TypeError: Cannot read property '$$hashKey' of undefined Issue When using the service portal widget 'Data Table from URL Definition' the results are not displayed and in the browser console the following error is presented:

TypeError: Cannot read property '$$hashKey' of undefined

Cause The widget 'Data Table from URL Definition' has a dependency to another widget 'Data Table'

and

'Data Table from URL Definition' /sp_widget.do?sys_id=8ae61f55cb21020000f8d856634c9c93
