Issue overview: Currently coding a Lightning Component to update records on a custom object. However, every time I trigger the update (via a ui:button), the page freezes and I don't see any errors in the debugger or console. Cannot for the life of me figure out why it won't work.
Context: The ponent has a number of dropdowns that are populated with records (with the label being the record name). Selecting a new value in the dropdown and hitting "Update" calls the below apex to change a custom field (Status__c = 'Ready') on the new selected item, and then updates the records that occur before it (Status__c = 'Complete). I do all of my security and update checks in another function during init, so you won't see that here (I can post the full code if needed). Just trying to get the update to work.
I would be eternally grateful if someone could show me the error of my ways :]. Always been a huge fan of stackoverflow and looking forward to contributing now that I finally signed up. Thanks for your time everyone!
Apex:
@AuraEnabled
public static void updateMilestones(String deployId,Boolean prodChanged,String newProdMile) {
if( prodChanged == true && newProdMile != null ) {
try {
decimal newProdStepNum;
List <Milestone__c> newReadyProdMile = New List<Milestone__c>();
for(Milestone__c mil1:[SELECT id, Status__c, Step_Order__c FROM Milestone__c
WHERE Deployment__c = :deployID
AND id = :newProdMile LIMIT 1]){
mil1.Status__c = 'Ready';
newProdStepNum = mil1.Step_Order__c;
newReadyProdMile.add(mil1);
}
List <Milestone__c> prodMilesComplete = New List<Milestone__c>();
for(Milestone__c mil2:[SELECT id, Type__C, Status__c FROM Milestone__c
WHERE Deployment__c = :deployID
AND Step_Order__c < :newProdStepNum

mil2.Status__c = 'Complete';
prodMilesComplete.add(mil2);

Reset to default 4I believe the issue is that you have fallen into the all too mon trap of naming both a client side and a server side controller method the same (updateMilestones in this case). Try changing the name of either to make them unique and I expect that will get you running.
Yes, there is a bug on this and many of us have been making a very loud noise about getting it fixed!
Also we have a very active Salesforce specific Stack Exchange forum over here https://salesforce.stackexchange./ that will get more attention - especially if you tag your posts with lightning-ponents (e.g. I have my account configured to send me an email alert on every post tagged with lightning-ponents, locker-service, etc).
That might be javascript causing the error.As it's difficult to solve without knowing the error, I would suggest you debug the error.
Turn on debug mode. a. From Setup, click Develop > Lightning Components. b. Select the Enable Debug Mode checkbox. c. Click Save.
In Chrome Developer Tools, check the "Pause on Caught Exceptions" checkbox in the Sources tab. This can often help finding the source of an issue. Other browsers may have similar options.
Add a debugger statement if you want to step through some code. debugger; This is useful when you have a rough idea where the problem might be happening.
