JS Destructuring and Inconsistent casing.

I found that context (PowerApps) and Xrm (unified) objects have issues when it comes to destructuring.

const { openForm } = Xrm.Navigation; (This works with legacy ui)

const { openForm } = context.navigation;

Both of these will result in error when openForm is executed. I am guessing that the openForm is not permanently bound to its context object.

Also, casing of "navigation" is inconsistent between the 2 objects. They should be the same.

Hi @rexkenley ,

Firstly, the question that you asked is more about Dynamics.I suggest you post your issue in Dynamics forum. It will help you solve your problem faster.

This table shows the most commonly used function in the Dynamics CRM Xrm.Utility class, and the method calls in Dynamics 365 v9.

Dynamics CRM Client API	Dynamics 365 v9 Client API
Xrm.Utility.openEntityForm	Xrm.Navigation.openForm
Xrm.Utility.openQuickCreate	Xrm.Navigation.openForm
Xrm.Utility.openWebResource	Xrm.Navigation.openWebResource
Xrm.Utility.alertDialog	Xrm.Navigation.openAlertDialog
Xrm.Utility.confirmDialog	Xrm.Navigation.openConfirmDialog

So please make sure that where do you use this function.

If you are using Dynamics CRM Client API, please try this function: Xrm.Utility.openEntityForm.

Here's a doc about it for your reference:

This is not only happening in dynamics, this is ALSO happening in PowerApps Component Framework. And if I am not mistaken, isn't Dynamics CE also PowerApps as announced by Charles Lamanna?

"With the announcement that the Dynamics v9 UI is a PowerApp and development will be shifting to a PowerApp design experience, this brings enormous implications to not only the Dynamics 365 CE platform but everything else. No, you heard me correctly. Dynamics 365 is a PowerApp. Charles Lamanna (Business Application Platform Director at Microsoft) gave the keynote talk at Denver Dynamics Day last week."

Destructuring is a JS feature introduced with ES6. Destructuring works with v9 legacy and is only BROKEN with v9 Unified (which is PowerApps) and PowerApps Component Framework.

"The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables."
