I tried multiple times so far in my developer edition to import data from with in the Dream Home app in lighting. It spins for ever. without that I am not able to get any badge or continue that lesson further. Please advise.

In one of the you tube video on sales force I saw that a transaction can be full or partial meaning fully rollback and partially completing the transaction.
In the case of full rollback it is database DML direct.
In the case of partial rollback it is via a page method.
 
Even without Salesforce this is true.
Under this situation instead of calling a stored procedure directly via execution at the backend only it either commits or roll backs.
If the same stored procedure is called from within a page then it is via page method. Here it is partial commit.
We experienced this recently.
However in order to solve this partial commit to full commit (either commit or rollback) at the page level can we implement holdlock on the calling stored procedure.
Will that work?
What other methods I can implement to prevent partial transaction?
 
Please advise.

I'm trying to create a visualforce email template that I can attach in a workflow that goes out to certain users/account teams whenever a case comment is created/modified.


I can load the Apex Class but not the email template or component. I get the following error for component:


Error with email bc  Ican't create component! Do I need to create a custom field for comments named last case comment?
