Description

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:

if (clearableStack && (stack.getContext() != null) && (newStack.getContext() != null))
    stack.getContext().put(ActionContext.CONVERSION_ERRORS, newStack.getContext().get(ActionContext.CONVERSION_ERRORS));

ends up just overwriting the old value of ActionContext.CONVERSION_ERRORS rather than merging.
