> In our current project we are upgrading struts 2.3.35 to 2.5.22 and we encounter some minor bug in below code of addParametersToContext method of StaticParametersInterceptor.
> in method, code is like below.
>
> {code:java}
> if (overwrite) {
> if (previousParams != null) {
> combinedParams = combinedParams.withParent(previousParams);
> }
> if (newParams != null) {
> combinedParams = combinedParams.withExtraParams(newParams);
> }
> } else {
> if (newParams != null) {
> combinedParams = combinedParams.withExtraParams(newParams);
> }
> if (previousParams != null) {
> combinedParams = combinedParams.withParent(previousParams);
> }
> }
> {code}
>
> But here overwrite functionality will not work since only if condition order was changed in else condition of overwrite.
> instead of this, as per me, code would be like below
> {code:java}
> if (overwrite) {
> if (previousParams != null) {
> combinedParams = combinedParams.withParent(previousParams);
> }
> if (newParams != null) {
> combinedParams = combinedParams.withExtraParams(newParams);
> }
> } else {
> if (newParams != null) {
> HttpParameters newHttpParameters = HttpParameters.create(newParams).build();
> combinedParams = combinedParams.withParent(newParams);
> }
> if (previousParams != null) {
> combinedParams = combinedParams.withExtraParams(previousParams);
> }
> }
> {code}
>
> And that's how ac.setParameters(combinedParams.build()); will work because in build method, requestParameterMap will override parent parameters.
