Getter Block execution without VF reference

Question

My understanding of the Getter Setter is that getter is invoked if the particular variable is being referenced in VF Page.

However for the following code I see that Getter is getting called even if no variable reference is on the page.

    public class EmbeddedTest
    {
       public list<account> lAcc{
       get{
           system.debug('INSIDE GETTER');
           return null;
       }
       set;
       }

       public void checkChanges()
       {
          lAcc=[select id,name from account limit 10];
          system.debug('ACCOUNT LOG GENERATED '+lAcc);
       }
    }

VF Page:

<apex:page controller="EmbeddedTest">
  <apex:form >
     <apex:commandButton action="{!checkChanges}"  value="Click to change!"/>
  </apex:form>
</apex:page>

On clicking the button I see the below logs(in order):

08:37:22.0 (14537986)|SOQL_EXECUTE_BEGIN|[19]|Aggregations:0|SELECT id, name FROM account LIMIT 10

08:37:22.0 (19987384)|SOQL_EXECUTE_END|[19]|Rows:10

08:37:22.0 (20434238)|USER_DEBUG|[3]|DEBUG|INSIDE GETTER

08:37:22.0 (20537127)|USER_DEBUG|[20]|DEBUG|ACCOUNT LOG GENERATED null

Why does the Getter get called and make the list(lAcc) null even without any VF reference ?

Answer 1

You call the getter here:

system.debug('ACCOUNT LOG GENERATED '+lAcc);

Accessing the attribute value of lAcc in any way calls the getter.
