When there are errors on your work items it's not clear on which line the error is

[Guilherme Salgado]

When there's an error in the work items entered by the user we display an error explaining what's wrong (e.g. invalid status/assignee/milestone) so that the user can fix them. However, there's no indication of the line where the error occurs so on a long list of work items (which is very common) it becomes slightly annoying to find out the one that has the error.
