Thank you @jerosoler, these links gave me idea to prevent deletion of particular node. The solutions provided on #10 and #70 gave me some direction to implement my own problem area.
Hello @jerosoler ,
With your solution, it was great help for me to handle to do something like confirmation before delete .
But, now I am facing a new issue with above. Above solution was working perfectly fine when there was no connection between two nodes. When there is connection between two nodes, and I try to remove one node, node remove successfully, but not the connection arrow. I want to remove connection also when node is deleted, and when I look on console of browser console tool, then following error is displayed sometimes for output and sometimes for input node:
Uncaught TypeError: Cannot read property 'inputs' of undefined
at Drawflowoverride.removeConnectionNodeId (drawflow.min.js:1)
at Drawflowoverride.removeNodeId (drawflow-custom.js:19)
at Drawflowoverride.click (drawflow.min.js:1)
removeConnectionNodeId @ drawflow.min.js:1
removeNodeId @ drawflow-custom.js:19
click @ drawflow.min.js:1
Uncaught TypeError: Cannot read property 'outputs' of undefined
at Drawflowoverride.removeConnectionNodeId (drawflow.min.js:1)
at Drawflowoverride.removeNodeId (drawflow-custom.js:19)
at Drawflowoverride.click (drawflow.min.js:1)
removeConnectionNodeId @ drawflow.min.js:1
removeNodeId @ drawflow-custom.js:19
click @ drawflow.min.js:1
Hello @jerosoler ,
Issue is resolved as I moved the line
this.removeConnectionNodeId(id);
at start of function
class Drawflowoverride extends Drawflow {
removeNodeId(id) {
instead at last line.
Whether there is any option or setting to disable deletion of node? Currently, deletion is possible with delete button and cross icon shown when the node is selected. Both options need to be stopped for a particular node.
