I have QGIS 2.14.
I opened a .shp file (with dbf etc) and selected a few features. Created a new QGIS project and pasted features as new Vector Layer.
The attributes table was created automatically in correct schema (field names & types) however the values are NULL.
I have explored other questions on stackexchange but they seem to be focusing on schema or field definition problem, in my case the schema is exactly same but still NULL values appearing.
Any ideas ?
