Hello Martin,
the problem is that i assign a model in request cycle metadata by using the key
public class IdentityInstance extends MetaDataKey<IModel<Identity>> {
public static IdentityInstance KEY = new IdentityInstance();
private IdentityInstance() {
super();
}
}
Page:
getRequestCycle().setMetaData(IdentityInstance.KEY, identityModel);
Widget:
IModel<Identity> identity = getRequestCycle().getMetaData(IdentityInstance.KEY);
But the model in Widget is always null. While debugging i found that object
identity is used in Class#equals(Object o), what is ok for me.
But with different classloaders class is loaded multiple times.
I could provide a quickstart for this & create an issue, if you like. (?)
I would like to adapt my configuration so that devtools are still available.
(DCEVM i need to inspect :-).)
Thanks for your support.
Regards
Per
