unable to cast object of type Design.VariableDesigner to type Design.DtsBaseDesigner

Nov 2, 2016 at 6:36 AM
hi, I have VS2015 and VS2013 installed and bids helper 1.7.0 (and the latest version of SSMS). Since a week of two I have this problem in VS2013 when trying to change a variable.
The problem is not always there. Yesterday I did a restart and I could change the variables and run the package (hurray!) but this morning it was there again. I can't pinpoint.
The abbreviated error stack:
GetVariableForRow(Int32 iRow)
GetSelectedVariables()
SetButtonEnabled()
grid_SelectionChanged(Object sender, SelectionChangedEventArgs args)

Does anyone have an idea?

thanks, Leon
