Hi Shumar,

I just updated to Eclipse 3.4.1 for this very reason.

The known work around is to close your model and reopen it immediately to create the new relationship. YOU have done nothing wrong ;-)

This is a known bug (see comments for mention of the relationship wizard) <http://issues.objectstyle.org/jira/browse/WOL-841> that I understand it won't be fixed in the "prior to new hotness" versions of WOLips. I have filed a bug against Eclipse 3.4.1 yesterday, <http://issues.objectstyle.org/jira/browse/WOL-969> but I am finding it happens much less in the nightly/stable versions of WOLips which *require* Eclipse 3.4.1 and change your projects' structure when you upgrade your workspace. Make sure you read up on the impacts to your projects before you make the decision to upgrade.

David

Hi Group,

I have two entities: Customer & Sales.

Am trying to establish a relationship from Entity Modeler between these two entities with following cardinality: Customer <----->> Sales

After selecting the destination entity, it is defaulting attributes and required relationship cardinality properly in the dialog box. But when I click 'OK', it results in below error and is not creating any relationship as instructed. Could anyone help me out whatz wrong here?

Eclipse Version: 3.3.1.1
WO: 5.3.*
