dataValues are not set if the user does not make any changes before sending in

[violaguttorm]

Description of the bug

The dataValues fields are not set in an Instance if the user never makes any changes, but just clicks through the form and sends it in. We prefill some data, which means that occasionally a form might be filled correctly from the start and the user could just send it in, but we rely on these dataValues to correctly route the data to us.

Steps To Reproduce

1. Use IInstantiationProcessor to prefill data that can be a correct form in a new Instance.
2. Send this in.
3. Observe that the dataValues fields have not been set.

Was not able to reproduce this. I have an app implementing an IInstantiationProcessor and created some dataFields in applicationmetadata.json (I think this is what was discussed in the Slack thread). As I instantiate the dataValues are filled in. They are also there after sending in the form.

Does it depend on how it is instantiated? I was doing this through the normal frontend

[violaguttorm]

Wait. Sorry, I actually forgot something important before reporting in. We actually prefill data in DataProcessing (IDataProcessor -> DataProcessRead) now (with a check to see if it has succeeded earlier to not double up). We do this since it's called anyway and we want the app to try again if the instance is opened again if the prefill failed earlier.

That might be the cause? If so, is there a way I can manually fill these values in? (Or maybe just make the call within IInstantiationProcessor too if that works when you test? 😅)

If relevant I can at least say that the data we filll into dataFields in applicationmetadata.json is data that the prefill fetched, so it didn't exist before instantiation ran.

Yeah IDataProcessor is never called if the instance is only instantiated I think, so if you only rely on IDataProcessor then that explains the issue

[martinothamar]

Is brg/rrh-innrapportering the right app? If the issue is reproducible there (while also prefilling from IInstantiationProcessor) then I can probably debug it

[violaguttorm]

I tried putting Instantiation in IInstantiationProcessor and that fixed it. Case can be closed. Thank you for your time.

I think the issue is that we don't update data values if you use a multipart request to initialise the instance and data elements.
