I have the following class: class VirtualFile(Tabs, Implicit): "Wrapper around a file on the filesystem." [snip] manage_options = (({'label' : 'Info', 'action' : 'manage_main'}, {'label' : 'View/Download', 'action' : ''}, )) [snip] Let's suppose, I'm in zmi and access the management screen of an instance of this class via the following url: http://127.0.0.1:8002/Instances/tempo/ExternalFolder/EFExceptions.py/man age_main The link for the first management tab is just fine (href="manage_main"), but the second one (View/Download) is wrong, it's: href="http://127.0.0.1:8002/Instances/tempo/ExternalFolder". If I change the action field of 'View/Download' to 'index_html', the generated url will be okay again: href="index_html". What should I write in the action field to provide "http://127.0.0.1:8002/Instances/tempo/ExternalFolder/EFExceptions.py" as the url? Regards, Sandor
