While mapping dependency from one task to another task is breaking in Gantt chart .Using version of Gantt chart@17.2.34.

Gantt chart also use some part of Diagram(Syncfusion).We are using Diagram@17.1.47.If we upgrade the version of Diagram, Connector is breaking in Diagram .

If we use latest version of everything, then very asynchronous behaviour we are getting .

Can you please suggest us which version we should use that both Gantt chart and Diagram will be working without brake.

Please find attached Screen shot .

Hi Sudhanshu,

Thanks for the contacting.

We have tested reported scenario in our local application with Gantt and Diagram controls in same page. But we can’t reproduce this error, please find the sample we are used for testing in below link. We have ensured this by rendering Gantt inside the IFRAM tag and on model dialog but we can’t get the issue. 

Sample Link – https://www.syncfusion.com/downloads/support/directtrac/general/ze/SimpleGantt-1530811079 

We have drawn the connector line by find the exact position of connector point on mouse down action and updated the connector line position on mouse move action. This issue may occur when we get the improper element position on mouse down event. Please share the following details to us it will helpful for us to check and provide proper solution for this issue. 

Position of Gantt control in web page with screenshot, you can get position by chrome developer tools.
Are you rendering Gantt inside any absolute positioned container element(DIV)?
Ensure duplicate Syncfusion packages in node modules folder.
If can provide the issue reproducible sample.

Please let us know if you have concerns.  

Thanks,

Gurunathan

Hi Sudhanshu,

Thank you for your detailed update. 

We have analyzed the provided video, this looks connector line update action was broken due to some console error, on connector line draw action we are rendering a dotted line, this line will be removed on successful update of predecessor update action. 

Can you please share us the below mentioned details? 

The screenshot of console error.
Share code snippets if any customizations done in actionBegin and actionComplete event.
Issue reproduceable sample or modify our sample which is previously updated by us to provide proper solution.

Thanks, 

Gurunathan
