No, I don't.
I don't see why Wicket should be responsible for the way other libraries
work.
If you create a quickstart that does not use any third party libraries then
we will take a look!

Aw: Re: Wicket Spring boot - use spring devtools
Hello Martin,
the problem is that i assign a model in request cycle metadata by using the key
public class IdentityInstance extends MetaDataKey> {
public static IdentityInstance KEY = new IdentityInstance();
private IdentityInstance() {
super();
}
}
Page:
getRequestCycle().setMetaData(IdentityInstance.KEY, identityModel);
Widget:
IModel 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.

Re: Wicket Spring boot - use spring devtools
Hi, This is how Spring Dev Tools work. When it detects a change it removes the old application class loader and creates a new one. Why this is a problem for you ? I personally prefer to use DCEVM (https://dcevm.github.io/). It is able to redefine a specific class in the current class loader. When I change a Spring @Configuration or Hibernate mapping I just restart the application manually.
