red cross shows on the previous location until create a new elevation profile

[chen7012]

Steps to reproduce:
1.click on the measure button
2.click one point, and double click on the map to set the end point for the measure.
3. waiting for the elevation profile to be created, then hover on the profile.
4, the red cross will show on the map.
5. single click on the map again to start the new measure, but the red cross is still showing on the previous location.

Is there a way to clear it?

I resolved the issue by adding a handler for "measure-stat" event. Here is the detail:

1. added the line of code to _initMeasureTool: function () in Widget.js in the templete:

       this.onMeasureStart=this.measureTool.on("measure-start", lang.hitch(this, this._onMeasureStart));
   

2. added the function _onMeasureStart in Wedget.js:

_onMeasureStart: function () {
this._displayChartLocation(-1);
},
