Requirement: I need an LWC on Case record lightning page which should listen to another table called customobj1__c and display just the most recent record in that table. When the most recent record in customobj1__c table is updated by navigating to the detail page of that record I want the LWC which is on the Case record page to auto re-render and show the updated data.

Question: I tried using wire service to get this to work. I tried wire to property, wire to a function using a custom apex method but it didn't work for some reason. I read in documentation that wire service provides immutable data so I don't know if this is the way to go. I also tried getRecord of uiRecordApi and wired it to a property and a function both of them didn't work. How can we achieve this requirement?


You can hook up to to changes using the emp api and trigger refreshes to your LWC based on x criteria (this is generally in the form of an SOQL query)

So, you subscribe to a channel that listens for changes, and can handle your logic on the client.

  • That's a good thought. But looks like there are hourly limits on no.of events. We have almost 2000 users interacting with this table very frequently. So, I am guessing we will run into this limit pretty soon May 12 at 15:37
  • you can poll the server from the client every couple of minutes, but it's not the best approach.

  • Yeah I thought about that as well. We already have a couple other components doing that so I don't want to add another especially when something out of the box like LDataService can do this. Can you think of another approach? May 12 at 15:46
