[SOLVED] Paren - Automatic System Construction
Contributor II
Hi,
I'm experiencing an error when starting "Automatic System Construction" with the Paren extension complaining about XML issues.
A couple of other people seem to be having similar (but not identical) issues and have resurrected an old thread here: http://rapid-i.com/rapidforum/index.php/topic,2916.msg17207.html#msg17207
Due to the age of that thread, I think a new topic for the current issue might be useful.
I'm running RapidMiner on Ubuntu, no other extensions installed and apparently fully updated.
The exact error seems to be different for us, my error is shown in the attached screenshot: http://image.bayimg.com/ganhmaadb.jpg
.
I have logged this as bug 1048: http://bugs.rapid-i.com/show_bug.cgi?id=1048
Starting Rapidminer from a console generated a log which is here:

Having deleted the installation and reinstalled to 5.2.001, the error continues but is slightly different. Still basically the same but now the same as reported by others: java.io.IOException: Cannot read from XML stream, wrong format: org/xmlpull/v1/XmlPullParserFactory
The log from a console start is below:
unfortunately we are not maintaining the Paren extension but i have found the error. With the last release 5.2.1 we have updated the in RapidMiner included xstream library to version 1.4.2.
With this version it is not possible to use the xmlpull library without referencing it when building the .jar. The Paren extension does not seem to reference this library.
Please contact the developers of the Paren extension (http://madm.dfki.de/rapidminer/wizard) and ask them to release a new version with xmlpull referenced.
Best,
Nils
we have decided to add the library in our next release. No need to contact the developers anymore.
The release should take place tomorrow or one day later.
Best,
Nils
I look forward to the update.

I have downloaded the new version, but it has a new bug:
when you run the PaREn, you will see an empty "Error" dialog box with just a close button. And the PaREn does not work at all. If you press the close button, PaREEn will be closed!!!
I hope RM team solve this problem as soon as possible. Because PaREn is a very nice and necessary piece of software which grately helps RM power.
Thanks
With that said, I've also noticed it and logged it in bugzilla: http://bugs.rapid-i.com/show_bug.cgi?id=1063
I've also notified dfki.de and they said they'll look at it "within the next days".
This error only effects the Automatic System Construction. The Landmark operator still works fine so at least there's that.
If you want to make a new thread for this error, feel free though I think it's being handled.
