Subject [jira] [Created] (WW-4526) Invalid action generated by the form tag
Date Tue, 14 Jul 2015 14:21:04 GMT
Vanacker David created WW-4526:

             Summary: Invalid action generated by the form tag
                 Key: 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 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).
