Thanks Willr, I'll leave it for now then. Looking forward to the beta (even though that'll be quite some time yet I'd imagine).
The alpha release states there will be a beta before end of 2011 with stable first quarter 2012. Assuming that the current build on github is actually current, I don't see how.
I gave up, and made a LOT of progress in SS 2.5.x, I love the new NestedDataObjectManager stuff!
Hi all... just read this quickly trying to find the answer... figured my issue out with beta 3 using something like:
Page has_many Brands
$brandsConfig = new GridFieldConfig_RelationEditor(); // is pre-defined GridFieldConfig
$brandsTable = new GridField("Brands","Brands",$this->Brands(),$brandsConfig);
Hope this helps someone
