Driving me crazy. Please help! I have a perfectly working sollution, correctly factored according to the challenge. I've compared against other solutions on the message boards and I don't see where the miss is. It matches all the criteria the challenge asks for but I get the very obtuse error message:
"The campingList component doesn't have a Quantity field using an inputNumber UI component" - which is clearly an incorrect statement as the UI components are supposed to be on the campaignListForm component.

Here is my code (not posting the apex controller, camping.cmp, campingHeader.cmp or campingListItem as they haven't changed in this challenge and are all working ok):
(Note: I do have a namespace on my org, perhaps that is the issue? Custom field names are xxx__MyField__c, but this hasn't been a problem before)

I am still getting this error:

Challenge Not yet complete... here's what's wrong:
The campingList JavaScript helper isn't saving the new record to the database or adding it to the 'items' value provider.

My App save the new record into the database and add it to the "items" list.
Thanks for your answers!




 

I'm trying to complete the Connect Components with Events trailhead and am getting this message when checking the challenge:

Challenge Not yet complete... here's what's wrong: 
The campingList component doesn't have a Name field using an inputText UI component.

This does not make sense to me as this challenge moved the input form to a new bundle. Why does it seem to want a inputText UI component in the campingList component?

I am using an inputText UI control in the form component and including the component on the CampingList component.

I feel I'm missing a step.  Ideas?

Thanks.

I'm designing some flows for which I'd like the finishLocation behavior to change depending on the path of the flow.  Depending what happens in the flow, I need users to end up at different pages when the flow is over.  Is there a way to do that without writing custom code?
