Vanacker David updated WW-4526:
-------------------------------
Attachment: (was: struts2-form-url.zip)
> Invalid action generated by the form tag
> ----------------------------------------
>
> Key: WW-4526
> URL: https://issues.apache.org/jira/browse/WW-4526
> Project: Struts 2
> Issue Type: Bug
> Components: Core Actions, Value Stack
> Affects Versions: 2.3.24
> Reporter: Vanacker David
> Priority: Critical
>
> Following the migration of Struts framework from 2.3.16.3 to 2.3.24, we
> detected that the action attribute of HTML tag Form generated with the Struts
> Form Tag contains an invalid scheme when the associated action class contains
> an accessor named getScheme().
> The value of this accessor is retrieved in
> org.apache.struts2.components.ServletUrlRender#renderFormUrl() from the
> ValueStack.
> ValueStack vs = ActionContext.getContext().getValueStack();
> String scheme = vs.findString("scheme");
> The attachement contains a sample that illustrate the issue.
> Run simply the command mvn tomcat:run to execute it .
> It contains also a "patch" that overrides de DefaultUrlHelper . It checks if
> the scheme is equals to a valid scheme (http/https) and calls the default
> implementation. In case of the scheme is not valid, it calls the default
> implementation with null argument for the scheme ( replaced by the
> HttpServletRequest#getScheme() in the default implementation).
