Unable to add selected webpart(s) [closed]

Question

I've created a Custom List ('Tooltips') in SharePoint. After this I used SPSource to reverse engineer the list into a feature.

After installing and activating this feature, I want to add this list in a WebPart zone.

When doing this, I get an error message :

Tooltips: List View Web Part could not be added, list may be hidden.

What's wrong with the list?

feature.xml

<?xml version="1.0" encoding="utf-8"?>

Answer 1

Order of operations? Are you trying to add it to the zone before the list was created?

Answer 2

I would check logs and safe control entry in web config file. For debugging SP issues check http://blog.thekid.me.uk/archive/2007/07/25/debugging-tips-for-sharepoint-and-wss-exceptions.aspx
