New window everytime when submit button clicked in JSF

Question

Hi all,
I am facing an issue where I need to popup a new window everytime the submit button on my JSF form is clicked.
I have tried several methods but none is working to my purpose.
1. Add a target="_blank" attribute in the JSF form. The problem is that even if any of my ValuechangeListeners get invoked, the page is rendered in a new window. My ValuechangeListeners work on onchange="submit()".
2. Invoke a new window from javascript and name the window as say" new" . Also name the form's target as "new" but this does not generate a new window everytime and also problem 1 persists.
3. If i use actionlistener and onclick event on button in the form, then the new page is rendered in both current page and new window.( javascript for new window is written).
What I need is when a person clicks on submit button in the form, a new window should always popup up and the page should be rendered in the new window. The original form should remain as it is so that a user can again do a submit and get a new window.
Please suggest.

Thanks all for the replies.
Try onchange="this.form.target='_self';submit();"This works fine if all the valuechangelisteners are invoked. Suppose,if I dont select the radio
button and dont select any values in list box. Now if i click submit, since the target=_blank,
the page giving validation errors (for not selecting the list box)
renders in a new page. As expected behavior, not my solution.
If you need validation to remain in the same window (and that seems like the best for the user experience you have described), then delay the creation of the new window until after the request finishes. I.e., your page should always go back on itself. Under the right conditions (which you can set in your action method) it conditionally writes JavaScript which targets the new window.

Try returning false from the onclick event.I had tried it long back, so I just messed it up while writing, there were no actionlisteners.
sorry about my third solution, lets consider solution 2 as below:
Javascript
<script type="text/javascript" >
     function newWindow(){
          window.open('','mywindow','width=400,height=200');
          return false;
     </script>
JSF
<h:form id="Frm_New" target="mywindow">     
<h:commandButton id="btn_submit" disabled="false"             
              action = "#{TestBean.submitValues}"
              value="#{bundle.SC_SUBMIT}"
              onclick ="newWindow()">But again this approach has above problems and also no new window everytime. For new window you said:
Append a time stamp or random number to
the end of the window name.This solution will not work as I have to reset the target for my form everytime to this new window name.You can remember the name of the window if necessary. Although you seem to be changing things on the fly; earlier the problem was you didn't get a new window every time. Or are you just confused on how to set the target?
onclick="var wname = getWindowName(); createNewWindow(wname); this.form.target = wname; return true;">
I was trying to actually set the target of the form as _blank at runtime during one of the phases of JSF lifecycle ( by using phaselistener). Although its not working as of now. Does this sound a good approach
This is because I dont think that setting it on jsf would work as the page rendering on a new window( in my case) not only depends on clicking the submit button only but it depends on whether the user is done with all vaildations and now has to see the final result into new window.This would be addressed by the conditional JavaScript solution above.
