I was using the previous DXA version where it was possible to use empty regions
<tri:entities region="HeaderRegion"/>
Doing a migration to 1.4, we just changed the tag to:
<dxa:entities region="HeaderRegion"/>
But we realised that this is not working anymore. When we try to render the page we've got the error
Region not found on page: GeneralHeader
How can we have the same behaviour as before?
The dxa:entities Tag is intended to be used in a Region View in order to render all Entities within that Region. You don't specify a Region Name in the tag, because it acts on the current Region.
In DXA 1.2+ the best way to deal with empty Regions is to predefine your (potentially) empty Regions in your Page Template metadata. This will ensure that empty Regions exist in the DXA Page Model and hence they will get rendered with an appropriate Region View even when they are empty.
Alternatively, you can use the dxa:Region tag with a emptyViewName parameter to render a Region with a given name, even if the Region does not exist in the DXA Page Model.
