Summary	14575: Deleting a parent Survey Group orphans child Survey Groups, causing Survey Groups List page to crash
Description	I would expect that, when a parent Survey Group is deleted, and child Survey Groups would have their parent reset to default. This does not appear to happen.
Steps To Reproduce	Create a Survey Group "test_parent". Create a Survey Group "test_child" and set its parent to "test_parent". Delete "test_parent". Orphaned "test_child" causes "Survey groups list" page to crash with error, "trying to get property of non-object".
Tags	No tags attached.

~~dominikvitt~~ 2019-03-01 11:26 developer ~50722	This issue is resolved. https://github.com/LimeSurvey/LimeSurvey/commit/c75a6610ed6112365e842a1f060959a568440a6b Check is implemented to see if any dependant groups exists, if exists - deletion is blocked and error message is displayed.
