Subject [jira] Created: (OPENJPA-139) PersistenceException merging an entity with a Calendar field.
Date Fri, 09 Feb 2007 00:20:05 GMT
PersistenceException merging an entity with a Calendar field. 
--------------------------------------------------------------

                 Key: OPENJPA-139
                 URL: https://issues.apache.org/jira/browse/OPENJPA-139
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
            Reporter: Michael Dick


I get the following exception when I try to merge an entity which contains a java.util.Calendar
field. 

<0|true|0.0.0> org.apache.openjpa.persistence.PersistenceException: mikedd.entities.CalendarEntity.cal
	at org.apache.openjpa.kernel.AttachStrategy.attachField(AttachStrategy.java:255)

I'm running the test in eclipse and my classpath probably isn't set up to properly display
the openjpa version, 
output from svnversion -c : 406193:505052M

It looks like we're missing a case statement for JavaTypes.CALENDAR in org.apache.openjpa.kernelAttachStrategy.attachField.
I added one under JavaTypes.DATE and that resolved the issue for me.
