I am using Slicer version 4.3.1 on ubuntu 16.04. I am getting the error  
qMRMLSliceWidget has no attribute named ‘imageData’

Does any know why this is happening?

[qMRMLSliceWidget](http://apidocs.slicer.org/master/classqMRMLSliceWidget.html#a9d165dee031dfbb2105108871173482b) has `imageDataConnection` method instead.
