Lukasz Lenart updated WW-3161:
------------------------------
Description:
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:
{noformat}
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)
{noformat}
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
*****************************
{code:java}
package it.test;
import com.opensymphony.xwork2.ActionContext;

System.out.println(ActionContext.getContext());
addActionMessage(getText("message.sample","ciao"));
return SUCCESS;
}
