QUESTION
I am currently trying to learn Kotlin with the help of the book "Kotlin Programming The Big Nerd Ranch Guide" and so far everything worked. But now I am struggling with the "lazy" initialization which throws a NullPointerException which says
Cannot invoke "kotlin.Lazy.getValue()" because "< local1>" is null
The corresponding lines are:
...ANSWER
Answered 2021-Jun-08 at 16:39When something like this happens, it's usually due to bad ordering of initialization.
The initialization of the Player
class goes this way:
- the
name
property has its backing field initialized with the_name
value - the
init
block is run, and tries to accessname
- the getter of
name
tries to read thehometown
property, but fails becausehometown
is still not initialized - ...if things had gone right, the
hometown
property would be initialized now with the lazy delegate
So basically you're trying to access hometown
before the lazy delegate is configured.
If you move hometown
's declaration above the init
block, you should be fine.
You can see the fix in action on the playground

QUESTION
I'm completely new to SalesForce and have inherited a report that's not working. Please excuse any incorrect terminology, since I'm learning about all this as I go. The report has three prompts: states, years, and members. All dropdowns are supposed to populate with data returned from functions in an APEX class. State, which populates from a picklist, and years, which is populated with a loop, work fine. Members, which populates from a SQL query, returns nothing. If I run the report without any prompts selected (which should return an unfiltered list of results from a SQL query), it also returns nothing. Both of the SQL queries return data when I execute them directly in the query editor in the developer console, but they return nothing when called from the APEX functions.
Here's the initialization code from the Lightning controller:

Right, it's a public page, it's called "Salesforce Sites". It's exposed to whole world without having to log in. These have special security in place because most of the time you don't want to expose data like that. At best you'd display contact us form, maybe some documents to download, product catalog... It's all very locked down, default is to ban everything and then admin decides what's allowed. It's bit unusual to have a Visualforce page + Aura component but ok, it happens.
You (and any other internal user) can see the results if you'd access this page from within salesforce. Something like https://mydomain.my.salesforce.com/apex/SearchBinReceiptsByYear and for you the page will work fine, "just" not outside of salesforce.
When exposed like that on the web - there's no logged in user. There's special "[Site Name] Guest User", you can see them if you search "Sites" in Setup. It has a special profile, also with [Site Name] in it. And nasty thing is - it doesn't show on the list of Users or Profiles.
Your code broke when Salesforce (auto)activated a critical update. Probably this one: https://releasenotes.docs.salesforce.com/en-us/spring20/release-notes/rn_networks_secure_perms_guests.htm There are some good resources on the net if you Google "Secure Object Permissions for Guest Users", for example https://katiekodes.com/salesforce-spring-20-guest-user/
Ask your system administrator colleague or read up a bit about sharing rules.
You'll have to go to Setup -> Sharing Rules. There's a checkbox that caused your stuff to break and you can't untick it.
Scroll down to your TRC Account object and hit "New". You'll need to create something like this, but with your criteria (TRC Member equals true)
Save, wait a bit (it might take a while to recalculate the sharing, you'll get an email) and try the page.
If it still doesn't work you'll have to check the Guest user's profile, it might need permissions to Read TRC Accounts and their Name field.
If it's Salesforce Sites - try this to find it: https://help.salesforce.com/articleView?id=000334554&type=1&mode=1
If it's a Customer Portal, Community, Digital Experience (they renamed the product few times) - try with https://help.salesforce.com/articleView?id=sf.rss_config_guest_user_profile.htm&type=5
Original answer
It looks like it's running OK because accounts (members?) are fetched first and in that fetch's callback (what to do when data comes back from server) you have helper.getLocationState
, helper.getYear
. And you wrote that these populate OK. It's not the best performance code but it should get the job done.
In no specific order...
Does the whole thing work OK for sysadmins? Or is it broken for everybody? If it works for sysadmins it might be something to do with sharing, your sysadmin should know (Setup -> Sharing settings is where you control who can see what. Maybe "mortals" are not allowed to see any data? Typically sysadmins bypass it. As a quick & dirty test you can modify the class definition to global without sharing class DataTableLocations
but it's a really ugly hack.
What happens if you open DeveloperConsole (upper right corner) while running this component, do you see any errors in the logs? What happens if in the console you go Debug -> Open ExecuteAnonymous and run this piece of code:

I am very new to salesforce. The boolean value in the parent component will be updated by clikcing a button. That is done. Now I want to toggle a class in a child component based on the parent boolean value. So my question is how can I always read the parent boolean value from the child?

Pass the parent attribute to child (in parent have something like

Actually there are few patterns for parent-child communication, pick what looks easiest/what's closest to what you already have

QUESTION
We had Selenium tests running on Sales Force non Lightning. Now I am converting to Lightning. There is a chain of menus to go through. I have successfully navigated to a certain menu, but now I have run into a problem. This is not the standard question about new element names. Here is the question. This is a small piece of what the page looks like (see below).
When using inspect with Chrome I can find the elements. This is what it looks like (a small cross section corresponding to above). The SPAN tag has the label ("Original Agreement") and the DIV below it will contain the box for the input value.

I want to open a binary file (yes, another soft synth soundbank) in ASCII format and check if it contains a string or not. There are multiple files in the folder, but I have written the appropriate code for it, I just want it to search the file for a substring.
I've tried opening the same format using the ASCII encoding function before, but it does not display the data I want (it displays some garbled data, totally different from what it does in a hex editor, in which the file is opened in ASCII). Can someone point me in the right direction?
