-----------------------------------
How WW-3760 broke this?

> staticParams interceptor overwrites params conversion errors
> ------------------------------------------------------------
>
> Key: WW-4288
> URL: https://issues.apache.org/jira/browse/WW-4288
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Affects Versions: 2.3.15.3
> Reporter: Jasper Rosenberg
> Fix For: 2.3.x
>
>
> Have a stack like:
> ...
> <interceptor-ref name="params">
> <interceptor-ref name="staticParams"/>
> ...
> <interceptor-ref name="conversionError"/>
> If have type conversion errors in params, they aren't seen by the conversionError interceptor.
> It looks like this in StaticParametersInterceptor:
> {code:java}
> if (clearableStack && (stack.getContext() != null) &&
(newStack.getContext() != null))
> stack.getContext().put(ActionContext.CONVERSION_ERRORS, newStack.getContext().get(ActionContext.CONVERSION_ERRORS));
> {code}
> ends up just overwriting the old value of ActionContext.CONVERSION_ERRORS rather than
merging.
