[opencms-dev] OpenCMS: 404-error-handling

[Bernd Wolfsegger]

Thanx for this information Alex.
Just thought about the 500 because it is in the Handler_Names.
But you're right there need to be a 500 entry in the web.xml.

As for the exception information, I will test a little bit.

By the way, the OpenCms explorer navigation hang bug I posted some time ago 
seems to be gone with the beta 2. :)
But if I have selected "/" site in the explorer view and have the "/sites" 
tree unfolded for editing some resource and than unfold the "/system" tree 
too and open some resource below and close or save it again, the "/sites" 
tree is displayed folded again after that, and vis versa.
If you jump back and force between both while developing site content 
templates and site layout templates its a little bit annoying.

Kind regards, Bernd
