QUESTION
I am trying to display parent( Survey ) & child ( Survey participants ) details retrieved from the database ( Salesforce ).
I am using LWC ( Lightning web component ) to display the details.
There is a limitation in lwc that you can't access data from a related object using '__r' ( This means related object ) directly in HTML component.
Here is my data:
...ANSWER
Answered 2021-May-29 at 10:21Try this. I hope you are intending to flat the participant object
QUESTION
Is it possible to change code (html, js, css) in Lightning Web Components online in Salesforce? Something like this I don't know to run it according this manual.
Because I would like to check code imported from VSCode. It seems to me that the code/component is not updated.
...ANSWER
Answered 2021-Mar-11 at 11:28Currently, you can't "import code online".
To check if your code been deployed correctly you can use chrome devtools and see if your files been deployed and used. There is a cache machanizam also which you can disable -will reduce performance https://www.salesforcecodecrack.com/2019/09/disable-browser-cache-during-lightning.html

I have develop LWC component which is normally used by normal users. In that lightning web component button is there as below.
...ANSWER
Answered 2021-Apr-23 at 17:58I think this is not a good idea to get current user profile from lwc. Because User and Profile are two different object in Salesforce. You can only get user profile id by import it.

QUESTION
When I have two methods shoppingCartPlaceOrder() and shoppingCartSetOrderLineItem(). I need wait when shoppingCartPlaceOrder() ends and get Id of order from this method. Then it's needed to execute shoppingCartSetOrderLineItem() and use that Id. There is an catch in handlePlaceOrder(): 'this.shoppingCartPlaceOrder(): error'.
Here is simplified code:
...ANSWER
Answered 2021-Apr-09 at 08:06The only thing you need to do basically is just chain your this.shoppingCartSetOrderLineItem() with the previous promise result as you can see in the snippet I have pasted.

It's needed to wait until the function getFile() ends. I call this async function in other function. In "async function getFile()" is bug: "Unexpected token. A constructor, method, accessor, or property was expected."

QUESTION
In LWC Super badge Challenge 2, we have to create a lightning message channel named BoatMessageChannel.
I tried creating it with the name boatMessageChannel coz the naming should be in the camel case.
But while verifying the channel I'm not able to complete the challenge though I have verified that the channel is properly deployed by including it into lwc.
After searching a while I found that I have to use BoatMessageChannel.messageChannel-meta.xml rather than boatMessageChannel.messageChannel-meta.xml. but while deploying this file I'm getting the following error:
...ANSWER
Answered 2021-Mar-21 at 07:02The Lightning Message Channel should be in the camel case is the best practice.
But in challenge 2, they are applying the test case which checks the LMC with Pascal case, and hence it fails to complete.
Note: while deploying from the file editor context we are getting the mentioned error that
SourceElementDoesNotExist: The LightningMessageChannel named boatMessageChannel was not found in the workspace.
To deploy it, we have to right-click on the file from the file explorer which will not give the error mentioned above.
QUESTION
I have posted a similar question on Salesforce stack where the context is Lightning Web Components(which is just an extension of HTML Web Components). I am asking here because I would like to reach a wider audience.
In their documentation they say that it is not recommended to get/set properties of a custom component in the connectedCallback() hook. Does anyone here know why would this recommendation be given, as I use this hook specifically for getting/setting properties.
...ANSWER
Answered 2021-Mar-08 at 06:45There is no problem with reading or setting properties with connectedCallback callback handler. The original guidelines has to do with the fact that props can change after connectedCallback and this function is executed only when component is attached to the DOM tree. It means that your code will not be able to properly handle the reactivity.
It is not a technical constraint per se; it more like good architectural guidelines when dealing with web components.
General rule of thumb:
- Use
connectedCallbackfor one time stuff like templates, setting up observations (ensure that observations are cleaned up indisconnectedCallback. - Use
gettersandsettersfor managing the property watchers. Also, do not handle async workflows within setters. ExamplePromise.then(), etc. The reason for this is to properly handle the cancellation for already running requests when prop changes. Thus use observables preferably set inconnectedCallback.
