Unable to upgrade the Web AppBuilder for ArcGIS (Developer Edition) 2.8 app to the 2.9 version if the app contains the Edit widget.

対処法

Workaround (modifying the VersionManager.js of the Edit widget in 2.9/2.10 WebApp Builde)r:

NOTE : The Modified VersionManager.js is attached to the bug files

1. Be sure WebApp Builder is not running
2. Go in the folder client\stemapp\widgets\Edit in the 2.10 webapp builder folder
3. Make a backup of VersionManager.js
4. Modify the 2.9 section in VersionManager.js for this:

version: '2.9',

   upgrader: function(oldConfig){

    var newConfig = oldConfig;

    var i;

    var layerOrTableInfos = newConfig.editor.layerInfos.concat(newConfig.editor.tableInfos);

    for(i = 0; i < layerOrTableInfos.length; i++) {     

     var layerOrTableInfo = layerOrTableInfos[i];

     if (typeof layerOrTableInfo !== "undefined") {

      layerOrTableInfo.allowCreate = true;

      layerOrTableInfo.allowDelete = true;

     }

    }

    return newConfig;

   }

5. Launch WebApp Builder and do the import.

Explanation of the issue:

The problem is on the concat tableInfos and layerInfos when tableInfos is empty(undefined).

The variable layerOrTableInfos will have a undefined at the last position in the array(for the tableInfos) and the layerOrTableInfo.allowCreate will crash on that because the tableInfos is undefined.

I have added a check for any undefined
