Breaks on CityObject without geometry

[balazsdukai]

From CityJSON v1.1 the geometry property is not mandatory anymore for CityObjects. If this is the case, the plugin breaks:

Thanks for reporting this! How do you think this should be better tackled? Create no feature at all, or create on with an empty geometry?

[balazsdukai]

If qgis allows empty geometries I think it would be good to create features with an empty geometry. That is in case the CO has attributes, they'll be added to the feature.

[liberostelios]

I decided to go with the latter option (load with empty geometries). There is only a issue, for now, that if you split features per LoD then all features without a geometry will be excluded (as there is no LoD to load these features at).

Nevertheless, this is now fixed and the fix is included in the latest release.

You can install it here or wait for the new version to be approved in the repository soon and upgrade from within QGIS plugin manager.

Thanks for reporting this again! 🙌
