Welcome to the wonderful world of third-party frameworks:)

No. You can use a WOComponent, take a look at the BugTracker.HomePage. 
The ERDCustomComponent is a base for components that should be used 
both with and without D2W.

This is probably because xcode can't find the model file. Do you get a 
message in that regard?

Can't tell w/o more info.

editRelationshipConfigurationName (or editRelationshipPageConfiguration 
in a Wonder version older than two weeks) must return the value for a 
valid EditRelationshipInterface. Try to add a string in 
ERD2WEditToManyFault with d2wContext.xxx and see what it puts out?

Probably a bug. I don't use sorting in related views anyway, just set 
the defaultSortOrder to the field most likely to sort on.

The D2WModel.defaultModel() should be a ERD2WModel.
