[Bug 654030] Re: NullPointerException on importing CSV data in Data Laboratory

 

Hi Axel, importing dynamic attributes from CSV works fine if the dynamic column is already created and dynamic.
So to import CSV data with dynamic weights for edges in a existing project the Weight column has to be dynamic float and can't be float. The edges are keeping the value 1 because the weight column is float and can't have a dynamic value.
