Hi all,

maybe I am doing something entirely wrong here but it did work that way usually.

I am trying to embed a canvas app into my MDA. Basically the CanvasApp is there but does not load the data.
There should be the name displayed but the condition seems to be blank an no data passed towards the canvas app:

It seems like the old form designer does not work for me right now as I cannot find the custom control option for one of my fields.

The ModelDrivenFormIntegration is setup and at least shows the necessary data inside the canvas app designer:

I am a bit blank what else the issue could be. I remember that the only way of making that app work was directly adding it inside the form but this also does not work as the canvas app control directly wants the binding column, an app name and an app id. If not provided the app itself crashes.

I am binding it to the 'Account Name' Column as this is always present in the form.

Any idea what else there is to try or which workaround I could use?

Hi Lucas,

Most likely root cause i could find was:

The app may have been added using the newer Canvas App control experience instead of the classic embedded Canvas App integration flow

In that setup, ModelDrivenFormIntegration often does not receive the form context correctly

Recommended fix:

Remove the current embedded Canvas App control

Remove the existing app/control from the form

Save and publish the form

Recreate the embedded app using the classic integration flow

Open the Main Form

Add a field to the form

Go to:
Change Properties -> Controls

Add:
Canvas App control

Choose:
“Create a new app”

Bind the control to a guaranteed populated field
Recommended:

Account ID (preferred)

or Account Name

Test with a simple formula first
Example label formula:

ModelDrivenFormIntegration.Item.'Account Name'

or

First(ModelDrivenFormIntegration.Data).name

Important testing requirement

Test only on already saved records

Embedded Canvas Apps often fail on unsaved/new records

Publish everything in this order

Save app

Publish app

Save form

Publish form

Publish all customizations

Additional note:

If the app references ModelDrivenFormIntegration inside App.OnStart, this can also fail because the integration context is not always available during startup

Better approach:

Use Screen.OnVisible

or directly reference ModelDrivenFormIntegration.Item

Hi @Lucas001

This is correct - just to clarify, did you specify the app name and app id, as this could be a possible explanation? I assume you did as the canvas app appears in your model driven app screenshot?

Hi @CU18050859-2,

Already asked the AI and found the same steps. Problem is that the control for the form where one can add the canvas app as control is not available, neither in the account table nor in any other. The account table behaves different than expected as all fields are somehow not named:

@timl

that's what I can do and as the app is loaded it seems good to me. I am just not sure why the context is not properly passed at all. The Canvas App has been created outside and than added via the CanvasApp Control Component. I did not hide the label to show the Column name does match the binding column.
Any idea?
