IE vs firefox

[pedrosacosta]

I've build an aplication that works in jboss portal. I acess the application with this url:

http://localhost:8080/portal/auth/portal/BEM-Portal/Acidentes

The problem is that, in the firefox browser, when i submit an event, the page jumps to the current url. But in Internet Explorer, the page goes to
http://localhost:8080/portal/auth/portal/BEM-Portal/, which is incorrect.

Has anyone have problems regarding the browser?

How can i solve my problem?

Here is the URL of my page, obtained from the browser:

<form name="listForm" method="post" action="/portal/auth/index.html?ctrl:cmd=action&ctrl:mode=view&ctrl:window=BEM-Portal.Acidentes.EventsListPortletWindow&action=view">

Here is the real line in the jsp file:

<c:set var="addRowURL">
 <portlet:actionURL portletMode="view">
 <portlet:param name="action" value="view"/>
 </portlet:actionURL>
</c:set>
.
.
.
<form name="listForm" method="post" action="${addRowURL}">
</form>

Thanks,
Pedro
