------------------------------------

             Summary: 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


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.
