Automerge branch to trunk fails - Sparse Checkouts not supported?

[Charles Wilt]

I've had a branch open for a couple weeks...

Periodically have done sync merges trunk --> branch using the right-click "merge all"

Yesterday, I did my final sync merge and then tried to merge my branch back to the trunk...

It failed with the following:

Command: Auto-merge https://dmssjosvn01.dt.inc:8443/svn/DMS/DevTrunk/FO4924 into C:\SVN\DevTrunk\Dev  

Error: Reintegrate can only be used if revisions 36032 through 36478 were previously  

Error:  merged from https://dmssjosvn01.dt.inc:8443/svn/DMS/DevTrunk/Dev to the  

Error:  reintegrate source, but this is not the case:  

Error:   DevTrunk/FO4924  

Error:     Missing ranges:  

Error:  /DevTrunk/Dev:36056,36072,36075,36079,36089,36115,36125,36144,36169,36182,36198-36199,36216,36218,36221,36230,36233-36234,36243,36252,36299,36326,36341,36358,36373,36392,36396,36398,36410,36431  

<lots more snipped>

I thought I'd recalled seeing that the auto-reintegrate now supported sparse checkouts...is this not the case?

Or perhaps the silly way we have the repository structured is the problem...

Thanks!
