My requirement is to allow user to select multiple records and update a flag (Is_Cancenlled__c) in backend. This includes pagination as well.
I am facing below issues, while performing this in LWC.
a. Row selection across the pages is not perisistent. While I navigate to next or previous page, the selection from earlier pages are lost. b. While i debugged the issue, I found out that the rowselection method is getting fired even in pagination. Any one can explain the behaviour please?
Sample LWC code for this purpose would be a great help
I have Batch apex Class and Schedulable class. I am looking for the syntax to call the Batch apex class from the trigger or calling the schedulale class from Trigger, which inturn calls the Batch apex.
The problem I am facing is, I have batch apex code updating two fields in Opportunity line Item(OLI). While I run the code for complete batch the values in the field are updating correctly. However, If I spilt the batch apex in two or many, I am facing the issue of the last batch value getting updated in Opportunity line item instead of complete one.
for ex:- Consider 3 record of value 50 each, I am expecting the field in OLI to be updated by 150 and it is updating rightly while I run the batch for Database.executeBatch(job,3); where as if I split the same as Database.executeBatch(job,2); then the field is getting updated by 50 instead of 150.
I read, Database.Stateful can be used to maintain the state accross the batch, can someone help me with sample code for Database.stateful illustrating how to use the function.

I have some batch apex. I start a batch and going by the debug logs, it looks like everything is running smoothly - no errors occur in the logs, and their statuses are 'Success'.
However, monitoring the Apex Jobs page, the job shows up once started, however, a few batches in, the status detail updates to "First error: Attempt to de-reference a null object". And that's all - there's no log an no clue as to where this problem is actually occuring. Looking through the debug logs, there's nothing there that shows an exception
I'm not perfect, it's perfectly possible I have a line of code doing something silly at a certain point - but any ideas how I can find out where I'm going wrong?
