[OpenLayers-Users] VectorLayer disappears at zoom 17 (and lesser).

[Erik Uzureau]

Hello BrainDrain, Thank you for verifying the functionality of this feature.
Andreas put the fix in this morning and I have brought it up to the branch
just now, so yes it will be part of the 2.7 release. You can test the
2.7 rc2 here:

thanks for your help!
