n\n\n\n\n\n" + myEditor.PROP_DIRTY);
Control control = myEditor.getAdapter(Control.class);
//Only when the click to bring eclipse into scope has not happened
if (control instanceof StyledText && correctCaretPosition <= 1) {
StyledText text = (StyledText)control;
// Position of caret relative to top left of the control
Point relPos = text.getLocationAtOffset(text.getCaretOffset());
// Position relative to display
Point absPos = text.toDisplay(relPos);
System.out.println(absPos.x + " " +absPos.y);
robot.mouseMove(absPos.x, absPos.y);
robot.mousePress(BUTTON1_MASK);
robot.mouseRelease(BUTTON1_MASK);
}
robot.keyPress(keyCodes[offset]);
doType(keyCodes, offset + 1, length - 1);
robot.keyRelease(keyCodes[offset]);
}
});
}
JavaFX call to Keyboard Emulation
Platform.runLater(new Runnable() {
#Override
public void run()
{
robot.type(data);
}
});
The error comes from this line
Control control = myEditor.getAdapter(Control.class);
Robot in this context is the Keybooard Emulation object.
Am I getting the concurrency between the two completely wrong?
UPDATE:
The root of the error is
Control control = myEditor.getAdapter(Control.class);
I passed in the control from the beginning of the application, no error, however, nothing happens as I believe the control does not satify
if (control instanceof StyledText && correctCaretPosition <= 1) {

When I open "EditAwardsView1" for the first time the Window.alert displays once. I enter data, select the "Save" button and my save to the DB occurs once. So far so good.
However, I then go back to the previous view "SelectPerson" and then open "EditAwardsView1" a second time. This time Window.alert displays twice and I get one "Uncaught exception escaped" error. I enter data, select the "Save" button and my save to the DB occurs twice.
If I repeat this again (go back to "SelectPerson" and then back to "EditAwardsView1") Window.alert displays five times and I get four "Uncaught exception escaped" errors. I enter data, select the "Save" button and my save to the DB occurs five times.
The calling code from the "SelectPerson" view is:
btnEditAward.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
navHandler2.go("EditAwards1");
}
});
btnEditAward.setStyleName("gwt-PushButton-up");
btnEditAward.setText("Edit Awards");
btnEditAward.setWidth("184px");
btnEditAward.setHeight("40px");
horizontalPanel.add(btnEditAward);
The entry point in "EditAwards1" is:
public EditAwardsView1(final NavHandler navHandler) {
rpc = (DBConnectionAsync) GWT.create(DBConnection.class);
ServiceDefTarget target = (ServiceDefTarget) rpc;
String moduleRelativeURL = GWT.getModuleBaseURL() + "MySQLConnection";
target.setServiceEntryPoint(moduleRelativeURL);
navHandler2 = navHandler;
//On load of page get the stored view data
//TODO Fix null pointer on reload.
verticalPanel.addAttachHandler(new Handler() {
int pog = 0;
public void onAttachOrDetach(AttachEvent event) {
if (pog == 0) {
pog++;
verticalPanel.clear();
listBoxAwardType.clear();
awardGrouped = null;
Window.alert("EditAwardsView1.");
//Retrieve stored data for this view.
AsyncCallback<ViewData> callback = new ViewDataHandler2<ViewData>(EditAwardsView1.this);
rpc.getViewData(callback);
}else{
pog = 0;
}
}
});
initWidget(verticalPanel);
}
The calling code from "EditAwardsView1" to return to the "SelectPerson" view is:
//Button btnSelectYouthMember = new Button("Select Youth Member");
btnSelectYouthMember.setStyleName("gwt-PushButton-up");
btnSelectYouthMember.setText("Select Youth Member");
btnSelectYouthMember.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
navHandler2.go("SelectPerson");
}
});
btnSelectYouthMember.setWidth("184px");
btnSelectYouthMember.setHeight("40px");
horizontalPanel_Menu.add(btnSelectYouthMember);
The error is:
[ERROR] [org.AwardTracker.AwardTracker] - Uncaught exception escaped

Please see http://forums.whirlpool.net.au/forum-replies.cfm?t=2265752 for an answer.
In short I:
deleted NavHandler.java,
changed AwardTracker.java to allow for history and remove need for NavHandler.java,
changed new view call to History.newItem("selectPerson", true);
added the test if (event.isAttached()) to the AttachHandler and
moved the following code into the AttachHandler -
rpc = (DBConnectionAsync) GWT.create(DBConnection.class);
ServiceDefTarget target = (ServiceDefTarget) rpc;
String moduleRelativeURL = GWT.getModuleBaseURL() + "MySQLConnection";
target.setServiceEntryPoint(moduleRelativeURL);

I am creating an android app and needed to change the text of some textViews in one of my layouts. This is my code.
public void hudSetup() {
Player stats = new Player(this);
stats.open();
String playerName = stats.getStringField(stats.KEY_NAME);
String playerCity = stats.getStringField(stats.KEY_CITY);
int playerHealth = stats.getIntField(stats.KEY_HEALTH);
int playerEnergy = stats.getIntField(stats.KEY_ENERGY);
int playerRank= stats.getIntField(stats.KEY_RANK);
int playerCash = stats.getIntField(stats.KEY_CASH);
stats.close();
name.setText(playerName);
city.setText(playerCity);
energy.setText(playerEnergy);
health.setText(playerHealth);
cash.setText(playerCash);
rank.setText(playerRank);
}
I have ensured all of my textViews are initialised. The code compiles, however when i run the app and the hudSetup() method runs, I get a nullPointerException.

What am I doing wrong? Any help will be appreciated.
Thank you!
TextView.setText(int) uses the resource defined as an integer in R.java.
For your purpose, you might want to cast the integers to String first.
Like:
cash.setText(playerCash + "");
Or, like #Pedro said:
cash.setText(String.valueOf(playerCash));
