Bug
What is the current behavior?
In the "Documents" editor, when you call API method for removing text, the text is removed completely, i.e. without creating a tracked change. Whereas adding text via API in review mode creates a tracked chage.
If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
var oDocument = Api.GetDocument();
var oParagraph, oRun;
oParagraph = oDocument.GetElement(0);
oParagraph.RemoveAllElements();
The title text is removed completely.
What is the expected behavior?
The tracked change is created for the removed title.
Did this work in previous versions of DocumentServer?
Not checked.
DocumentServer version: 5.2.4
Operating System: Windows 10
Browser version: Google Chrome | 71.0.3578.98聽(64聽bit)聽(cohort: Stable)
Notes: the attached image shows the expected result of deleting text programmatically. This can only be achived with manual deleting a title. Deleting it via API edits the document which shouldn't be possible in review mode.
