2D-Measurement Error with 4.12

Question

Hello, I have an app that uses both distance and area measurement widgets. There is no problem with 4.10 and 4.11 APIs but with the new version, 4.12, I get errors when I click on the widgets. I am not sure if the problem is because of the materialize.css and If you guys have any ideas, I would be appreciated. The errors are below. Uncaught (in promise) TypeError: Cannot read property 'center' of null at Object.a._updatePolylines (DistanceMeasurement2DTool.js:15) at Object.<anonymous> (DistanceMeasurement2DTool.js:6) at f (dojo.js:386) at a.p [as callback] (dojo.js:387) at n (dojo.js:394) at dojo.js:399‍‍‍‍‍‍‍ AreaMeasurement2DTool.js:10 Uncaught (in promise) TypeError: Cannot read property 'coord' of undefined at AreaMeasurement2DTool.js:10 at Array.map (<anonymous>) at Function.c.updateViewModelAndCreateGraphics (AreaMeasurement2DTool.js:10) at Object.c._updateGraphics (AreaMeasurement2DTool.js:17) at Object.<anonymous> (AreaMeasurement2DTool.js:6) at f (dojo.js:386) at a.p [as callback] (dojo.js:387) at n (dojo.js:394) at dojo.js:399‍‍‍‍‍‍‍‍‍‍

Hi Ben,

Changing the units worked. I am able to switch the units after the measurements, so seems like the initial measurement in feet was the case.

Thanks.

Looks like if you base map has a spatial reference other than Mercator (stateplane in my case) the measurement widgets gives you a "Cannot read property 'coordsys' of null" error.  I think the changes in the Geodetic Computations section of the 4.12 release notes could be the reason.

Hi Esad,

The problem is coming from the units. if you switch 'feet' and 'square-us-feet' to 'metric' it should work.

Thanks for the find. This is an equivalency issue with 4.12. I have submitted a bug:
