Questions Generic Inquiry Screenid changes to ScreenId=00000000

After trying 3-4 times, deleting off the sitemap and reentering I had given up. I went back to the Generic Inquiry this morning and voila - the screenid had returned to the URL! 
So strange. If it happens again, I will definitely report this to Acumatica. 

Thanks for the input, everyone! Much appreciated!

Is it possible it is somewhere else on the Sitemap? I have never experienced this problem before.

Perhaps read through the XML of the GI and look for anything unusual. 

Good idea Royce.

Hazen, you could create a GI that looks at the SiteMap table to see, when it happens again, if the Screen ID is used in multiple places.

You get a Warning if you create a Site Map entry that uses the same Screen ID multiple times, but not an Error. 

I'm not sure why it's not an Error to prevent it from happening. I created a suggestion to make it an Error instead of a Warning:
