Hi all,

I am using the convert CSV to XES plugin to convert a big(15,3GB) csv file of an event log to XES.
When running the conversion I get the following error (Pasted with some context):
Pre-sorting finished segment 331 ...
Sorting finished round 1/4 ...
Sorting finished round 2/4 ...
Finished sorting in 1471 seconds
Reading cases ...
java.lang.NullPointerException

When running ProM from the .bin the console gives me the following feedback:

-------- The following exception was logged by the framework:
         The exception was probalby handled properly.

Can anyone help me identify what the problem is?

Edit:
-I'm running prom 6.5.1.
-I read in another discussion on this plugin that I could try the nightly build. I can however not find a nightly build I can get to run.

Thanks in advance!

    Hi JvdW,
    Could you please try out the nightly build (obtainable here http://www.promtools.org/doku.php?id=nightly) or ProMLite (http://www.promtools.org/prom6/downloads/prom-lite-installer.exe)?

    The issue with the standard ProM releases (like 6.5, ..) is that we are not allowed to update packages (for reproducible experiments) and I know that there are some bugs in the CSV importer of 6.5 and 6.5.1. ProMLite will update itself from time to time, but it is limited to some standard plug-ins.

    Another option would be to not use the "start timestamp" feature. Just deselect the "start timestamp column" and use the "complete timestamp column" instead. If I remember correctly this bug occured when only a start timestamp column without a complete timestamp column is selected.

    I hope this helps.
