Description Fabio Zadrozny

2011-02-22 12:23:29 EST

Build Identifier: M20100909-0800

When trying to get the markers from the workspace root (i.e.: container.findMarkers(PyBreakpoint.PY_CONDITIONAL_BREAK_MARKER, true, IResource.DEPTH_INFINITE),

a ClassCastException is being raised.

The full stack trace is:

Comment 1 Clayton Keller

Here is additional information regarding my environment and reproducing the issue.

Fedora Core 14 x86_64
Pydev: 1.6.5.2011020317
Pyton: 2.7
eclipse.buildId=M20100909-0800
java.version=1.6.0_20
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US
Command-line arguments:  -os linux -ws gtk -arch x86_64

I am trying to execute a python file in Debug when the error reported by Fabio occurs. This happens on any attempt to debug the file. The file is executed however the change to debug view does not occur as due to the "Error setting breakpoints" error that happens.

I have same Exception, different stack trace. Exception occurs on startup and with virtually every UI event that is fired. I am looking through error log for additional information, but here is a stack trace.

Comment 4 henry noerdlinger

This appears to be related to breakpoints. 
1) delete a bunch of breakpoints. 
2) add a few new ones
3) shutdown eclipse
4) start eclipse back up


also in error log:
Could not create action delegate for id: org.eclipse.debug.ui.actions.RemoveAllBreakpoints

(In reply to comment #1)

I believe after additional testing the root issue for me was permissions between root and non-root accounts.

I have performed a clean install into a non-root users folder and am able to debug without generating any type of error.

It's been a few years after this report and I haven't gotten it anymore, so, closing it.
