When I want to delete either a whole page, or an attachment, I get the message :
This template uses in an unsupported context: del
The log shows the following stacktrace (truncated) :

Since I didn't feel very comfortable running JSPWiki in WebSphere (no good support, and it's not really tested in the public), I switched to Tomcat (5.5.17) with container managed security. I wrote a custom Tomcat RACFRealm, so we have integration with the native z/OS security subsystem. However, the problem still occurs when trying to delete a page or attachment. I did some more tests, and it looks like it has something to do with the "automatic" switch from http: to https: when you try to delete a page (due to the security constraint setting in web.xml).
When you first manually display the page over https instead of http, and then hit the Delete button, then you can succesfully delete the page. I haven't had the time yet to further investigate this yet.
