----------------------------------
Summary: 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).
