Subversion svn:externals - What's wrong here?

I first want to say I've read the Subversion manual. I've read this question. I've also read this question. Here's my dilemma.

Let's say I have 3 repositories laid out like this:

• DataAccessObject/
  • branches/
  • tags/
  • trunk/
    • DataAccessObject/
    • DataAccessObjectTests/
• PlanObject/
  • branches/
  • tags/
  • trunk/
    • PlanObject/
    • PlanObjectTests/
• WinFormsPlanViewer/
  • branches/
  • tags/
  • trunk/
    • WinFormsPlanViewer/

The PlanObject and DataAccessObject repositories contain shared projects. They are used by the WinFormsPlanViewer, but also by several other projects in several other repositories.

Bear with me here. I put an svn:externals definition on the WinFormsPlanViewer/trunk folder like this:

https://server/svn/PlanObject/trunk Objects<br/>
https://server/svn/DataAccessObject/trunk Objects<br/>

And here's what I see after I do an svn update.

• WinFormsPlanViewer/
  • branches/
  • tags/
  • trunk/
    • WinFormsPlanViewer/
    • Objects/
      • DataAccessObject/
      • DataAccessObjectTests/

The PlanObject stuff doesn't even come down in the update! I don't know if this has anything to do with it, but there's an externals definition on the PlanObject/trunk folder also:

https://server/svn/DataAccessObject/trunk Objects<br/>

What's going on here? What am I doing wrong? Are there bad consequences of referencing the PlanObject and the DataAccessObject from the WinFormsPlanViewer using svn:externals when the PlanObject references the DataAccessObject using svn:externals also?

You have configured the svn:externals property to populate the Objects directory with the contents of two different URLs. Try creating the two svn:externals with different directory names:

https://server/svn/PlanObject/trunk PlanObjects
https://server/svn/DataAccessObject/trunk DataAccessObjects
