Breakpoints not appearing on vertical ruler [message #285209]

Hello to everyone,

I'm having a problem with breakpoints not appearing on the vertical ruler
that I'm hoping someone can help me with.

I'm extending Eclipse for a new programming language. I created a debug
target, et all, pretty much identical to the PDA example in the eclipse
articles (from http://www.eclipse.org/articles/ - How to write an Eclipse
debugger). This problem appears with the source code provide for the PDA
example as well.

The problem is that when a breakpoint is set, it appears in the breakpoint
list, but does not appear in the ruler in the text editor. It does however
appear in the ruler if the source document is closed and reopened. Then if
the breakpoint is deleted, the icon disappears, but does not appear again
when a breakpoint is added again.

I've created my own editor (which extends TextEditor) which basically does
nothing more than TextEditor. I tried adding an IBreakpointsListener to the
breakpoint manager, and calling
getVerticalRuler().update();
getVerticalRuler().getControl().redraw();
each time a breakpoint is changed/added/deleted, but this has no effect
either.

Again, this problem also appears for the PDA example - any ideas on how
to solve it?

Thank you in advance,
Andrew

If I remember correctly this problem is solved by ensuring that you are
creating your breakpoints in an IWorkspaceRunnable.
See the AntLineBreakpoint (or any of the JDT Debug breakpoints) as an
example

I am working on the same tutorial and I have also the problem that the breakpoint marker is not shown in the vertical ruler.
Even if I close the editor and reopen it the icon is not shown. However the icon appears in the breakpoint view and
if I mouse over on the vertical ruler the text corresponding to the breakpoint marker is shown.
I am creating the breakpoints in an IWorkspaceRunnable:

public PDALineBreakpoint(final IResource resource, final int lineNumber)
			throws CoreException {
		IWorkspaceRunnable runnable = new IWorkspaceRunnable() {
			public void run(IProgressMonitor monitor) throws CoreException {
				IMarker marker = resource
						.createMarker("example.debug.core.pda.markerType.lineBreakpoint");
				setMarker(marker);
				marker.setAttribute(IBreakpoint.ENABLED, Boolean.TRUE);
				marker.setAttribute(IMarker.LINE_NUMBER, lineNumber);
				marker.setAttribute(IBreakpoint.ID, getModelIdentifier());
				marker.setAttribute(IMarker.MESSAGE, "Line Breakpoint: "
						+ resource.getName() + " [line: " + lineNumber + "]");
			}
		};
		run(getMarkerRule(resource), runnable);
	}

Can anybody explain how to show the blue circle?
