Predecessor setting using UI is not working

[Kuntal Patel]

Hello,

I'm trying to set predecessor using UI (right side of the chart) ,but its not working. Tooltip which gets displayed while clicking on the dot displays error. Looks like one of the file is missing. Please find the attached snapshot which shows the issue when i click the dot at end of the task.

Hi Kuntal, 

We can make the relationship between two tasks from chart side by dragging the connector line from one task to another task.  

Please find our online documentation for different task relationship in Gantt.

We have also attached the demo video about connecting the predecessor line for your reference. Please find the video from below location

I got your point,but i'm not at all able to drag the line. Even in valid case, i get error popup only.
