Lukasz Lenart commented on WW-4066:
-----------------------------------
The problem isn't related to {{ModelDriven}} but to order of interceptors in
{{paramsPrepareParamsStack}} and the mentioned warning is just in {{devMode}}
to alert developer that something potentially can be wrong.
If you take a look on {{paramsPrepareParamsStack}} you will spot that the
{{params}} interceptor is listed two times - before and after {{prepare}}, but
there is also {{modelDriven}} listed just before the second {{params}} which
will put non-null {{Model}} onto stack.
The mentioned warnings come from the first {{params}} as action doesn't have
appropriate setters and {{Model}} wasn't yet put onto stack. Even if you add
additional {{modelDriven}} interceptor before the first {{params}}, model still
won't be on the stack as it is null. That's why I have suggested to create a
dedicated interceptor to solve that uncommon situation or move logic to create
{{Model}} into {{getModel()}} method.
Or leave everything as is as it's just a warning in {{devMode}} ;-)

> Our BaseAction which extends ActionSupport overrides the addActionMessage()
> with the following:
> {code:java}
> @Override
> public void addActionMessage(String message) {
> super.addActionMessage(getText(message));
> }
> {code}
> With the above method in place during devMode=true, the following error stack
> trace occurs:
> {noformat}
