I have a custom feature that, when activated, alters a document library (adds content types, sets up views, attaches a workflow). For some reason, the first time I activate the feature nothing seems to happen. The page refreshes but the feature still shows as deactivated.

When I look at the document library I can see some of the changes have been made, but not all. When I activate the feature a second time the page correctly refreshes and shows the feature to be active - verified by looking at the document library which contains all changes.

There's nothing I can see in the ULS logs to tell me what happens the first time I try to activate, I've got no idea how I can debug this issue as attaching to the process and stepping through the code isn't an option.

Any ideas?

If code is running too long the asp.net feature activation could be terminated. Try to edit web.config in 14 hive

< location path="_layouts/ManageFeatures.aspx" > < system.web > < httpRuntime executionTimeout="3600" / > < /system.web> < /location > I just set the time for one hour it's should be enough.
