Find data panel does not support search of string values in a vtkStringArray
Find data panel does not support search of string values in a vtkStringArray. This is not possible because a vtkStringArray cannot be mapped to a NumPy array which is used by the python selector, which is then used by the Find Data Panel. This mapping cannot be performed (as of now) because a vtkStringArray is a special array where the memory size of each value is dynamic.
