[jboss-user] [JBoss jBPM] - JBPM fails to evaluate expression in pageflow decision after

[mrwaves]

Environment configuration: JBoss Seam 1.2.1.GA, JBoss Server 4.0.5.GA, JBoss Eclipse IDE 2.0.0.Beta2

I need to import about 2900 data records into a local database which takes about 30 minutes to complete.

With less than about 1700 records everything works fine: No error messages and all data records are written to db.

Bu as soon as I start importing more than ca 1700 data records (~17 minutes), I receive the following output (most interesting part only):


  | [...]

This just seems to affect the pageflow. All data records are written to the local db without any problems.

I already set TransactionTimeout in component.xml to 3600 sec (one hour!). 
The @Begin and @End annotations within the source code are placed correctly and the pageflow-definition diagram is also ok.

Is there any other timeout parameter I oversaw? I couldn't find any appropriate else.

Thanks in advance
