VirtualPathUtility.ToAppRelative NULL reference exception


In file: Orchard\DisplayManagement\Descriptors\ShapePlacementStrategy\ShapePlacementParsingStrategy.cs

Line: 142

VirtualPathUtility.ToAppRelative(ctx.Path ?? "")

VirtualPathUtility.ToAppRelative("") will throw a parameter null exception... I know its not null but but a empty string "" is not valid. hence the ?? "" is irrelevant

Not sure how the code should work but it could be changed to: VirtualPathUtility.ToAppRelative(ctx.Path ?? "/")

The suggested change seems to work for me.

Related issue: https://orchard.codeplex.com/workitem/18891 (which has been marked as fixed, but does not fix my issue)

My scenario: I have the following placement entry in my module:
<Match Path="~/LETS/Notice/*">
  <Place Parts_Title_Edit="Content:0"/>
Since upgrading to V1.6 (from 1.4) I'm getting empty titles on all content types & paths; they are not set because of the null reference thrown as above.

By reversing the fix in issue 18891 and applying this change (the slash), the titles now work properly.
