Could you describe me the errors ?

Indeed, I should (and would !) remove the last uses of this syntax !

EDIT : i have updated the release

[MihkelMänna]

I see you have already updated the release but here's my answer anyway.

I' not sure why these errors occured. I was testing the widget on the latest release of WAB on Firefox with latest updates. Importantly, the errors occured only after using other widgets in my app, so maybe the problem lies in my other widgets. Before the for-loop, the array is defined, but in the loop it gives the undefined error for the array element.

The for(var i in my_array) syntax is convenient but very "dangerous" in JavaScript, especially if the array has been "manipulated" (removes, slice...). I don't know why but sometimes this syntax does an extra loop (so the array bugs in this loop).

I try to avoid it but sometimes my php's and python's habits are too strong .

The bug may start with your others widgets but if the eDraw widget can avoid it, it's a eDraw's bug !

What version number is the release from 10/21 or 10/22?  Manifest.json says 1.3.3, as does manifest.json from a couple releases in the last two weeks of September.  I've been keeping copies of the older widgets, in the event something new has problems, with titles that reflect the release number.  Thanks.

Adam Gebhart,

The version is 1.3.3 :

- WAB 1.2 (1.3 on internal WAB numerotation)

- my third version under WAB 1.3 (internal numerotation)

It's a release from 10/22 because i live in your future (in New Caledonia).

I looked up New Caledonia. All I can say is, cool. Très bien!  Another place on ny bucket list...

Regarding snapping, is that limited to snapping to features drawn with the eDraw widget?  Or should one be able to snap to a line or polygon feature in one or more of our services?

Thanks again for doing all of this.  Your widget has received a lot of praise from our staff.

[JeremieCornet1]

Adam Gebhart​ Yes, Snapping is limited to eDraw's layer.

Although it's simple to configure snapping in code, the configuration's UI may be very complicated.

You can easily modify the snapping options in the code (and, why not, use a parameter in the config to do this) :

esri-webappbuilder-widget-eDraw/Widget.js at master · magis-nc/esri-webappbuilder-widget-eDraw · Git...

Thanks for the tip on snapping.  I haven't had time to look into it yet but hopefully will soon.

Hi Jeremie,  the bug where Point stops working after using Text is there still. I know you are probably aware but I just wanted to report I see it.

Regarding the interface refinement, I like it. I love the Copy!  I like the integrated import/export, too. Great work.  For our site I'm actually going to switch the up/down arrow icons. (to me it made more sense with them reversed but I know that's more of just a personal thing)
