> (ActionContext.getContext() is null)
> -------------------------------------------------------------------------------------------------
>
> Key: WW-3161
> URL: https://issues.apache.org/struts/browse/WW-3161
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Affects Versions: 2.1.6
> Reporter: Gustavo De Sanctis
> Fix For: 2.1.8
>
>
> I have a simple action that extends ActionSupport and uses the execAndWait
> interceptor.
> In the "execute" method there is a getText("samekey") that fails with:
> java.lang.NullPointerException
>
> com.opensymphony.xwork2.util.LocalizedTextUtil.findText(LocalizedTextUtil.java:318)
>
> com.opensymphony.xwork2.TextProviderSupport.getText(TextProviderSupport.java:191)
>
> com.opensymphony.xwork2.TextProviderSupport.getText(TextProviderSupport.java:106)
> com.opensymphony.xwork2.ActionSupport.getText(ActionSupport.java:80)
> it.test.SimpleAction.execute(SimpleAction.java:10)
> When using the default interceptor stack, it works fine.
> My guess is that as the action context is threadlocal and as the execAndWait
> interceptor creates a new thread to handle the request... this new thread has
> no reference to the action context (infact ActionContext.getContext() returns
> null when using execAndWait)
> Below the data to reproduce the problem:
> *****************************
> ACTION CLASS: it.test.SimpleAction
> *****************************
> package it.test;
> import com.opensymphony.xwork2.ActionContext;
> import com.opensymphony.xwork2.ActionSupport;
> public class SimpleAction extends ActionSupport {
> public String execute(){
> System.out.println(ActionContext.getContext());
> addActionMessage(getText("message.sample","ciao"));
> return SUCCESS;
> }
> }
> ***********************
> Struts config
> ************************
> <action name="simple" class="it.test.SimpleAction">
> <interceptor-ref name="execAndWait" />
> <result name="success">/simple.jsp</result>
> </action>
> ***********************
> simple.jsp
