Process not finding records produces Error 500

Hello !

I've just upgraded to Version 2.2. and everything seemed fine ....

When starting a process with the following actions

If EXISTS Warnung WHERE (Warnung.GiltBis>=CURRENT_DATE) Then DISPLAY MESSAGE 'Achtung es gibt aktuelle Warnungen' 
CREATE Bestellung WITH Bestellung.Kunde=ThisKunde,Bestellung.Datum=BUSINESS_DAY_FORWARD(CURRENT_DATE),Bestellung.Bemerkung=ThisKunde.Bemerkung 
VIEW Bestellung USING Main

Then AwareIM 2.2 Build 937 reproducible drops an Error 500 if the first action finds no records ! If the first action does find a record everything works fine.

The Output from AwareIM's log is:

Process status: Started
Unable to deserialize process context com.bas.basserver.executionengine.a; local class incompatible: stream classdesc serialVersionUID = 120896510790969603, local class serialVersionUID = -3954976629079359826

When upgrading from 2.0 to 2.2 I used the steps described here http://www.hiden.org/awareim/tips-n-tri ... er-version

Many thanks for your help !

Hi Hubertus,

you may need to manually cleanup one of the system tables - execution_contexts in BASDB and BASDBTEST databases. Could you delete all records in these tables and try again?

Hi aware_support !

Sorry but execution_contexts is empty.
Any other ideas on what could be wrong ?

In this case something is screwed up in your setup. Is it possible that your system somehow has two awareim.jar files? And somehow one of the scripts points to awareim.jar from the old version?

This is the only explanation I can think of for this problem.

I do have several backup copies on my system but definitly no script pointing there.
Additionally this behaviour is reproducible on 2 (Linux)systems.
The only thing that is is common to these 2 systems is that the database is a backup copy from the other system. But as I've said below the execution_contexts table is empty.

Can you send us the BSV file and describe the steps required to reproduce the problem?
