I need an urgent help..!
Create the lightning component which show the selected Accounts from the list view and on click of send button sends the email to selected Account's email id. (here a Email is a custom field on account)
use email template
for email content.

Please post the code..

Thankyou..!

there is a custom object 'Amount' with number value field 'Amnt' which is related to account by lookup. There is a field on account- 'Amt' it should show the sum of amount if the sum of amount is greater then 100 then it should not allow to insert any child record for a perticular account and should give an error- 'you have reached a maximum limit'

Hi All,

I'm a bit confused on this. if we have a standard user profile with (CRED) on all objects and OWD set for private (let's say on Opportunity object)

Will the standard user be able to CRED on any opportunity record (owned or not-owned)? or will they have zero access to opportunity records they do not own?

I was under the impression that the user will have zero access to CRED any records they do not own. Unless permitted by role hierachy or sharing rules.

Thanks alot everyone

I have a site for self-registration which calls Site.createPortalUser()  to create a new portal user if it is a new user. It works perfectly on site registration page. The problem now is that I have to capture facebook login and create portal user for facebook users. Current code has callout function to get facebook user's email, userid and username, etc. And then, pass those info to the same function used for site registration page. All parameters are correct, just don't know why Site.createPortalUser()  always give me null userId? Anyone has any idea about this?
