Portlet Loading error because cant't find app descriptor
--------------------------------------------------------
Key: PLUTO-502
URL: https://issues.apache.org/jira/browse/PLUTO-502
Project: Pluto
Issue Type: Bug
Components: portlet container
Affects Versions: 2.0.0
Environment: Tomcat 5.5
Reporter: Gonzalo Aguilar
Hi All!
Pluto container does not find testsuite portlet.
At first I thought that was something related with deployment configuration. So
I made some detailed log and found that a problem with the crossContext=true
switch was found in the tomcat server configuration file.
Now it seems it does not find the portlet application descriptor. Here is the
error (looks little bit modified to be able to trace without all stacktrace
logging):

But two questions arise:
Why it tries to get the portlet application descriptor 3 times (one for each
portlet view mode)? The first one failed, the rest should also fail.
When this portlet must be initialized. I suppose that the first time we go to
see the page... What class is reponsible of this?
Because the portlet application descriptor is not in the context.
Thank you very much!
