Hello!
I've introduced OpenEntityManager filter to my application and switched to
wicket 7.1.0 and all enclosures that worked perfectly before went crazy.
Here is a web xml snippet:
<filter>
<filter-name>open-entitymanager-in-view-filter</filter-name>
<filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>open-entitymanager-in-view-filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>TestWebApplication</filter-name>
<filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
<init-param>
<param-name>applicationClassName</param-name>
<param-value>com.test.rest.webapp.TestWebApplication</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>TestWebApplication</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Here is the exception I am getting:

Can anyone help? I'm a bit clueless. A workaround would work well enough.
To reiterate I'm using regular encolsures that work without a problem
before.
Thanks,
Peter
