"component IDs must be unique" when deploying Communities

 Communities are notoriously difficult to deploy. One error we ran across that was maddening was the following:

Several components in Support_Community/views/2023SearchEnglish.json , Support_Community/views/2023SearchClientCommunity.json share the same ID, but component IDs must be unique. Replace the following duplicates and try again. 77200210-1d47-414e-b202-8b72cc746faa

ExperienceBundle is a group of JSON files. It's meant to be deployed a one thing to wholly replace the one in your destination org, just like any Apex class or other metadata.

We found that in our case, Copado was inserting files from the destination branch that were no longer present in the ExperienceBundle.

 


Apparently, files in a subsequent export of the ExperienceBundle are likely to include duplicate IDs to those in prior versions, thus the conflict.

The solution was to go into git and delete the file from the destination branch, so Copado didn't have anything to merge into our current promotion. Philosophically, you can argue that no, one should not delete stuff from git, but we found that this was the only way to avoid having the tool add the "ghost" files from the previous version to the current deployment.

One way to detect the problem is by looking at your promotion branch in the git UI. Any files where the most recent commit is not the one you just made, is likely to cause this problem. That was the only way we found to detect the errors prior to deployment.

Another technique is to simply delete all the files from the destination branch in the views, variations, and routes folders. It's a blunt instrument, but you do have a copy of that version in its promotion branch should you need it.

Now, why Salesforce is reusing ID's, that's a real mystery.

Setting a DateTime to a Weekday in a Formula

Image
This is one of those things that took way too long to sort out. WEEKDAY() is a great formula function, but it only works on Dates.  Our requirement was to set the value to three days from now, but only if the day is a weekday, and put it in a datetime field. Thinking it through, they wanted the result to come out as follows. Cases received on Monday are due Thursday (+3 days) Cases received on Tuesday are due Thursday (+3 days) Cases received on Wednesday are due Monday (+5 days, skipping 2 weekend days) Cases received on Thursday are due Tuesday (+5 days, skipping 2 weekend days) Cases received on Friday are due Wednesday (+5 days, skipping 2 weekend days) Cases received on Saturday are due Wednesday (+4 days, skipping 1 weekend day) Cases received on Sunday are due Wednesday (+ 3 days) WEEKDAY() returns  an integer value, where 1 is Sunday and 7 is Saturday. Therefore: CASE(WEEKDAY(TODAY()), 4,now()+5, 5,now()+5, 6,now()+5, 7,now()+4, now()+3 ) Since WEEKDAY() only works o

"Disjunctions not supported" - Why Custom Metadata and Flow Don't Mix

Salesforce has been focusing a lot on Flow recently, as they should. It splits the difference nicely between Process Builder and Apex code. We recently used Flow to implement what I'd expect is a common use case - when a record is created, lookup a value from a table and update the record. In this case, it's a light lead score we call a "fireball" value. This worked great since in most use cases we'd get one record at a time. But we found during Lead conversion, we would get a few records through at a time, which caused the process to break with a really odd error: Error Occurred: This error occurred when the flow tried to look up records: Disjunctions not supported. After some research it became clear that this is the error you get when you try to query a custom metadata table using an "OR" condition. But my Flow didn't use an "OR" condition in the metadata lookup. The answer was lurking in this obscure documentation: When you define mult

Update Knowledge Articles in Bulk

Image
Recently we had a big Knowledge Centric Support (KCS) initiative where we generated a ton of Articles for use in a Community. (We're still on Classic Knowledge.) Problem is, some users forgot to tick the "Customer" box when creating the Articles. So those articles didn't appear to external users in the Community. You can update these Articles in bulk, but you need to use a few obscure hooks in Apex. This method will create a draft of the Article, update the Knowledge Article Version, and then re-publish without creating a new Version. The following code will update the 'IsVisibleInCsp' flag for a single Article specified in the 1st query, which will make it visible to Customers. Here's a bulkified version. This is heavy on the CPU so I run it 10 at a time. When going over these in bulk, you might run into a situation where there is an existing draft of an article that has been previously published; i.e., it's actively being updated. In t
