I have a component which iterates over a list of records and in turn calls a child component for each record returned. This works fine. I also have a lightning:slider in a seperate component which when changed, fires an application event containing a string to use as a filter on the list of records in the list component.

I can get the string value into the event handler and can see it logging in the console when changed. However, when I use this string value as a filter on the list of records I get an exception (sreenshot attached). My understanding is that lightning:recordViewForm is being passed a null record Id. However I dont see how this is possible as I'm checking the list size before setting the list attribute. Can anyone help?

  • I don't see the snippet for lighting:recordViewForm & handleRecordIdChange, where/how are you using that? – Jayant Das Oct 12 '18 at 1:30
  • Hi Jayant, apologies.. it's in there now - MovieSearchRecord. Thanks – Jay Oct 12 '18 at 8:42
  • With regards to your other point on handleRecordIdChange, this is not a function i have built anywhere in my org. I can only guess that it's something apex is doing under the hood – Jay Oct 12 '18 at 17:43

It ended up being a capitalised character on "Id" needing to be changed to id:

<lightning:recordViewForm aura:id="viewForm" recordId="{!v.movie.Id}" 

I've had the same error and this happened to fix it:

recordId="{!if(v.recordId, v.recordId, '')}"
