Gabriel Belingueres commented on WW-2595: ----------------------------------------- I would recommend that you post the *real* struts.xml section that reproduces the problem. Regards, Gabriel > Overriding subset of interceptor params > --------------------------------------- > > Key: WW-2595 > URL: https://issues.apache.org/struts/browse/WW-2595 > Project: Struts 2 > Issue Type: Bug > Affects Versions: 2.0.11 > Reporter: Jon Wilmoth > > Trying to override one of three interceptor parameters in an action specific > config using method #2 described in > http://struts.apache.org/2.0.11.1/docs/interceptors.html#Interceptors-InterceptorParameterOverriding > leaves the params that aren't overridden in the action (but defined in stack > definition) null. Unfortunately, the other two parameters that I'm not > overriding are not being taken from the default stack definition and are > ending up as null on the interceptor. Below is a sample action config > showing what I'm attempting... > <package name="packageA"...> > <interceptors> > <interceptor name="myInterceptor" class="..."/> > <interceptor-stack name="myStack"> > <interceptor-ref name="defaultStack"/> > <interceptor-ref name="myInterceptor"> > <param name="paramA">defaultValueA</param> > <param name="paramB">defaultValueB</param> > <param name="paramC">defaultValueC</param> > </interceptor-ref> > </interceptor-stack> > </package> > With the following action config, the "myInterceptor" interceptor's paramA & > paramB are null (causing the interceptor logic to break) and not > "defaultValueA" and "defaultValueB" as expected/desired. > <package name="packageB" extends="packageA"...> > <action name="myAction" class="myActionClass"> > <interceptor-ref name="myStack"> > <param name="myInterceptor.paramC">actionSpecificValue</param> > </interceptor-ref> > </action> > </package> > BTW...defining the action with all parameters overridden (see below) works: > <action name="myAction" class="myActionClass"> > <interceptor-ref name="myStack"> > <!-- same value as defined in "myStack" declaration --> > <param name="myInterceptor.paramA">defaultValueA</param> > <!-- same value as defined in "myStack" declaration --> > <param name="myInterceptor.paramB">defaultValueB</param> > <param name="myInterceptor.paramC">actionSpecificValue</param> > </interceptor-ref> > </action> -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
