infragistics.lob.js:289 Uncaught TypeError: Cannot read property 'fields' of undefined

Just above line 289 reads:

* Infragistics.Web.ClientUI Hierarchical Grid 15.2.20152.1027

* infragistics.ui.grid.framework.js
*/

Would missing these cause the JS error?

I’m currently using the following:

Hello Adam,

Thank you for posting in our community.

The names of the JavaScript files containing the combined scripts for all of IgniteUI are as follows:

– infragistics.core.js :  shared dependencies(required)

– infragistics.lob.js :  a line-of-business controls

– Infragistics.dv.js : all data visualization controls

<!-- Ignite UI Required Combined JavaScript Files -->
    <script src="http://cdn-na.infragistics.com/igniteui/2015.2/latest/js/infragistics.core.js"></script>
    <script src="http://cdn-na.infragistics.com/igniteui/2015.2/latest/js/infragistics.lob.js"></script>

 

Along with these files also the css for the IgniteUI controls should be loaded. Css files are as follows:

    <link href="http://cdn-na.infragistics.com/igniteui/2015.2/latest/css/themes/infragistics/infragistics.theme.css" rel="stylesheet" />
    <link href="http://cdn-na.infragistics.com/igniteui/2015.2/latest/css/structure/infragistics.css" rel="stylesheet" />

 

Also the jQuery and jQuery ui scripts should be loaded. The final list of the scripts should look as following:

You can also refer to our online samples browser where you can find working samples with script references for different controls.
For further reference of Ignite UI scripts I believe you will find the following articles from our documentation useful:
