Tech:Troubleshooting

Before embarking on laborious debugging, try these steps. Your problem may have an easy solution.

Check file permissions. Subversion has a tendency to clobber permissions. Anything which needs to be web-accessible must be world-readable; this includes the SWF and many Python modules. If Python complains about not finding modules which clearly exist, or you get strange errors like "Invalid WFS operation 'GetFeature'", check your permissions. Reid's fixperms script (in the source tarball) can help with permissions repair.
Restart Apache.
Restart routed.
Rebuild flashclient.
Clear your browser’s cache: Tools, Clear Private Data on Firefox.
If you get "Property <FOO> not found on <FOO> and there is no default value", is it private but you think it's public?
