HI @JCgH4164838Gh792C124B5 @lukaszlenart
Apologies I didn't mention exact scenario that triggered this bug. But now I
have added scenario in JIRA ticket
[WW-5096](https://issues.apache.org/jira/browse/WW-5096) which triggered this
bug.
@JCgH4164838Gh792C124B5
yes, you are correct.original code of StaticParametersInterceptor
addParametersToContext() was doing the same operations irrespective of
overwrite is true or false.

> Project: Struts 2
> Issue Type: Bug
> Reporter: Akash Shah
> Priority: Minor
> Fix For: 2.5.26, 2.6
>
> Time Spent: 50m
> Remaining Estimate: 0h
>
> 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.
