I’m using MyEclipse 5.0.1GA with Eclipse 3.2 on Windows XP Pro.

I’m getting an exception from content assist in the Hibernate mapping editor. It doesn’t happen the first time. It happens if I open a mapping file, use content assist (ctrl-space), close the file, open the file, and use content assist again. The problem persists until I close Eclipse and reopen. Here’s the exception stack trace from the Eclipse error log view:

What are the actual side effects of the problem? Assuming you couldn’t see what is getting written to the log, are you experiencing any other problems? (like autocomplete failing to work?)

gadams00,

I can’t reproduce your case.Could you send mapping xml for example

Thanks,

Yes, autocomplete fails to work thereafter.

Thanks,

Here’s the mapping file:

<?xml version=”1.0″?>
<!DOCTYPE hibernate-mapping PUBLIC
“-//Hibernate/Hibernate Mapping DTD 3.0//EN”
“http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd”&gt;

<hibernate-mapping package=”com.foo.persist” >

<class name=”Child” table=”CHI_CHILD” lazy=”true” >
<id column=”CHI_UID” name=”internalId” type=”long”>
<generator class=”native” />
</id>
<property column=”CHI_ID” name=”childId” type=”string”
length=”32″>
</property>

<many-to-one column=”CHI_PAR_UID” name=”parent” class=”Parent”/>
</class>

</hibernate-mapping>

I tried some more stuff and can’t reliably reproduce either. One way to get it to happen most of the time is to close the mapping editor before the second pane of the content assist shows on screen, then reopen and try to use content assist. Just keep trying to open, use content assist, and use various combinations of saving and discarding changes to the mapping file and reopening and closing the editor. I can easily get it to happen in a minute or so.
