Musachy Barroso commented on WW-2654:
-------------------------------------
You can ask about this on the user list, but just a heads up, when you "add" an
interceptor, you also need to add the "params" interceptor, or an stack that
includes it, otherwise the params won't be set on your action.
> Intercept form action, data get lost.

> Key: WW-2654
> URL: https://issues.apache.org/struts/browse/WW-2654
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.0.11.1
> Environment: Tomcat 5.5, Eclipse 3.2
> Reporter: benny lau
>
> Case 1:
> I created a simple login page with username and password textfield.
> when the submit button is clicked, the action will retrieve the field data
> and print it out.
> The above scenario is working fine.
> Case 2:
> added an interceptor
> "org.apache.struts2.interceptor.ServletConfigInterceptor" to retrieve
> servletrequest object.
> when the button clicked, the action retrieve the field data always "empty
> string".
> Case 3:
> Added a custom interceptor implemented interceptor interface. the
> "intercept" method return ActionInvocation.invoke() only.
> when the button clicked, the field data still always "empty string".
> I suspect the intercept function will reset the field data.
