Getting an error when trying to delete nodes from diagram when added through tool

[Robert Williamson]

Hi guys

I'm using the line tool to create a node if there is no target node. What i've noticed is that when we use this to add a node if we try to delete the node from the diagram we get an error to say "Cannot read property 'segments' of undefined"

Please find an example in the zip at the following URL

Hi Robert, 

 

The reported issue is an sample level issue. Please remove the highlighted line from linktool mousup in your sample to resolve your issue. Please refer to the code example below. 

 

Code example: 

 

class LinkTool extends ej.datavisualization.Diagram.OrthogonalLineTool { 

mouseup(evt) { 

 . . .  

. . . . 

. . . . 

  // this.diagram._updateEdges(this); 

. . .  

. . .  

}; 

};

Hi Shyam

Thanks for this i'm able to delete the nodes now. Just out of curiosity what does the _updateEdges do? 

Thanks

Hi Robert, 

 

The _updateEdges method is used to update the incoming/outgoing connections of the node. We have used this method internally in our source to update the connection. So it’s not necessary to call this method in the application level.

Hi Robert, 

Could you please confirm us whether you need to establish the connection with the ports. If yes, render the ports for the node initially and when you click on the connector tools, the ports will be visible and then you can establish the connection with the ports. Please refer to the sample below for your reference.
