    Regression - IE11 error when fetching data and using DynamicForm

    SmartClient_v101p_2016-03-14_PowerEdition

    We use a custom paging model with our grid since we have to integrate with some legacy components in our application. Basically, we execute a new fetchData request on the grid with some additional parameters and the server returns the correct page of data. This worked in with SmartClient 9.1. I have simplified this code in the test case for brevity. Basically, when the user selects the page, I call fetchData.

    This functionality is now throwing an error in IE11 only. It works in Chrome with no exceptions.

    REPRO Steps:
    ========
    1. Load test case
    2. Select page 1 from the drop down
    3. Observe the console (attached image)

    As mentioned, this works in Chrome and in SmartClient_v91p_2014-04-10_PowerEdition. I tested a few previous 10.1 versions and they still had the issue.

    Looking at the debug JS, looks like something changed with focus on the dynamic form, but that's all I could ascertain.

    Did you intend to attach the data file SNQA-1219-1.json which the code tries to load?

      Yes, sorry about that. Here it is. You will need to rename it to .json.

        We've made a fix for this that will be applied to affected branches. It should be in the nightlies dated 2016-03-17 and later.
