modify the behaviour of the preview button

System

I need to modify the behaviour of the preview button in the template to call a "custom preview module" for some branches.

I saw in TS 5.5.2, this was done in /iw-home/httpd/webapps/webdesk/templating/datacapture_buttonframe.jsp

I am trying to do the same in TS 6.1, i did modify /iw-home/httpd/webapps/content_center/formspub/datacapture_buttonframe.jsp, but I don't see my modifs (I did add an alert in the code) :

else if(buttonClicked.indexOf("preview") != -1) {
alert('preview button clicked');
doPreview();
}

I even tried to delete the content of the whole file, but Teamsite continues to show me the "Select a presentation template popup" !
So I guess i'm not modifying the good file (my knowledge of java is weak).


Anyone can help ?
