No Basemap Choices in WebAppViewer

AdamRepsher

When I configure the Basemap Gallery Widget in the Web AppBuilder for ArcGIS‌, the basemaps are not available in the Web App Viewers. I have tried this in current versions of IE10, Chrome and Safari (iOS).

I have a basemap gallery group that I have configured in our Organization, if that matters.

Is anyone else having problems making the basemaps appear for the web app viewer?

I just tried this and it worked for me:

1. In a separate tab enter one of the following URLs

---www.arcgis.com/sharing/rest/content/items/<itemid>/data?f=pjson

---<orgkey>.maps.arcgis.com/sharing/rest/content/items/<itemid>/data?f=pjson

Change the <itemid> and/or <orgkey> for the Web Map id

2. Open the details of your web mapping application and click edit.

3. At the bottom change the purpose to Configurable.

4. Copy the json text from step 1 and paste it in the Configuration Parameters section at the bottom.

5. Edit out the empty json tag that is in the basemap gallery section that looks like {},

6. Save and refresh and that should do it.

It looks like the latest release of AGOL (March 2015) fixes this issue for me. Still waiting for the next version of Dev to fix it.

Thank you for the suggestion Stan.

My problem remains because I want to have this app available in ArcGIS Online‌. Since you gave me a workaround, I am assuming that I cannot manipulate the app code in AGOL directly. Correct?

So, I am also assuming that this is a bug in the AGOL version of Web AppBuilder for ArcGIS‌.

Yes that is the one.

NathanEnge

You're talking about...?

{

"basemapGallery": {

"basemaps": [

{},

.........

StanMcShinsky

remove the empty json tag. delete the whole line: {},

Also having the same issue. All my basemaps including the one used in the webmap are Web Mercator.

Even if I remove all the Esri content, and just re-add the layer used for my basemap in the webmap, I still get a blank Basemap Gallery.

I am using the downloaded dev edition.

This is the JSON in the config_Basemap Gallery.json.

{

"basemapGallery": {

"basemaps": [

{},

{

"title": "Basemap",

"thumbnailUrl": "/webappbuilder/apps/4/widgets/BasemapGallery/images/default.jpg",

"layers": [

{

"url": "http://cvrdgis2.ingram.cvrd.local:6080/arcgis/rest/services/Planning/CVRD_Base_Mercator/MapServer"

}

"spatialReference": {

"wkid": 102100

}

]

}

If you are not using the developers version of WAB then here is another route.

Download app—Web AppBuilder for ArcGIS | ArcGIS

Follow the instructions to deploy the app.

Download the app link here http://www.arcgis.com/home/item.html?id=fffd70b754594c54bc58d90d4e897e19

on step 2 add that url (www.arcgis.com/sharing/rest/content/items/<itemid>/data?f=pjson or <orgkey>.maps.arcgis.com/sharing/rest/content/items/<itemid>/data?f=pjson) to your browser and input your app id from AGOL (the long number at the end of your map url). here is where you can access that config file and get rid of the empty JSON tags (towards the end of the file).

Can you tell me how to access the config file of the WebApp in AGOL?

Thanks!

Our basemap is different from ESRI Public basemaps, which is local projected SR, but still accessible to WebAppViewer (above)...

AdamRepsher

All of the base maps are of the same spatial reference as the Esri base maps.

larryzhang

Adam,

If the custom web map (a basemap for your organization) available, it looks that you can pick it up from the following path (below)...

LemaoWu

Do all basemaps in your basemap gallery group have different spatial reference from the current map you are using? The widget only displays the basemaps sharing the same spatial reference as the web map loaded in the Web AppBuilder.
