[opencms-dev] Downloading a file from Admin interface - A_CmsListDialog

[Michael Moossen]

Hi Chuck!

yes, some how that is not so easy to implement, but we have similar 
functionality in the 'Workplace Tools > Log File' as well as in the 
'Account Management > Im-/Export User Data' tools.
so just check the source code as example.
