ClassCastException in PipelineEditor

[dcram]

There are two ClassCastException when the pipeline editor open. This has appeared after migration to Eclipse 4.6.

This seems to be due to a bad UpdateValueStrategy on text fields for filter threshold and topN values.

java.lang.ClassCastException: java.lang.Double cannot be cast to java.lang.String
