Forum OpenACS Development: Re: while creating a new project in ]project-open[...
I don't much about Project Open but you could try asking your question on their forum. However, the error you are seeing looks quite straightforward - you're trying to run a proc called activity::new but you haven't created it first. The 'project::new' refers to a namespace called project which contains a proc called new. So similarly, you will need a namespace called 'activity'.
hope this helps
Could you please send me any official forums for ]Project-Open[ ?
