use case - everytime a page is requested the datetime variable is updated.
Solution:
declare the datetime variable as transient.
public class ExampleController {
DateTime t1;
transient DateTime t2;
public String getT1() {
if (t1 == null) t1 = System.now();
return '' + t1;
}
public String getT2() {
if (t2 == null) t2 = System.now();
return '' + t2;
}
}
<apex:page controller="ExampleController">
T1: {!t1} <br/>
T2: {!t2} <br/>
<apex:form>
<apex:commandLink value="refresh"/>
</apex:form>
</apex:page>
