Viewing page crashes if Content Workflow involved a user who has subsequently been deleted

Running mojoPortal 2.6.0.0 on MSSQL

ContentWorkflow references a user who has subsequently been deleted. A row in mp_ContentWorkflow has a userguid that dien't exist in mp_Users. The page cannot be loaded, with this in System Log:

Re: Viewing page crashes if Content Workflow involved a user who has subsequently been deleted

Hi Crispin,

I've run into this before and found a work-around. I think setting the workflow dropdown from "Work in Progress" to "Live Content" on another page, then browsing to the page will allow you to see it and click the edit link on the content with a draft.

Another solution would be to replace the userguid on the draft content with an existing userguid.

I will take a look at our source code to see if we've fixed this yet, and if not, I'll fix it.

Thanks,
Joe
