I'm getting a curious error when attempting to generate a view via the 'Add View' dialog. Simply leaving the dialog as is (ie creating view 'View') and hitting 'Add' yields the following error dialog:
Error: There was an error running the selected code generator: 'The Templates/PackageVersions5.0.1xml file is missing from the installed template folder.'
I'm afraid the rather unsatisfactory solution I arrived at was to create a clean project and import the project elements in, recreating the project from scratch.
I assume that some deep-configuration had become corrupted and I was unable to work out how to fix it.
