crash log

Happens on Carbon with latest build and OSX 10.6.
Couldn't reproduce it on OSX 10.5

Steps to reproduce:
1) Open the run configuration dialog.
2) Create an eclipse application.
3) select the plugins tab
4) select launch with 'plugins selected below only' in the combo box
5) In the search box (for type filter text) start typing the name of any plugin.
For me, it crashes when I type the 2nd character.
I can reproduce it consistently.

I see this, too, with basically the same stack trace. I'll have to find another Carbon app with a search field to see if it's an OS bug.
Comment 2 Scott Kovatch CLA 2010-05-11 13:16:09 EDT
ControlExample doesn't crash, FWIW.
Comment 3 Scott Kovatch CLA 2010-05-11 14:22:55 EDT
Seems to be limited to just this dialog. I can use a filter in the Install Updates dialog with no problems.
Comment 4 Scott Kovatch CLA 2010-05-11 15:00:25 EDT
It seems to be related to the fact that the search field is initially disabled when the window appears. When you select 'plugins selected below only', that enables the search field. When you click on the search field, notice that the caret doesn't appear right away. You have to click it a second time, and then the flashing insertion point appears. At that point you can start typing.

happens on 10.5 too.
Comment 6 Lakshmi P Shanmugam CLA 2010-05-12 10:13:22 EDT
I can reproduce it with a SWT snippet. When Text.setText is called in mouse down listener, the caret doesn't appear. Typing now into the textbox leads to crash.

public class Bug_312432 {
	public static void main(String[] args) {
		Display display = new Display();
		Shell shell = new Shell(display);
		shell.setLayout(new GridLayout(1, false));
		
		final Text text = new Text(shell, SWT.SINGLE | SWT.BORDER);
		text.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));
		text.setText("type text here");
		text.addMouseListener( new MouseAdapter() {
			public void mouseDown(MouseEvent e) {
				System.out.println("mouse down");
				text.setText("");
			};
			public void mouseUp(MouseEvent e) {
				System.out.println("mouse up");
//				text.setText("");
			};
		});
		shell.pack();
		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
		display.dispose();
	}
}

Doesn't happen on cocoa, its carbon only.
Closing report, platform is discontinued.
