Installing portlet has broken control panel

[Matt Hunter, modificado 15 Anos atrás.]

I've just recently started looking at Liferay - and we're expecting to use it to replace our current aging portal.

Yesterday I installed a fresh copy of 5.2. Just to see how hard it would be to move one of our portlets to Liferay, I used the control panel to upload the portlet .war file and install. It reported success, so I went to the Plugins Configuration page to look at it. Now, however, that page (Plugins Configuration) just loads a blank page. I Tomcat's log files, I see:

15:12:22,718 ERROR [PortletContextFactory:86] Portlet RssPortlet_WAR_SRssPortlet has a null portlet bag

...

While I completely understand that there may be a bug in the portlet that will need mending to make it work with liferay, I don't understand how liferay is allowing one malfunctioning portlet to completely kill the plugin management pages. How do I go about removing it now? Is this - a simple portlet error crashing parts of the portal - a known issue?

Thanks,
Matt
