Struts2, have to eneter site twice to get the list populated

Hello!

I have the following problem, I am using struts2 and hibenrate 3.0.
1. I click for the first time on menu postion that calls web page with a list with all users i get empty result( despite the fact there should be something)
I see in debug mode that it goes to execute() but not to getUsersList()
2. I have to go back in browser
3. Click one more time: It works, (goes to both: execute() and getUsersList())

Is there any parameters in beans/struts/xml that tells the web page not to try to wait for result from getter with elements for the list?

Thanks for try, but it helped me partly:
Good: It goes straight to getUsersList()
Bad:
It gives me
java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.String
So i think struts tries to match the result from getUsersList(), which is ArrayList,
to string (possible results in struts.xml for action ViewUsersListAction)...

Waiting for any ideas...

I ve changed the execute() in ViewUsersListAction class to:

public String execute() {
System.out.println("ViewUsersList execute!");
getUsersList(); //new line!!!
return SUCCESS;
}

And it accured that it display-tag is faster than function getUsersList() gives the result...
I found also simmilar problem:
