Issue in AllItems.aspx when deploying twice

Jun 9, 2008 at 3:41 PM
I'm using this tool to update a site collection I created and I'm experiencing the next issue:

-I'm customizing the lists default view (AllItems.aspx) by adding a custom webpart I've created. So, the version in production doesn't have this webpart and I'm going to deploy the new version of AllItems.aspx with the new webpart.

The first time I deploy these forms there're no problems in the pages and everything is working fine, but the second time I deploy it, I cannot open the page and I receive an error like this: "Already exists the same Id in this page". I cannot open it with Sharepoint Designer.
