I have faced with strange flaw of MS CRM 2011 deployment process.
Developer is able to deactivate views on development system, however it's impossible to transfer this customization to the target system via solution. Here is relevant blog post about this issue, "View Status" topic.
But maybe this operation is possible to perform via direct XML editing?
Otherwise if solution is managed, it's impossible to modify view's status on target system... Is there any way around this issue?
