When I call a popup fucntion in the onclick attribute
from the html link tag.
I see a blank page.

here is my code :
<html:link page="" onclick="popup('<%=editUrl%>')"><bean:write name="articleView" property="titre"/></html:link>

below the editUrl scriplet

<bean:define id="code" name="articleView" property="codeArticle" type="java.lang.String"/> 
                        <%
                        String 
editUrl="/editArticle.do?codeArticle="+code;
                        %>

the popup function just open a popup.

Can someone explain me why editUrl is not called .
