#72 Exception error, duplicates are not permitted

[Rick Tanner]

Using statsvn-0.3.1

I am encountering the following error:

Exception in thread "main" org.jfree.data.general.SeriesException: You are attempting to add an observation for the time period Sun Nov 04 01:50:00 CST 2007 but the series already contains an observation for that time period. Duplicates are not permitted. Try using the addOrUpdate() method.

Checking the SVN Log file indicates only one checking at that day & time.

Is this an internal error with the application?

Another note - statsvn does not generate any graphs or content after encountering this issue. Just the following 2 files:

jtreemap-1.1.0.jar
repomap-data.txt

It then kicks me back to the shell prompt.

The error you list above doesn't seem to be related to the code in StatSVN. We inherit this functionality from StatCVS. Further investigation is required.

It is typically a JFreeChart exception. It would be very useful if you could identify the chart that it is trying to create. Is there a more comprehensive exception with a stacktrace?
Could you do a dump of your repository using StatSVN and check whether there is more than 1 entry for that timestamp?
Thanks

Do you mean, this?

There is only one entry AFAICS

Interesting, the manifestation of your issue is in StatCVS. Before we go and modify it (may be a valid point to do addOrUpdate) we should chekc that StatSVN does interpret your repository correctly. Could you run statSVN -dump? see manual:
http://svn.statsvn.org/statsvnwiki/index.php/User_Manual

Zip and attach the result
