how to edit the highlighting of fromPort and toPort when creating a link in flow.
I want to highlight the toPort only, if set
diagram.toolManager.linkingTool.temproraryFromPort=null
or
localDig.toolManager.linkingTool.temporaryFromPort = localDig.toolManager.linkingTool.originalFromPort
it shows error message of
go.js:1161 Uncaught TypeError: Cannot read property ‘panel’ of null
at U.push…/…/node_modules/gojs/release/go.js.t.tb
Try setting its opacity to zero.
