Hi all,

We're experiencing what looks like a displaytag error that I wonder if anyone knows about. The error occurs on appfuse 1.9.1, displaytag 1.1, webwork 2.2.2, MySQL 4.1.10a, SuSE Linux 9.3, JDK 1.5.6. On Windows XP professional, same appfuse and java software versions but MySQL 4.1.15 the error doesn't happen at all, which is interesting.

The bug happens when clicking the paging links using display tag to list ~600 fairly large "Customer" class instances that has a hibernate many-to-one relation to another pretty large class for Contacts (both have many fields). If I list only the Contacts or decouple the relationship between the Customer and Contact objects and list the Customers the error does *not* occur. Even though the hibernate relationship is many-to-one, with the Contact instance "embedded" within a property of the Customer instance, we never have an instance of the Contact class that is associated to > 1 Customer instance, so in practice it's kind of like a one to one situation. The other thing to note is that once the bug has occurred, the tomcat server must be restarted. I found this link talking about a display tag issue that requires a server restart but I'm not sure if this is the same bug:

http://jira.codehaus.org/browse/DISPL-370

Does anybody know anything about this and its resolution? Is it a displaytag error, or could it be MySQL or perhaps even webwork? (I suspect it's not webwork but I've not found anything on it so far so I'm not sure). Any help would be greatly appreciated, thanks!
