When adding a clear view method you cannot save the rule as the rule designer goes blank after clicking "ok". This resulted in being unable to close the window. Similar behaviour occurred when trying to use the "transfer data" method to empty the fields on the view.
Symptoms would display as the rule designer in K2 designer going completely blank with no functionality after adding rules.
This issue was caused by a script error. Unblocking an Ajax call resolved the problem.
