Can't make a portlet work with the eclipse plugin

[philippe aristote <philippe.aristote@xxxxxxxxxxxx>]

Hi,

i've made a portlet using the eclipse plugin (new > Portlet > ...) but, 
as i'm deploying it on a remote server, i'm using an ant task. in exo, 
my portlet is well recognized but generates an exception :


EXO-ERROR: Portlet container throw an exception null 
java.lang.String.(String.java:166) 
org.exoplatform.portal.faces.renderer.html.portlet.PortletRenderer.encodeChildren(PortletRenderer.java:102)
...


i checked the portlet.xml and web.xml files but they are the same as 
other portlets that works...so i don't know where this exception comes from.

if someone does, thanks for helping me !

phil.
