Bug 70077 [typing] Copy/paste doesn't work occasionally
Hi. When I do the copying/pasting, something seems strange: I'm editing the Java source code, and want to copy some lines of code to another place, I selected the lines, about 15-line, press Ctrl-C, and then move to the paste place, and press Ctrl-V, and just nothing happened. I've tried several time, and tried to use mouse and right-button-menu for the copy/paste, the results are the same. And I also tried to copy/paste only one line, it sometimes works, but not always. With multiple lines copy/paste, it sometimes works too. I'm using the Eclipse 3, Windows 2000 pro, JDK 1.4.2, Lomboz.3rc2(before), Lomboz 3(now).

return shell;

		return null;

	private Display getDisplay() {
		Shell shell= getShell();
		if (shell != null) {
			return shell.getDisplay();
		}
		return null;
	}
	
	
	protected final void internalDoOperation() {
		if (PreferenceConstants.getPreferenceStore().getBoolean(PreferenceConstants.EDITOR_IMPORTS_ON_PASTE)) {
			if (fOperationCode == ITextOperationTarget.PASTE) {
				doPasteWithImportsOperation();
			} else {
				doCutCopyWithImportsOperation();
			}
		} else {
			fOperationTarget.doOperation(fOperationCode);
		}
	}
