Designer troubleshooting

Usually problems with the designer occur when JavaScript libraries are initialized incorrectly.

The following libraries are required by Designer:

  • JQuery
  • JQuery UI
  • JQuery.treeTable
  • Konva.js

In order to troubleshoot Designer, open browser console by pressing the F12 button.

Here's a list of typical errors:

1. Error: "Object does not support property or method 'dialog'"

You haven't initialized JQueryUI or you have included JqueryUI twice.

2. Error: "Unhandled exception at line 5, column ....... in ...../Scripts/workflowdesigner.min.js"

You are using an incompatible version of jQuery.

Please use the following scripts: jquery.js and jquery-ui.

3. Problems with mouse control in Chrome

In some cases AdBloсk blocks some mouse events.

To resolve the issue you need to disable AdBloсk and restart your browser.

4. Error: "Object doesn't support property or method 'addEventListener'" in InternetExplorer

Follow these instructions.

5. Error: "0x... - JavaScript runtime error: Unspecified error." from kinetic.js library

This happens when the library can't download images. Check that the path to images configured for the Designer object at imagefolder: '/images/' property exists and contains images for Designer.
