Ok Update on this issue:

It seems to be a Bug in Magnolia when using one of the "no-search" 
configurations. I first assumed I made some mistake during Mysql configuration, 
so I made some testing with the original derby powered setup from the war files.

Using the standard installation (jackrabbit-derby-search.xml) it seems to work 
and the nullpointer and "failed to set up an iterator" does not appear.

Using the no search configuration (jackrabbit-derby-nosearch.xml) it takes one 
minute after bootstrapping until the log gets filled with some of the 
exceptions I mentioned.

So at this point I have the following questions:
- can this message be ignored? What does it mean?
- is there a way to work without the lucene index (lucene seems to be buggy 
when it comes to corrupt PDF files, and crashes the whole magnolia application, 
that's why)

Cheers

Claudio

Subject: [magnolia-user] Problem with Workflow Engine

Hi List

I downloaded and installed the newest magnolia (I used the war files).
In the log files I find strange errors regarding the Workflow. Shortly
after restart the log starts to fill with:

ERROR  info.magnolia.module.workflow.jcr.JCRExpressionStore
JCRExpressionStore.java(contentIterator:170) 01.03.2007 14:49:54

        at
openwfe.org.time.Scheduler$SchedulerThread.run(Scheduler.java:569)


My Setup is as follows:
- Tomcat
- Mysql
- The repo-Conf configfuratiopn file does not contain a tag for the
Lucene Index, because I do not want to use it.

Is there a scheduled tasks that runs in regular intervals and fails? Any
ideas how to fix this?

Thanks for helping

Cheers

Claudio
